Polaris RZR XP Turbo S 6" Portal Gear Lift

GDP’s Polaris Turbo S Portals Are the Industry’s Best

You don’t know what you’ve been missing—hitting the trail with GDP’s power and capability on your UTV is the best way to ride. So get a complete performance overhaul with SuperATV’s GDP 6” Portal Gear Lift for the Polaris RZR XP Turbo S. Customize by choosing between a 30%, 45%, or 60% gear reduction and selecting a cast or billet aluminum housing. You can also take your strength over the top by upgrading to SuperATV's dual idler configuration. No matter how you ride, GDP can make it better.

What is a Dual Idler®?

Perfection takes time. After years of research and development, SuperATV has made its 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 these do. The 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.

Different Gear Reductions For Different Ride Styles

You can choose between 30%, 45%, and 60% gear reductions. Match your gear reduction to the way you ride for perfectly balanced power and speed. If you like to hit the gas and fly on the trails, go with 30%. For mud and rocks, go with 45%. If you’re rocking massive tires and want to make sure you always come out of the bounty hole first, go with the maximum 60% gear reduction.

GDP Portals Put Less Strain on Your Drivetrain

GDP Portals give you a gear reduction in the hub instead of the transmission. This reduces the wear and tear on your axles, differential, prop shaft, and transmission. Portals also maintain factory suspension geometry to keep your CVs happy and cool. Your RZR’s most vital parts will last longer.

GDP Is Built to Be the Strongest

These RZR XP Turbo S portals are built for hard rides and tons of fun. That’s why everything from the billet housings to the advanced 5/16” steel alloy backing plates are designed to be as strong as possible. Push them to the limit—that’s what they’re for.

The 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—SuperATV knows because it tested them

Advanced Gaskets, Seals, and Bearings

The 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

Reinforce Your Frame with a Frame Stiffener

SuperATV highly recommends running a SuperATV Frame Stiffener with your 6" Portal Gear Lift. The stock frame just doesn't have what it takes. A frame stiffener reinforces your frame enough to let you ride your 6" portals with monster tires and no worries.
