Gen 3 Portals Are Geared for All
Your RZR Pro XP isn’t built for just one kind of rider—you can take it through mountains or mud or dunes. That’s why SuperATV’s GDP 6” Portal Gear Lift lets you choose between 30%, 45%, or 60% gear reductions. Gear down and get the torque you need to match your ride style and your tire size. Then go big and opt for dual idler gears if you want ultimate strength. GDP means you get to ride your way—and have a lot more fun while you do it.
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.
Perfect for Mud
You can’t go to a mud park in America without coming across a set of portals. That’s for good reason—portals and mud go together like peanut butter and jelly. The deeper you go, the more you’ll notice the torque from your gear reduction. And that 6” lift will keep you from getting swamped.
A Gear Reduction That Protects Your Drivetrain
With the gear reduction all the way at the hub, you get reduced stress on your axles, differential, prop shaft, and transmission. That means your components will last longer than stock even though you’re riding harder.
Stronger Housings and Backing Plates
We’ve spent years tweaking and honing our portal housings to make them as strong as possible. And we combine them with advanced steel alloy backing plates. With tens of thousands of housings in the wild Proving their strength every weekend, you know you’re getting the best. So go with cast or super-sleek, USA-made billet aluminum.
Advanced Gaskets, Seals, and Bearings
Our portals use:
Complete the Package with a Frame Stiffener
Portals and monster tires are fun, but they can place additional stress on your machine’s frame. To make your suspension bulletproof, don’t forget to add a SuperATV Frame Stiffener when you check out!

- 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
