SuperATV POLARIS RZR XP TURBO S 4" PORTAL GEAR LIFT Single Idler Only
Dominance Is Spelled “GDP”
The best, toughest, and most reliable portal lifts only come from GDP. So upgrade to SuperATV’s GDP 4” Portal Gear Lift for your Polaris RZR XP Turbo S to get a lift and a gear reduction in one box. Get the clearance to run bigger tires and the torque you need to turn them. The lift and gear reduction are in the hub, which means they maintain suspension geometry and reduce drivetrain stress. Our 4” portal lift is available with 15% or 30% gear reductions and cast or billet housings. And you can opt for dual idler gears to get unbeatable strength. No matter how you ride or how much you tear your stuff up, GDP is for you.
What is a Dual Idler®?
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.
Get the Right Gear Reduction to Dominate Any Terrain
No matter what type of riding you do, we’ve got a gear reduction that will make you better at it. If your favorite ride is through deep mud or all over killer rock gardens, get a 30% gear reduction. It gives you more torque so you can turn bigger tires through all sorts of crazy terrain. Want to hit top speed with tires that aren’t as huge? Stick with a 15% gear reduction. It still gives you enough torque to make you grin, but saves more of your top-end speed.
GDP’s Gear Reduction Protects Your Drivetrain
GDP puts the gear reduction right in the hub. Because that’s right at the end of your drivetrain, all your components benefit from it the same way you do. With GDP Portals, your axles, differential, prop shafts, and transmission all work less and wear less than with stock.
Strength Worthy of Your RZR Turbo S
Try as you might, you won’t find portals stronger than GDP. Our cast and billet aluminum housings are smarter, stronger, and more reliable. We pair them with 5/16” backing plates that use a special steel alloy that’s incredibly strong. Together, they make an unbeatable pair that’s tough enough for you to send 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
Complete the Package with a Frame Stiffener
RZR Turbo S portals with monster tires are fun, but they can place additional stress on your machine’s frame. To make your UTV stronger than ever, add a SuperATV Frame Stiffener when you check out!
