Gen 3 Portals Are a Game Changer

The Polaris RZR RS1 is a pretty stand-out machine on its own, but have you seen what one of these things can do with some extra ground clearance and power behind it? Adding SuperATV’s GDP 6” Portal Gear Lift to your ride is a no-brainer if you want to turn heads wherever you go. GDP didn’t make the first side-by-side portal kit on the market—just the first kit anyone gave a damn about. Choose between a 30% or 45% gear reduction. Count on SuperATV to totally redefine the RZR as you know it.

Any Rider, Any Terrain Type

It doesn’t matter where, when, or how you ride—we guarantee a GDP Portal Gear Lift will make your experience better. Go with a smaller 30% gear reduction to harness speed and plenty of torque. Upgrade to bigger tires and take on rougher terrain with a 45% reduction. From the trails to the dunes and everything in between, GDP portals give you your torque back and make sure nothing will slow you down.

Longer-Lasting Components

These 6” portals aren’t just good for your ride experience—they’re great for your drivetrain, too. The gear reduction is placed in the hub, meaning there’s less strain put on your axles, prop shaft, differential, and transmission. You’re getting a lifted ride, more torque, and longer-lasting components. It’s a win-win.

Premium Materials Backed by Unmatched Experience

If it doesn’t say GDP, you don’t want it. GDP portals represent the best and strongest portal gear lifts on the planet. They’re available in cast and billet aluminum housings, both made from the thickest and strongest material you can get. And they all feature 5/16” backing plates made from an advanced steel alloy. Top-notch materials combined with industry-leading expertise makes for a set of RZR portals that are unstoppable.

Our housings are reinforced for gear retention and optimized for oil flow
Advanced steel alloy backing plates are stronger than chromoly
Ultra-strong integrated rear hub backing plates—no more failure-prone aluminum hubs
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

Get Extra Reinforcement with a Frame Stiffener

Rough riding and added weight can wreak havoc on your RZR’s frame if it’s not properly reinforced. That’s why we strongly recommend adding a SuperATV Frame Stiffener when installing your new portals. It adds all the support you need to tackle hard rides in confidence.
