SuperATV Polaris Ranger XP 570 6" Portal Gear Lift

GDP didn’t make the first side-by-side portal kit on the market—just the first kit that anybody gave a damn about. With Gen 3 GDP Portals, you get to choose between 30%, 45% and 60% gear reductions, and you can add dual idlers. So you get to decide just how wild you want to make your Polaris Ranger XP 570. GDP is blazing the trail with quality and versatility. No matter how you ride, GDP Portals will redefine your Ranger.

Perfection takes time. After years of research and development, we’ve made our dual idler gear portals unlike any other. By placing a second idler gear in the portal box, the load gets spread over twice as much surface area for more reliable torque transfer and the strongest gear set you can get. Two idler gears don’t do a thing if they’re not mated perfectly, though. Precision CNC grinding ensures ours do. Our gears are made from the industry’s toughest 9310 steel alloy. Didn’t think dual idlers mattered? With GDP’s quality and experience, they finally do.

GDP Portal Gear Lifts are designed to enhance every rider's experience. They’re not just for mudders or rock crawlers—they’re perfect for trails, dunes, deserts, and more. Get a smaller 30% reduction for faster rides that still pack plenty of torque. Bigger tires for rocks or rough rides require a bigger gear reduction—like 45%. Build the mother of all mudders with a 60% gear reduction. Then take your strength over the top with dual idler gears. Portals give you your torque back so your monster build can still rip harder than the rest.

A Gear Reduction That Protects Your Drivetrain

Thanks to the fact that the gear reduction goes right in the hub, portals reduce the stress on your axles, differential, prop shaft, and transmission. That makes this a lift that’s easier on your drivetrain than riding stock, and your most vital parts will last longer, too. It’s a win-win.

We know how you ride. You won’t slow down just to protect your machine and you shouldn’t. That’s why GDP is designed to be the strongest on the planet. Our cast and billet aluminum housings are tougher than any other. Combine that with 5/16” backing plates made from an advanced steel alloy, and our portals are unstoppable.

Our housings are reinforced for gear retention and optimized for oil flow

Advanced steel alloy backing plates are stronger than chromoly

Enhance with Portal Blood—gear oil formulated for GDP Portals

There are no gimmicks and no vents because vents do more harm than good—we know because we tested them

Our portals use:

Advanced gaskets and O-rings with excellent oil resistance and low deterioration rates

A sealed input gear and double-lipped output seal

100% sealing coverage throughout so you can forget about oil leaks

Double-angular contact output bearings to prevent premature wear

Roller idler and drive bearings to maintain perfect gear meshing

Get the confidence to send it by adding a SuperATV Frame Stiffener. A big GDP lift, big tires, and big torque are all, well, big. So brace your chassis and keep the pedal floored without worry.
