Description
Make Your RZR a Mud Monster
If you want to take on the
nastiest, sloppiest mud, you need SuperATV’s Polaris RZR Pro R 8″ Portal Gear
Lift. It gives you the clearance you need to take on even the thickest muck
with confidence. You can customize your GDP with a 45%, 60%, or 70% gear
reduction and a billet or cast aluminum housing to transform your RZR into the
mud monster of your dreams.
What’s a Dual Idler?
We spent years testing and refining our dual idler gear portals to reach
perfection. The two idler gears are CNC-ground for a flawless fit that gives
you more reliable torque transfer and better overall performance. They’re made
with durable 9210 steel alloy for longevity too. With GDP’s quality and
experience, you know you’re getting a hardcore portal that can carry your RZR
over every obstacle in its path.
Pick What You Want with
45%, 60%, and 70% Gear Reductions
We all know that big tires =
badass riding. But they’re not just for looks—big tires help you make giant
mud pits look like mud puddles. These 8” GDP Portals give you the room and the
gear reduction you need to get HUGE tires on your Pro R. But big tires take a
lot of power to get them rolling. You have your choice of a 45%, 60%, or 70%
gear reduction to help with that. Gear reductions help redistribute power once
you’ve added those massive tires, so your machine’s performance doesn’t have
to suffer.
Protect Your Drive Train
With
portals, the gear reduction happens right in the hub. That means you’re
putting less stress on your drivetrain trying to move those big ol’ tires.
Your axles, differential, prop shafts, and transmission will thank you for
adding GDP Portals.

unleash your machine’s potential.
Housings and Backing
Plates Built Tough
We make GDP Portals to put up with the worst
abuse UTV owners can dream up. Whether you go with cast or 6061 billet
aluminum housings, you’ll get incredible strength thanks to our trail-tested
design. Pair that with 5/16” backing plates made with advanced steel alloy and
you’ve got the roughest, toughest portals on the market. Does your RZR deserve
anything less?
- 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
Advanced
Gaskets, Seals, and Bearings
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
