Gear Down and Go Big
SuperATV’s GDP 8” Portal Gear Lift for the Polaris RZR XP Turbo is geared down so you can go big. It gives you a lift and a 45% or 60% gear reduction in one box. Want the most extreme? Opt for a 70% gear reduction complete with dual idler gears for the most balls to the wall portals on the market. Get the clearance to run bigger tires and the torque you need to turn them. With huge clearance, huge torque, and optional billet aluminum housings, you can install monster tires to take on any challenge.

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.

45%, 60%, and 70% Gear Reductions Destroy Mud
With 8” portals and your choice of 45%, 60%, or 70% gear reductions, you get clearance for huge tires and a massive boost in torque. It’ll turn monster tires like they’re stock. There’s nothing that can stop our 8” portals. The challenge isn’t rolling through mud—it’s finding mud holes deep enough for your new mud monster.

A Gear Reduction That Protects Your Drivetrain
Portals put the gear reduction right in the hub. That puts it after your entire drivetrain and it makes your drivetrain work less and wear less. That means more miles out of your axles, differential, transmission, and prop shafts.

 about how tire size and gear reduction can unleash your machine’s potential.

Stronger Housings and Backing Plates
GDP Portals are the strongest you can get because we know how to make them tough. We’ve been using them and refining them for years. Whether you go with cast or USA-made, 6061 billet aluminum housings (which look awesome), you’ll get unmatched strength through superior design. Combine that with 5/16” backing plates made with an advanced steel alloy, and you’ve got the brawniest portals on the market.

• Our housings are reinforced for gear retention and optimized for oil flow
• Advanced steel alloy backing plates are stronger than chromoly
• Enhance with —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
