If you're not doing these things, then you can expect your ride to be plagued with accidents and injuries—the hallmarks of a decidedly un-fun day.
You need a big gear and a little gearLet's start with the very basics of a gear reduction. You first need a big gear (let's say it has 30 teeth) and a little gear (let's say it has 15 teeth) and put them together. Turning one gear will cause the other gear to turn. Super simple. If you decide to turn the large gear by hand, you'll notice a lot of resistance, but the connected small gear make 2 rotations for every one rotation of the large gear. You will gain a bunch of speed (output rpm is 2 times the input rpm) but lose torque. If you decide to turn the small gear by hand, you'll have almost no resistance, but you'll have to turn it three times to make the big gear turn just once. You lose speed but gain torque. Now speed doesn't do you much good if you don't have enough torque. You can spin that gear as fast as you want but as soon as you put a wheel and tire on there, it'll stop dead. That's why you mostly see gear reductions that increase your torque and decrease speed. That trade-off is much more favorable because the extra torque will make up for a lot of the lost speed when you're riding off road. Your speed is compromised by uneven terrain but torque helps you keep going.
It's all about leverageBut how does using a little gear to turn a big gear get you more torque? That simply has to do with leverage. Everybody's favorite old dead guy, Archimedes, said "Give me a long enough lever and I shall move the world," or something like that (ancient translations are wonky.) The point is, the two gears moving together act like two levers trying to move each other. The big gear has a big lever and the small gear has a small lever. As you know, it's easier to turn a stubborn nut with a long handled wrench—and the longer the better. It's the same thing with gears. Your little gear is turned by a motor in the center and has a lot of leverage against the large gear that is being turned at the edge of the gear. And out pops your bonus torque. Now you've got a healthier drive train and the ability to run bigger tires. If you're still not sure, imagine you have a frozen nut with a breaker bar on it: that's the big gear and the radius that gear is the length of the breaker bar. You are the small gear and your radius is the length of your arm. You can turn a much tougher nut in this setup than you could without a breaker bar, but it'll take a lot longer to unscrew it completely.
Gear reductions everywhereWe get the gear reduction in our portals by applying this science (portals have a third gear between the big and little gear. The middle gear's job is to make sure your wheels turn in the right direction and it doesn't affect torque. Just FYI.) And obviously the same thing happens in your standard gear reduction kit that you stick in your transmission. Gear reductions exist all over your stock machine as well. They're in your differentials and transmission. But those are just stock. So check out SuperATV.com to see how you can take some simple physics lessons and turn them into over-the-top off-roading fun.
Winter is happening right now! In fact, we're about halfway through it, so we're in the very heart of winter. Now, there are exactly two kinds of people in the world: those who drown in malaise and cold once the holidays are over and those who gear up and get riding! With a little help from SuperATV, even the sourest winter grump can glean a little joy from the cooler months.So grab some gear and charge into the great outdoors! This winter wonderland is only around for a little while.
Snow PlowThis one's obvious, right? If you live where it snows enough to make it dangerous getting out of your neighborhood, or you live far enough in the country that it takes 2 days for your road to get plowed, then you need a snow plow. And we've seen plenty of snow this season to justify the purchase You don't want to wait to get a snow plow either—don't be reactive. You want to get one before there's snow on the ground if you can. We see this year after year: Snow Plow sales are slow month after month. A few start shipping out to the North where it snows a little earlier in the year. Then, BAM! A snow storm sweeps across a large swath of the US and suddenly we sell virtually all of our snow plows overnight. No matter how much we stock, we just get cleaned out. So grab a plow while you've got the chance! We've got complete kits that come with everything you need. They're designed with a frame that you can leave on year-round and a quick connect for the plow blade. All you need is a winch to operate.
WinchesSpeaking of winches, you need one for more than just plowing. They're useful all year long and I don't think you should ever go riding without one. But they're especially useful in the wintertime when you can pull your neighbors out of ditches on your snow day. We've got 3500 lb, 4500 lb, and 5000lb winches available.
Windshields, roofs, and doorsNow that you've got your roads cleared, what's stopping you from taking the ol' Ranger out for a spin? Oh, right, it's freezing. And speeding through the country with that icy cold wind in your face is a good way to lose some fingers and a bit of your nose. Lucky for you we've got full cab doors, windshields, and roofs for your Ranger, RZR, and Defender so you can keep riding in comfort and keep the cold out. These things are great because they seal you in completely. You'll be surprised by just how warm your cab gets with some doors and windshields. We've got a full range of windshields, roofs, and doors for dozens of other vehicles if you don't happen to have a Ranger, RZR, or Defender. Feel free to head on over to SuperATV.com to see these and other items to soup up your ride, and keep riding all winter long.
I installed the Gear Driven Performance portals on my custom rock crawling and racing RZR. I raced the second trip out with them and won the Ultra4 Hot Springs event on a brutal 9+ mile course. The amount of gear reduction is excellent for 32-35" tires. I'm now able to use high range like a stock machine. I'm an axle killer and I have yet to break an axle since installing the portals. The extra clearance and load off the drivetrain is phenomenal. -Ross Pilgreen, Little Rock, Arkansas
GDP Portal Gear Lift from SuperATV has Turned my 2015 RZR 900 Trail into a tire shredding, mud-slinging beast. The portal lift keeps my axles from extreme angles and reduces stress on drivetrain with the 30% gear reduction. The super dense Midwest mud doesn't stand a chance. -Scott Malone aka Northern Rider, Lake Island, Illinois
I will never own another RZR without portals. We didn’t brake one factory axle, or burn up one factory belt. For us that is very very rare. The 30% gear reduction relieved so much stress throughout the whole drivetrain. Oh and by the way we are running 34″ tires! The added ground clearance made typical obstacles easier and allowed us to stretch outside our comfort zone and try harder and more difficult obstacles. A big concern was what were we going to lose off the top end and that concern was quickly put to rest when I still hit 65 mph with ease. I am running a 2015 RZR XP 1000 and it pulls harder off the line than a new stock turbo. That is no exaggeration. These portals are designed and built so well. -Jake Andersen of SlikRok Productions, Logan, Utah
