Unstoppable GDP Portals for the Pro S

Don’t get stuck in the mud! Upgrade your Polaris RZR Pro S with SuperATV’s 6" Portal Gear Lift. You’ll get more torque to push through deep mud and a lift to conquer tough terrain—all with massive tires. Choose from a 30%, 45%, or 60% gear reduction, plus your choice of cast or billet aluminum housing. Want to go all out? Our dual idler option gives you even more strength. No matter how you ride, there’s a GDP lift built for you.

What Are Dual Idler Gears?

Why do dual idlers matter? Two idler gears spread the load across twice the surface area, making torque transfer more reliable. That means unbeatable durability for your gears. We craft our gears from ultra-tough 9310 steel alloy and CNC precision grind them for a flawless fit. In simple terms, these portals are built to last. Mud, rocks, and nasty trails don’t stand a chance.

Pick the Right Gear Reduction

Your gear reduction choice is key. A lower reduction keeps your top speed higher while still boosting torque. A higher reduction gives you max power but lowers top speed. With 30%, 45%, and 60% options, you can fine-tune your setup for the perfect balance of performance and speed.

Protect Your Drivetrain

With GDP portals, the gear reduction is right in the hub. That means less stress on your transmission, axles, differential, prop shaft, and CVs. Less wear and tear means fewer expensive repairs—your drivetrain will thank you.

GDP Portals Are Built to Take a Beating

We designed GDP portals to be as tough as your RZR. From billet aluminum housings to heavy-duty 5/16” steel alloy backing plates, every piece is made to handle serious abuse. Ride hard and push limits—these portals can take it.

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 idler and drive bearings to maintain perfect gear meshing
