Polaris RZR Trail S 900 6" Portal Gear Lift

You’ve Never Seen Performance Like This
You might think you know what your machine is capable of, but you haven't seen anything until you’ve tried SuperATV’s Polaris RZR Trails S 900 6” Portal Gear Lift. It gives you huge ground clearance and an impressive gear reduction to make your UTV bigger and more powerful than ever. You choose your gear reduction and housing material, or upgrade to dual idlers. With GDP quality, you can’t be stopped.

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.

They’ll Take Your Polaris RZR Trail S 900 Anywhere
No matter how you ride, you’ll never look at your machine the same after installing a set of GDP portals. Whether you stick to mud, trails, dunes, or all of the above, we have the RZR Trail S 900 portals you need. A smaller 30% reduction is perfect for fast rides with plenty of torque. A 45% reduction will let you run bigger tires and take on bigger rocks. And our 60% gear reduction is a must if you want to build the most menacing mud machine imaginable. You could also add to the badass factor by opting for the dual idler gear configuration.

GDP Portals Are Better for Your Drivetrain than Stock
One of the coolest things about portals is the gear reduction that’s built right into the hub. It places less stress on your drivetrain so your axles, prop shaft, differential, and transmission all benefit from it. They work less and you get longer-lasting components.

GDP’s Industry-Leading Strength Is By Design
If you’re not riding on GDP, you’re not riding. A GDP Portal Gear Lift is the best and strongest portal lift on the planet. And you’ve got options, too. Pick from cast or USA-made, CNC-machined 6061 billet aluminum housings. Top-of-the-line housings on top of our 5/16” backing plates make for an unbeatable combination.

• 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
