Polaris RZR XP 6" Portal Gear Lift

Top of the Industry—GDP Portals

Transform your Polaris RZR XP into a trailblazing beast with the SuperATV GDP 6” Portal Gear Lift. It'll lift your ride and give you all the power you need to conquer the trails. These portals are customizable to suit every rider's preferences. Pick a 30%, 45%, or 60% gear reduction, choose your housing material, and if you get wild, go all out with dual idler gears for unbeatable strength. It's your ride—do it your way!

What Is a Dual Idler?

Perfection takes time. After years of research and development, SuperATV has made its 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 these do. The 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.

Get a Gear Reduction to Match Your Style

Adventure can take you anywhere, and GDP is all about wild rides. Whether you're climbing mountains or exploring muddy trails, GDP Portal Gear Lifts will make you do it better. For faster rides with plenty of power, choose the 30% reduction. If you're into rock crawling or rough terrain, go for the 45% reduction. And if you're building the ultimate mud machine with massive tires, the 60% gear reduction is the way to go. Don't forget to boost your strength with dual idler gears to make your monster ride stand out.

GDP’s Gear Reduction Reduces Drivetrain Wear

Portal gear lifts put the gear reduction directly in the hub, which gives you a huge advantage. This means your axles, differential, prop shaft, and transmission all benefit from it, so they’ll wear less and last longer than stock.

Smartly Designed, Trail-Proven Strength

SuperATV doesn't compromise. The portal gear lifts are built to be the toughest out there, from strong gears to your choice of billet or cast aluminum housings and advanced steel backing plates. When it comes to ultimate strength, SuperATV's RZR XP portals have got you covered.

The 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—SuperATV knows because it tested them

Advanced Gaskets, Seals, and Bearings

The 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
