If you could get more power and performance from your Polaris RZR Pro S, why would you say no? With SuperATV’s 4” GDP Portal Gear Lift, you get a lift and gear reduction built into one package. Our GDP Portals come in 15% or 30% gear reductions with a choice of either cast or billet aluminum housing. Plus, the 4” lift gives you clearance to tackle bigger obstacles and fit larger tires. You’ll feel the difference every time you hit the gas.
What Is a Dual Idler?
After years of perfecting them, our dual idler gear portals are built for serious strength. The second idler gear helps spread the load for better torque transfer and durability. With precise CNC grinding and tough 9310 steel, these gears are made to last. Perfect engineering and precision mean our dual idlers are the game changer you’ve been waiting for.
Gear Reduction for Peak Performance
Choose a gear reduction that fits your ride. Go with a 15% reduction for faster speeds and solid torque, or ramp it up to 30% for bigger tires and tackling rougher trails. It’s the perfect way to customize your machine to match your style.
Reduce Wear on Your Drivetrain
GDP Portals for the Polaris RZR Pro S give you a lift and gear reduction right at the wheel hub. This setup helps protect your drivetrain and keeps your axles at factory angles, which reduces wear and tear on your CVs for a more durable ride.
The Strongest Portals on the Market
The last thing you need when you’re out in your Polaris RZR Pro S is a breakdown. That’s why we designed our cast and 6061 billet aluminum housing to handle tough conditions. They’re backed by our advanced steel backing plates for unmatched strength.
- Our housings are reinforced for gear retention and optimized for oil flow
- Advanced steel alloy backing plates are stronger than chromoly
- 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
