Polaris RZR Turbo R 4" Portal Gear Lift

Top of the Industry—GDP Portals
Give your Polaris RZR Turbo R the extra lift it needs by installing SuperATV’s GDP 4” Portal Gear Lift. It delivers the height you’ve been looking for and gives you the torque you need to dominate the trails. And because every rider rides differently, we designed them with a 15% or 30% gear reduction, your own choice of housing style, and the option for dual idler gears. With all the options, you’re sure to choose the perfect portal gear lift for your rig.

What Is a Dual Idler?
Perfection is a process—and after years of research and development, our dual idler gear portals are unlike anything you’ve seen before. 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. That’s why we use precision CNC grinding and make our gears from ultra-strong 9310 steel alloy.

Get a Gear Reduction to Match Your Style
Pick a gear reduction that matches your style—choose a smaller 15% reduction for faster rides and plenty of torque. Or you can add bigger tires and take on rougher rides with a bigger gear reduction—like 30%. It’s the best way to customize your rig.

GDP’s Gear Reduction Reduces Drivetrain Wear
We love that portal gear lifts put the gear reduction directly in the hub. This leads to less stress on your machine’s most vital parts, even through rough riding. Your axles, differential, prop shaft, and transmission will thank you—and they’ll last longer, too.

Smartly Designed, Trail-Proven Strength
”Compromise” isn’t in our vocabulary. GDP is built to last from the smallest bolt to the industry-leading gears. That’s why they’re the strongest portal gear lifts on the planet. Our cast and billet aluminum housings are the thicker and more reliable. Combine that with 5/16” backing plates made from an advanced steel alloy, and our RZR Turbo R portals are unstoppable. If you want ultimate strength, this is 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
