GDP Portals Rock

The temptation to drown your stock RZR in a mud pit is almost irresistible, but you’re worried about getting stuck. Get SuperATV’s Polaris RZR Pro R 4" Portal Gear Lift so you can take on the bounty hole without batting an eyelash. You get your choice of a 15% or 30% gear reduction and cast or billet aluminum housing—oh, and don’t forget the dual idler gears option. We built these portals to get you through even the slickest, deepest mud with ease.

Dual Idler Gears?

Perfection doesn’t happen overnight. We dedicated years of research and development to make our dual idler gear portals unlike anything you’ve ever seen before. Adding a second gear in the portal box spreads the force over twice as much surface area for better, more reliable torque transfer. But these aren’t any old dual idler gears. We use precision CNC grinding to ensure a perfect fit. We use industry-leading 9310 steel alloy for quality and durability too. They’re the strongest gear set you can get.

Pick Your Gear Reduction

We let you choose your gear reduction to customize your ride down to the smallest detail. A 15% gear reduction is perfect for adding strength for the occasional mud pit while preserving your rig’s top speed. If you want to add huge tires, a 30% gear reduction will help you get the power you need to keep those monsters turning. No matter how you ride, we’ve got the perfect gear reduction for your Pro R.

Protect Your Drivetrain with GDP

Because the gear reduction is located in the wheel hub, our GDP portals protect the more expensive drivetrain parts from unnecessary stress. GDP portals work overtime to save those parts—like your axles, differential, prop shaft, and transmission—from all the stress required to move giant tires.

Built Tough with Aluminum and Steel

We built these portals to last. Our cast and billet aluminum housings are designed for maximum durability even under the worst abuse. We pair our housings with advanced steel alloy backing plates to make them completely matchless in strength and quality.

• 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
