SuperATV’s 8” GDP Portal Gear Lift is the biggest, most powerful lift on the market. With eight inches of lift and your choice of a 45 or 60% gear reduction, it truly is the ultimate portal lift for power and performance.
Here’s a complete breakdown of everything that goes into our 8” portals, what makes them tick, and why they’re just so damn good.
The core of what makes all our GDP Portals best-in-class is our gears, and 8” portals are no exception. We use 9310 VAR steel alloy. That might not mean much to you, but it’s an incredibly strong alloy that’s used by the likes of Boeing and Bombardier for aircraft engine gears. You’ll be hard-pressed to find a better gear material anywhere in the side-by-side industry.
That’s the kind of strength we put into our portals. But strength alone doesn’t cut it. They need precision and finesse to run smoothly. Our gears are precision ground so they mate perfectly. Perfect mating is important because even the strongest gears are made weak without proper meshing. And the better they fit together, the quieter, cooler, and smoother they run.
Our portals are designed for hard rides and a heavy throttle. They won’t tear themselves apart just because you ride like you stole it.
World-class gears enable us to put awesome gear reductions in each 8” portal box. You have the option of either a 45% or 60% gear reduction.
Gear reductions convert more of your engines power into torque, and torque is key to turning bigger tires. That makes 8” portals with a gear reduction built in a match made in heaven. You get the clearance to run huge tires and you have the boost in torque to be able to turn them. It doesn’t get any better than that.
Picture yourself rolling around with massive 40” tires that are so heavy you could barely get them mounted in the first place. They eat all your machine’s power just turning them, giving you sluggish acceleration and and piss-poor performance. But with a 45% or 60% gear reduction, they perk right up to feeling like stock again and then some. Even with huge tires, you can jump off the line like your UTV is built for the drag strip.
Speaking of tires that are heavy enough to crush a Prius, portals prevent them from tearing up your drivetrain despite that weight.
But how do they do it?
It comes down to the position of the gear reduction. Since the gear reduction is in the hub, your axles, differential, prop shaft, and transmission all benefit from the gear reduction too. It’s easier to turn big tires with a gear reduction so your drivetrain parts will work less than they would on a stock machine!
Another sneaky feature you can find on most our 8” portals is a forward and rear offset.
The backing plates on these portals are rotated a couple degrees from vertical, which gives you a 1.5″ forward and rear offset. That makes your wheelbase 3″ longer overall and gives your machine tons of room for bigger tires and more stability when climbing hills or crawling over nasty obstacles.
We know how well a portal seals isn’t super flashy or exciting, but GDP Portals are sealed really damn well. You’d be surprised how easy it is to screw something like this up, so we made sure we didn’t. That’s part of the reason why our 8” portals don’t include vents. They compromise the seal and offer little to no benefit for you.
From the gears to the housing, we cut no corners.
The drive gear is the gear that you insert your axle into—the one at the top of the box. We seal this gear against the housing itself instead of your axle.
If you had a dirty, beat-up, or scratched-up axle, the gear could have a hard time sealing against your axle surface. This could, in some instances, allow oil to leak out (or dirt to get in) around your axle.
That’s why this gear seals against the housing—it doesn’t matter how crappy your axle is. It will stay sealed even if you decide to use a tree branch for an axle.
We use an O-ring gasket to seal the two halves of the 8″ portal box. This gasket seals around the perimeter of the housing and around each bolt hole. It sits in a nice little machined groove that ensures it stays in place, even when you’re really abusing your portals. It’s simple and super effective.
We’ve already talked about how our portals let you choose your gear reduction, but that’s not the only customizable options you get. With your choice of housing materials and universal wheel hubs, you can make your portals work for you.
You get to choose cast or billet aluminum for your housing materials. What’s the difference? Billet gives you that awesome machined finish that looks great and provides a boost in overall strength.
If you’re not into that, you can save a few bucks and go with a cast housing. Don’t worry—it’s engineered for extreme strength too. You don’t have to drive differently just because you went with a more affordable material.
Our hubs have lug patterns that fit with almost any side-by-side wheel. With GDP Portals installed, you have more wheel options than ever before.
If you want to get a little bit wild with your wheels, you can get our Universal Truck/Jeep hubs. They give you lug patterns for most trucks, Jeeps and a ton of other wheels too.
Between our universal and truck/jeep hubs, you’ll have access to tens of thousands of wheels so you can make your 8” portals the perfect set for you.
