Maybe you’ve seen portal gear lifts when you’re out at the ride park. They’re installed on anything from Polaris Rangers, Can-Am Defenders, and RZRs to Sportsmans and Outlanders. You know they make whatever ATV or UTV they’re on look cool and people seem to like them.
Now you’re intrigued, but you don’t know where to start. You’re not even sure what exactly a portal gear lift is. What are portals on UTVs? What are portals on ATVs? And what is the best portal gear lift? We’re here to help.
We’re going to start with the basics here. What are portals on a side-by-side? A portal gear lift is a type of lift kit that has a gear reduction built in. Instead of lifting your suspension like a traditional lift kit, portals put the lift and gear reduction right in the hub.
Now, how does a portal gear lift work? Once you understand that, you’ll have a better idea of what they can do for you. There are two things every portal gear lift does:
They achieve this lift/gear reduction combo with the portal box. Instead of a traditional lift that pushes your suspension down, the portal box replaces your stock wheel hub. As a result, the lift is right in the wheel.
Portals use gears to get power through the lift and to the wheels. The secret sauce of portals is that these gears provide a gear reduction. And gear reductions provide torque. Torque is very useful on big lifts when upgrading to bigger tires. That’s because bigger tires actually reduce your vehicle’s ability to output torque, resulting in worse acceleration and a wimpy-feeling gas pedal. A gear reduction gives you back your power.
If you want to know more about the gear reduction in portals and how it boosts torque, check out A Deep Dive into How Gear Reductions Work.
Together, the lift and gear reduction can improve performance, increase ground clearance, and give you more tire clearance.eduction give you the perfect recipe for high performance, major ground clearance, and bigger tires.

The big question is, why should you get a portal gear lift? What does it actually do for your ATV or UTV, and how does it make your ride experience better?
First of all, if you want to lift your machine, a portal gear lift is probably a better option than you think. That’s because it raises your machine, and gives you a gear reduction that can help take advantage of bigger tires (if bigger tires are what you want).
Plus, it’s perfect for a ton of different ride styles. It’s a natural fit for mud boggers who need tons of clearance and power to push massive tires through mud holes, but it’s good for a whole lot of other riders too. Tackle rock gardens with all that extra torque or cruise trails with extra oomph that makes you smile every time you hit the gas. GDP Portals can work well for many different kinds of riders because we have options that fit a bunch of different needs.
Let’s break down the pros and cons of adding portals to your machine.
Pros of upgrading to portals:
Cons of upgrading to portals:

A portal is made up of two main parts:
Let’s assume you know what a lift is and move on to the gear reduction, how it works, and why it’s important.
A gear reduction is when a small gear turns a bigger gear (and not the other way around). The small gear doesn’t have to do much work to turn the big gear, but the big gear turns slower. This means that a wheel attached to the big gear will turn slower, but it’ll be a lot harder to stop than if it were attached to the small gear directly.
You can try it out for yourself on a bicycle. Set your bike to the lowest possible gear, and you’ll see that you’re pedaling the smallest sprocket while it turns the largest sprocket on the rear wheel (with the power being transferred via a chain). In this setup, you’ll have to pedal more, but it’ll be easy. The same goes for a gear reduction.
But why do you want that extra power? Because you lifted your machine and added big tires!
Big tires are the opposite of a gear reduction—they’re hard to turn and eat up all your torque. The gear reduction in portals gives you your power back (and then some), so you get better acceleration and tons of torque to roll over obstacles, no matter how big your tires get.
With a big lift and a big boost of torque, portals are ready to take on any obstacle.

Now that you know how portals work, you need to figure out what the best portal gear lift for you is. First, remember that the lift height and gear reduction work together. But the two biggest factors to consider are the tire size you want and the type of riding you do.
For almost everyone out there, the reason you get portals for an ATV or UTV is to get bigger tires. That’s why we consider your desired tire size to be the most important factor to consider when you’re choosing which portal gear lift you need.
So first off, what tire size do you need?
You need to think about where you ride. Are you a speed freak who loves tracks and open trails? You’re probably the kind of rider who would benefit from a small upgrade in tire size. If you run 29” tires now, you might need a 32” tire. If you’re dealing with rocks and mud, you probably want to go as big as you can stand.
You also might just want big tires because they look badass. That’s totally valid too. Portals can help you out with that.
And bigger tires need bigger gear reductions. Check out our Portal Gear Reduction Calculator to figure out exactly what you need.
There are a lot of different portals to choose from.
You have different lift heights:
Different gear reductions to go with those lift heights:
And different housing materials and gear setups:
If you’re not sure what a dual idler configuration does for you, we can explain. Every hub has a drive gear (where the axle goes in), an idler gear, and a driven gear (that connects to your wheel hub). That means all the power transfers through the idler gear, and the best way to make that part of the chain stronger is to add a second idler gear to share the load. That’s what our dual-idler configurations do—they share the load going through the portal hub to help prevent idler failure.
Some combination of these will be perfect for your riding style and desired tire size.

Now that you’ve got your tire size and ride style in mind, all you need to do is pick your GDP Portal Gear Lift. We’ll break it down for you.
Do you like to go fast?—If you like the speeds available on your stock machine and just want a few more inches of tire diameter, you’ll want a 4” portal gear lift with a 15% gear reduction. The smaller gear reduction will help maintain your OEM speed profile while still giving you some extra low-end grunt.
Check out these portals for riders who put the pedal down:
Are you a trail rider?—If you’re the kind of person who just likes to cruise down trails for the love of the outdoors, GDP Portals can help you out there too. Our 4” portals with a 15% or 30% gear reduction will give you plenty of ground clearance to get over obstacles, and give you the torque-boosting gear reduction that helps you roll through washouts and over logs.
Do you like rock crawling?—Rock crawlers need the perfect balance of tire size and power. We recommend a 6” portal with a 30% or 45% gear reduction, depending on your chosen tire size. If you’re hard on your machine, upgrade to our dual-idler configuration for maximum strength
Do you love mudding?—The best mud monsters are built with big tires and big torque in mind. So go as big as you can with 8” GDP Portals and the biggest gear reduction you can handle. Keep in mind that when you go this big, you’ll need a frame stiffener, and you’ll want to consider adding track bars too.

Portals can be a bit intimidating when you get five or more boxes in the mail for one kit. Don’t let that discourage you—installation is pretty straightforward, but it will take some time to complete.
GDP Portals come complete with every nut, bolt, and brake line you need to get it installed. They even include a socket for the recessed castle nut. There’s no welding, cutting, or custom fabrication. Everything just bolts up.
That being said, here are a few tips to make sure installation goes as smooth as possible:
With the hard part out of the way, you just need to keep your portals up and running. But it’s not a big deal.
Here’s a quick rundown on how to keep your GDP Portals running smooth with regular maintenance:
Follow those steps, and you’ll be rolling on your GDP Portals for years to come.

I have your 4 inch gen 3 portals at 30% reduction tires are your 32x14x10 intimadators original tires where 27x14x10..how far off will my speedometer be off now say at 60mph reading.
Hey Richard, unfortunately, there are a lot of factors that can play into this. There are a lot of apps nowadays that can tell you your speed. We would recommend downloading this and compare that to your speedometer. Thanks for the support!
Can they be used for the street for everyday use and can a locking hub be installed
Hey Richard, thanks for tuning in! Yes, with proper maintenance, they can be used on the road as well. A locking hub cannot be installed; however, a locking differential can.
I have your 4″ portals and a set of your warrior 35″ tires. Portals are 30% and also IGR of 25% the latter compensates for the increased tire diameter and the portals give the torque to go through mud and a bit of rock crawling. I am using Honda Talon 1000X OEM wheels with 1.5″ spacers in the front and 2″ spacers in the rear to allow enough clearance between the portal plate and the wheel. If move to the 6″ or * GDP portals will it increase the width? Thanks and the current combination is killer just looking for a bit more height and considering a little bump in torque going to 45% on the taller portals. This would also leave room for even larger tires in the future.
Hi George! First off, it sounds like you’re making some pretty great aftermarket choices. :) As far as your question goes, going to 6″ portals will not increase the width. Our 6″ portals have the same width as our 4″ portals installed. You would keep the same width, gain 2″ of height, and would need 18″ wheels or larger to clear the portals. Thanks for the support!
Question; I have a 2020 Polaris S 1000 and I’m considering putting on 4 ” portals . If I also install 1.5 ” wheel spacers will that give me enough room without changing my stock 12″ wheels ?
Hey Ron, unfortunately it will not work. 14″ minimum wheel size is required for the 4″ portals. Thanks for reading!
I have a 2019 Polaris Ranger 1000 XP Crew High Lifter Edition, we installed your 6” big lift last year. We are running 38” Outlaw 3’s on 22” rims. We are continually breaking stuff, so obviously we need to add portals. I am just trying to figure out which portals we need? The Ranger HL edition comes with 15% gear reduction so i’m not sure if i need 30% more or if i need to go with 45%? Can you help??
Hey Dana, with your setup and tires, I’d suggest 45% gear reduction. We do have a dedicated portal technical support team in office if you’d like to reach out for more advice: 855-743-3427. Thanks for the support!
I have can am defender max hd8 can I run 6″ portals with 40 inch tires and be ok or do I need to stay with 37’s
Hey Jason, thanks for reaching out! The 37’s will not rub if you install the 6″ lift with the 6″ portals. However, if you only add forward offset A-arms instead of the lift, you could only run up to a 34. Unfortunately, there isn’t a combination that we currently offer where we could recommend running a 40″ tire without rubbing. We appreciate the support!
2025 Rzr Pro R Ultimate. Putting 6” portals on to gain more clearance and to maintain factory geometry in the suspension. That is more important than bigger tires. But I still would like to know max tire sizes. My question is two part. What is the biggest tire you can put on the factory machine with the 6” portals and not rub anything? And secondly what size tire would you recommend to run with a 30% gear reduction on the portals and factory setup?
Hey Robert,
You’re able to run up to a 42″ tire with our 6″ portals installed. Running those 42″ would work with the 330% gear reduction.
Hi, I have a 2018 Polaris XPT 4 with 4” portals / 30% reduction. Trans clutch and motor are stock. What I am noticing is that I am not putting any load on my turbo at all. The problem with that is I’m building heat in the engine and turbo. The machine will tackle any obstacle in Moab without going over 4000 rpms. The machine will reach higher rpms and when I do hit the gas harder my engine temps drop.
What can I do to mitigate this?
Clutch kit – Add weight to the primary, lighter primary spring?
Hey Shawn, thanks for tuning in! I’d recommend a Rev1 ECU Tuner that will kick the fan on at a lower temperature. Check out our tuners here: https://www.superatv.com/polaris-rzr-xp-turbo-hand-held-ecu-tuner Feel free to give our customer service team a call if you have more questions, 855-743-3427!
I have a 2017 can am mav turbo ds, 72″ with 33″ tires on 15″ rims, will 15% reduction work on these rims and set up, will I need a lift and will I remain at 72″? Thanks, Mike.
Hey Mike, if you’re talking about adding portals with 15% gear reduction, it will depend on the wheel offset and will add about 9″ to the width. Feel free to give us a call at 855-743-3427 for any portal tech support!
I have Krx trail edition w/ outer bead lock 15″ stock wheels, will i need spacers for 4″ portals
Nope, you won’t need the spacers. Thanks for the support!
good morning tyler
how do you like the 4 inch porter on your krx
i was thinking about doing the same i have 35 inch tire and thinking 4 inch portal wich do u think
Hello i currently have a 2014 rzr800s with 4″ gen 1 15% reduction portals and runing 35″ motohavoks would like to go with 6″ portals for the extra 2″ and also bigger and stronger than gen1 but idk what size reduction i should get 30% or 45% im also runing a muddrr clutch kit from epi idk if that makes a difference but reving about 4,000 rpm going 5 to 15mph my average speed
Hey Tony! It’s a personal preference, really. If you want a little more speed out of the gate, go with more reduction. If you’d rather have a little higher top end speed, less reduction. But it will also pull better with less reduction, and the clutch kit SHOULD help offset some of that top end loss. Check out our portal calculator to get estimated speeds: https://www.superatv.com/portal-calculator Thanks for the support!
I just purchased some 6” portals for my 2010 rzr 800 and wondering if wheels off of a can am will fit the portals
Hey Victor! You can make it the correct bolt pattern for sure. However, the wheel size will more than likely not work because the 6″ portals require an 18″ wheel or larger with no more than 5″ back spacing. Feel free to reach out to us at 855-743-3427 for anymore technical help!
I have a 2000 2020 want razor XP pro ultimate was wondering if I put 4″ portals on would it be OK to run them in 30 fives in the dunes and what is guessing top speed with the foreign portals with 35XT Warrior tires
Hey Mitchel, yes – you should be able to run 35s. Check out our portal calculator to get estimated speeds: https://www.superatv.com/portal-calculator Thanks for tuning in!
I have a Honda Pioneer with 3” lift and 1.5 A-arms. I’m currently running a 30” BKT. I’m going to purchase the 6” portals and run a 35” tire.
I’m looking for a good all around ride. Mud, trail and top speed. What gear reduction do you recommend? The 30 or 45?
Hey Zach! Sounds like a great setup! I would probably recommend 30%; however, we have a portal calculator to help with this because it does really depend on your personal preference. Check it out: https://www.superatv.com/portal-calculator Thank you for the continued support!
I have a 2012 canam commander 1000 with a super ATV 6 inch lift and I want to add 6inch portals and already have 18 s for my rim size I think the tires are 33 can I use the 6 inch portals with this set up
Thanks for tuning in! Unfortunately, the GDP portal gear lifts are not directly compatible with the SATV Commander 6″ suspension lift kits. We have seen customers fabricate kits to make the combination work, but it’s not something that we offer or recommend due to the added stress to the Commander frames.
I have 2016 terxy4 800 im running 35’s on 20’s with a 6″ lift but not sure if a 4″ portal will be enough !! Should id go 4″ or 6″ portals ?
Hello! Thanks for tuning in. Both the 4″ and 6″ portals would give you enough clearance for those tires. If you’re wanting to know if it’s enough as far as gear reduction goes, that comes down more to personal preference and ride type. If you’re sticking with the 35’s, I would go with the 30%. If you’re wanting to go to a bigger tire or if your main riding is crawling, then you could consider the 6″ with a 45% reduction. If you need any more help, give us a call at 855-743-3427 and our portal support team will get you figured out!
I would do a 6 inch or 8 inch if you plan on goin bigger on tire size the 6 in has 45 percent gear reduction an the 8 inch has 60 percent
I have a 2020 can am x3 xmr turbo. I ordered 6” portals with the 30% reduction. I plan on running 40x24x8.5 BKTs. Will i have any issue as far as reduction wise? Should i go to a lower reduction?
Thanks for reaching out! To answer your question, it will depend on what you’re wanting out of the machine and where you ride the most. Typically, with that size of tire, you’d want more reduction. Check out this link to get an idea of where you would be speed wise. https://www.superatv.com/portal-calculator Thank you for the support!
if i buy 4″ portals 15% reduction can i buy gears to change to 30%
Hey Ronney, thanks for checking in! Unfortunately, this is not an option since they are different boxes. Feel free to give our portal support team a call at 855-743-3427 for any questions!
What is the estimated time on putting 4″ portal kit on a teryx4?? Thanks..
Depending on the mechanic ability, it could take anywhere from 3-5 hours. Thanks for tuning in!
I have a 2018 Maverick X3 XMR Turbo R (72″ model). The engine, clutch and suspension are stock. I have flashed the ECU to lower the fan temp with the Dynojet PV3. Since then I have added GDP portals at 30% reduction and 35″ Motohavoks. I’m not sure what the stock gear ratio is on the XMR’s but I’ve now added 30% more reduction so I’m sure it’s due to the higher RPMS it is now running but now it is running a bit hotter than I would like. When in the mud (mostly clay) it’s not unusual to see 210-215°F. I was wondering if I should make adjustments or upgrade the stock clutch or maybe add a second radiator to help with this. With the added dear reduction I operate in Hi most of the time as well since Lo is extremely Lo
Hey George, we appreciate you reaching out! Your question is a hard one. There could be any combination of issues. You could have air in the system, dirt or mud in the radiator, or you could even just have a plugged-up air filter. Unfortunately, we do not currently offer clutches or radiators for this machine, so it’s hard for us to pinpoint the exact issue.
I have a Polaris sportsman 850 with 31” out laws and im thinking of install portals on it i do a combination of trail riding and mud riding and was wondering which gear reduction i should go with the 15% or the 30% i rarely get the bike above speeds of 30 mph since I enjoy just cruising
Hi Dylan! You really can’t go wrong either way. Something that might help you make the decision is our portal calculator. It’ll give you an idea of where you’ll be speed wise. Check it out: https://www.superatv.com/portal-calculator Thanks for the support!
I have a Polaris General with a 24% gear reduction in the transmission. I currently have 32″s and looking at 4 inch portals. Since the transmission is done, what gear reduction do you recommend, 15% or 30%? Would never go larger than a 35 inch tires. Also, how far does the portals push the tires out per side. Thank you
Hey Rick! For gear reduction recommendations, it really depends on what kind of riding you’re going to be doing the most. Check out our portal calculator to help you make the decision: https://www.superatv.com/portal-calculator. Lastly, the portals will push out 4″ per side. We appreciate the support, and thanks for checking in with us!
I have a 2018 Polaris Ranger Crew 900 with an 8″ lift, 15″ rim, and 35″ tires and im looking to go with the 6″ portal gears. Can I run spacers in order to keep the 15″ wheels I have on now? Also, what would my ideal tire size be for a total of 14″ lift?
Thanks for checking in! Unfortunately, we wouldn’t recommend the number of spacers you would need for clearance. With our 6″ suspension lift and 6″ portal gear lift, you would be able to clear a 38″ tire with no contact.
I have a 2018 ranger xp 1000 looking to install 2 inch forward A arms 6^ portals on 33 what gear ratio would I use
Then if you wanted to use 35s will the gear ratio be the same
Hey Andy! What gear ratio you use is all going to depend on what kind of riding you do the most. Or are you more interested in figuring out what tire size would get you back close to stock? Check out our portal calculator as it may be helpful in figuring out what you’re after: https://www.superatv.com/portal-calculator
I have a 2016 Rzr 1000 Turbo, I have two sets of wheels/tires. The stocks and an aftermarket mud set ( 35 inch tire and 20 inch wheel) I love the way it runs and the speed it produces. I like to trail ride and the occasional mud hole along the way. I don”t plan on mud Bogging but I do like to hit a hole here and there so my question is. With a 6inch portal and my mud set… 35 inch tire with a 20 inch wheel, am i going to loose my top end speed?
Hey Darius! If you choose to go with the 30% gear reduction on our 6″ GDP portal gear lift, you should balance out your top end speed by running 35″ tires at a decent amount, while increasing your acceleration speed. You can also help improve top end with a clutch kit and/or ECU tuning. Here is a link to our portal calculator that should give you a better idea of where you would be at speed wise with each gear reduction option as well as tire size. https://www.superatv.com/portal-calculator Thanks for the support!
I have a 2021 Polaris general XP four deluxe will a 4 inch portal keep my 33” tires from rubbing the bike
Hey Jimmy! We have to be careful about recommendations like this because each machine will be a little different due to shock/spring wear. So if there is any type of contact at full shock compression or turn, we have to say it doesn’t fit. I will say that we’ve got some offset arms that are in the works that should help with this, but we’re still a couple months out ETA wise. Feel free to check back in with us!
Have 4 inch portals with 32 inch juggernauts on my maverick xmr. Speedo says 82 mph but GPS said 51mph. What’s the gear ratio?
Hey Alex, thanks for checking in! It’s hard to say for sure without more information, but based off what you’ve said, it sounds like you’ve got a 30% portal. Feel free to call in at 855-743-3427 to confirm.
Tyler first I’d like to start by saying what an incredibly well written article. Your advice to other riders above has completely convinced me that these portals are the only way to go. Ok, so here’s my situation: Tomorrow I’m buying a 2019 RZR XP 4 1000 HighLifter. Currently sits on 29.5” tires on a 14” rim. Based on height restrictions in my garage, I think the max height I’ll be able to go with, will be the 4” portal with a new set of 18 or 20” rims on 35” mud tires. My question, is how much gear reduction should I go with? Also, do you think the dual idlers are substantiated for a novice trail rider like myself? Or is the added strength more suited for hardcore muddies and rock crawlers? Appreciate your help!
Hey there, Steve! With 35″ tires, we recommend a 30% gear reduction. You’ll need the extra torque to turn those big ol’ tires! And when it comes to the dual idler option, we absolutely recommend it! Dual idlers are a no-brainer in almost any situation, and well worth the investment. It sounds like you’re going to have a pretty sweet setup! Thank you for reading!
I have a 2021 Polaris general Xp 4 1000, and i’m going with 15”X10”X32” tires with a 4” portal lift
And 15% reduction. Is this a good set up for high speed trail riding and slight rock climbing
Here in the desert terrain?
Hey Steve! Between 32″ and 35″ tires at 15% reduction is a good setup. You can also take a look at this link to give you an idea on top speed: https://www.superatv.com/portal-calculator Thanks for tuning in with us!
im ordering 18″ STI HD Beadlock wheels for 17 x3 on 6″ portals. will a 6+1 rim work
Hey Nick! The wheel requirements for this are: 1) 18″ or larger wheel, 2) 18″ wheels cannot exceed 4-1/2 backspacing, and 3) 20″ and larger wheels cannot exceed 5″ backspacing. Thanks for checking in with us!
I have a 2010 polaris rzr 800s I am installing your 5″ suspension conversion kit high clearance whats the biggest size tire that would fit and what size rim would i need for your 6″ gear reduction lift for trail and rock crawling oh and what % reduction do you recommend.
Hey Eric. Based on what you’ve told us about what you’ve got installed, with the conversion kit and portals, you will max out at 34s with no rub. You could possibly go a little bigger but it will most likely rub in a turn with the shock compressed. If you’re running a 34 or bigger and rock crawling, your best bet would probably be 45% gear reduction. Check out our portal calculator to help you figure out what’s best for you: https://www.superatv.com/portal-calculator Thanks for the support!
Hey I have a 2021 Polaris general, with yalls 3 inch bracket lift.. I’m soon gonna get some 6” or 8” portals, what would my max size tire be for 6s or 8s with the small lift?
Hey Gage! Assuming you’ve got the non-XP version, with the 3″ lift, you’ll be able to run up to 30s without rubbing on 6″ portals. With 8″ portals, you’re looking at up to 35″ tires. If you want to go bigger than that, you can always look at adding some A-arms on top of the lift. We offer recommendations at the bottom of every portal page description, helping you figure out what suspension/tire size you can get. If you press “Read More” on the description tab, you’ll see this at the bottom: https://www.superatv.com/polaris-general-8-inch-portal-gear-lift We also have a portal calculator that helps you figure out what you need: https://www.superatv.com/portal-calculator Thanks for the support, and feel free to give us a call with any other portal questions at 855-743-3427.
i have a 2021 2 seater rzr highlifter edition i believe it states on the website it has a 55 percent lower gearing im looking to add 40 in tires on 24 rim and want to go with the 8in portal. all thats offered is 70 percent gears. will that be to much reduction for this set up
I have a kawasaki MX mule 2022, are yall making portals for this machine or are there some in the works for this machine
It looks like we don’t have Pro-MX portals on our list yet. That doesn’t mean we won’t make them, but it does mean that it’ll be a long while before they’re available if we do. Thanks for checking in!
I have a 2022 RZR 1000XP4 at the moment it is completely stock
I am wanting to go 37x20s. Which Portal setup would be best for Trail and Mud Riding? Also any other Mods I may need to fit these rims and tires? What Offset for Rims?
Hey Jason, if I were you, I would go with 6″ portals and a 30% gear reduction (or 45% if you want a little more oomph. 30% will get you close to stock feel even with bigger tires). To fit 37″ tires you’ll need to add 1.5″ A-arms. They’ll still probably rub when you hit big bumps, but they’ll get the job done. For that setup, you just need to make sure you have 5″ or less of backspacing.
You could also get 30% 4″ portals with 1.5 offset A-arms and a 3-5″ lift kit to fit 37s. The wheel backspacing for this setup is the same.
Either way, it should be an awesome setup.
I have a 2022 mule pro FX I am looking at these portals for a slight lift for ground clearance. I do not extreme mud this as it it is a tool around the place but we also like to go to the river. I am looking at 15% reduction would this be ideal for a SXS that is mostly used too pull a trailer, a sprayer, bee hive equipment, and yet go on a mild trail?
I’m currently running a 64 inch Can Am X3 XMR with 32 inch XTR370s on System 3 14 inch beadlocks.. There is currently no issue with power, even though the tires are heavy, still stock clutching and only 120 hp. I want to run 35s with 4 inch portals (stock suspension otherwise), but I would like to retain similar feel currently and am worried 30% would be too much and am really leaning to the 15%. It does appear that 35s on 15% would be slightly lower geared than I am now, but with 35s. Seems like it would be about perfect. I may end up with more power later as well, so that is a consideration. I ride almost exclusively mountainous terrain of the PacNW, tight, steep, rocky, rutted and muddy and the machine is a straight animal as is. I can’t imagine the places it will go on 35s and portals…but I wanna find out. Thanks for any input!
Cheers
Sounds like you have a solid plan. There is a lot of personal preference when it comes to choosing your gear reduction, but I talked to a few guys here about your setup and riding terrain and they said they would go with the 30% reduction. Upgrading to 35s and adding a 15% gear reduction at the same time will make it feel more like you’re running your stock 30″ tires, so if that’s what you’re after, your plan is spot on.
However, you will notice a big improvement with 35s and a 30% gear reduction. And unless you spend a lot of time near your machine’s top speed in dunes or something, there’s really no downside to jumping up to 30%. It just gives you more low-end torque. If you get a tune or upgrade your clutch down the line, you’ll be happy you went with 30% for sure.
Like I said, it’s a personal preference. We know lots of folks on both sides of the coin that have loved them. I will say that 30% with 35s is probably the more popular choice though. Either way, I’m sure you’re going to love it.
I have a 2022 Commander max xt with 3” spacers and 35” XTR’S and 15” Beadlock. 4+3 system 3’s want to go 4” portals how much wider will my machine be?
Hey Tony. All our GDP Portals are 4″ wide, so you can count on them making your Commander 8″ wider overall.
Thanks Kevin I am leaning toward dealing with the width to get the gear reduction! I am a GM at a Harley store and we have a Powersports store as well so likely my price will be best buying from my employer thank you for the answer!!
Folks who go with portals rarely regret it! If your trailer can handle the width, the pros definitely outweigh the cons. And enjoy your employee discount 👍
hey guys my name is gage McNeece an I have a 2014 Honda foreman 500 trx500fm1 to be exact but I really need gear reduction because I mud ride an I run 30 inch silverbacks as of now an I need to know if I should go with portals Or go with the actual gear reduction in my engine I don’t plan on going to a bigger tire size but when I get in thick mud my four wheeler doesn’t do well an I’m thinking about doing 40 percent primary so anyone feel free to comment back to me with some answers
Hey Gage, your only option at the moment is a transmission gear reduction. We’re working on a 4″ portal gear kit, but that’ll only go up to 30% and won’t be out for a while. Plus, I’m not sure it’ll fit a 2014 when it does come out. I don’t see anybody else selling Foreman portals either. So that should simplify things for you at least! If there were a portal gear kit for your quad, I would recommend going that route 100% for the extra ground clearance, tire clearance, and drivetrain protection, just to answer your question.
We also don’t sell transmission gear reductions for the Foreman, but I’m sure there are plenty of options out there for you. Thanks for the question!
I currently have your 6’lift kit on my ’17maverick x3 200hp to the rear wheels i want to go with you duel idle either 6’or 8′ I’m running fuel maverick 22’son 37.5 I’m nit a mud guy what so ever just wanna redeem that hp.which portal gear reduction would you think would be sufficient planning on around 300 hp when she is completely done
Hi—if I’m understanding your question correctly, I think a 30% gear reduction will get you very close to your previous speed.
You can find the 6″ portals here: https://www.superatv.com/can-am-maverick-x3-6-inch-portal-gear-lift-g3
And the 8″ portals here: https://www.superatv.com/can-am-maverick-x3-8-inch-portal-gear-lift

Hey Rick!
It depends on what other suspension you have on your machine. Give us a call and a technician can help you out! 812.574.7777
As far as I know its stock suspension, please advice
Will ranger 900xp/1000xp portals fit a ranger 800?
Hey Tyler,
It depends on the year of the XP 1000! Give us a call for more information. 812.574.7777
Got 4 inch portals 30% gear reduction pulled them off a 2016 Polaris ranger 900 look to see it they will fit on a 2015-16 Polaris Ranger 800 6×6
Hi Robert,
Unfortunately, the portals from your Ranger 900 won’t fit the Ranger 800.
Hi i have a 2016 outlander xt 1000r and put a 6″ super atv lift and getting 6″ portals and 40″ tires and was wondering what gear reduction to get and what speeds to expect with 30% and 45% ? Any help would be apreciated ,thanks
Hi Steve,
We would recommend a 45% gear reduction when running large tires. Give us a call if you have any further questions! 812.574.7777

i want 6” portals for a 25’ rzr pro r 4 ultimate that will mostly be in mud. i haven’t decided between 40’s or 42’s, could you recommend what gear reduction in the portals would work best overall for either size? i understand 6” may be short for the tire size but i will likely install forward arms to ensure clearance in the front, trying to keep it from being too tall for what i want even with big mud tires.
Hey Cody,
We would recommend going with a 45% gear reduction!
Do I have any portal options for a 2023 Polaris Ranger SP 570 Crew Midsize? Any chance the old XP570 can be made to work?
Hey Trevor,
Unfortunately, we don’t have anything for your rig. We never recommend using from other machines!
I have a 2019 maverick 1000r sport and just acquired a set of 35 mothavocs on 20 inch wheels,I trail ride mostly but where I ride i can get in some pretty nasty mud holes,will the 4 inch portals with 30% be what I need with the 1.5 a ar,s?
Yes, a 4” portal with a 30% gear reduction is a solid choice for running 35s, especially in mud.
I have a 2022 Pro XP4 Ultimate that I’m looking to go with 4″ portals on 35″ roxzillas, which measure 34.5s. I will be using the stock 14″ wheels initially, but will upgrade at a later date. What spacers should I buy and do I need forward arms?
Hey Raymond,
We recommend adding 1.5″ A-arms to fit that size tire with our 4″ portals. Wheels need to have a center hole of at least 3.25″ (82.55mm) or require a 1” wheel spacer.
I have a 24 Polaris General xp 1000. I have 31” tires now and want to go to 33 or 35’s in the future. Can I buy 4” portals with 30% reduction and run the 31” tires until I get the bigger tires mentioned?
Hey Kim,
Do you have a lift kit or anything on your machine? We don’t recommend going larger than a 29″ tire with our portals.
