Make Your RZR a Mud Monster
If you want the ultimate mud-conquering upgrade, you need SuperATV's Polaris RZR XP 8" Portal Gear Lift. It gives you the clearance, power, and performance to conquer even the thickest mud with ease. You can choose a 45%, 60%, or 70% gear reduction and choose between a billet or cast aluminum housing to turn your RZR into the best mud machine on the planet.

What’s 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.

Pick What You Want with 45%, 60%, and 70% Gear Reductions
Putting big tires on your RZR XP looks cool, and they make every mud pit easier to rip through. GDP Portals not only give you room for up to 40” tires on your RZR XP but also come with a 45%, 60%, or 70% gear reduction to boost your torque. Boosted torque means more power, and more power means you can turn massive tires almost like they’re as light as stock.

Protect Your Drive Train
With portals, the gear reduction sits right in the hub, meaning your drivetrain doesn't have to work as hard to turn those large tires. That’s good news for your axles, differential, prop shaft, and transmission. They’ll wear less and last longer.

Housings and Backing Plates Built Tough
Our GDP Portals are built to withstand the roughest rides you can give them. Whether you choose cast or 6061 billet aluminum housings, you'll benefit from awesome durability thanks to our proven design. Add in the 5/16” backing plates made from advanced steel alloy, and you've got the sturdiest portals in the industry—your RZR XP deserves nothing but the best.
