Polaris RZR Trail S 1000 6" Portal Gear Lift

GDP’s RZR Trail S 1000 Portals Are the Industry’s Best
Give your Polaris RZR Trail S 1000 a complete overhaul with a GDP 6” Portal Gear Lift from SuperATV. It delivers impressive height and all the torque you need to dominate the trails. We didn’t design these portals for one rider—we designed them for all riders. By choosing 30%, 45%, or 60% gear reduction, and your housing style, you’re getting a portal gear lift that’s entirely your own. You can even take things to the extreme when you upgrade to dual idler gears for maximum strength.

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.

Get a Gear Reduction to Match Your Style
You never know where adventure will lead, and sometimes your next ride takes you to unexpected places. GDP is built with wild adventure in mind, from trails to dunes to mud. Whether you’re climbing cliffs in Moab or exploring your property, a GDP Portal Gear Lift will enhance your ride. Get a smaller 30% reduction for faster rides that still pack plenty of torque. Bigger tires for rocks or rough rides require a bigger gear reduction—like 45%. Build the mother of all mudders with a 60% gear reduction. Then take your strength over the top with dual idler gears. Portals give you your torque back so your monster build can still rip harder than the rest.

GDP’s Gear Reduction Reduces Drivetrain Wear
We love that portal gear lifts put the gear reduction directly in the hub. This leads to less stress on your machine’s most vital parts, even through rough riding. Your axles, differential, prop shaft, and transmission will thank you—and they’ll last longer, too.

Smartly Designed, Trail-Proven Strength
”Compromise” isn’t in our vocabulary. GDP is built to last from the smallest bolt to the industry-leading gears. They’re the strongest portal gear lifts on the planet. Our cast and billet aluminum housings are the thickest and most reliable on the market. Combine that with 5/16” backing plates made from an advanced steel alloy, and our RZR Trail S 1000 portals are unstoppable. If you want ultimate strength, this is it.

• 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
