Polaris RZR S 1000 4" Portal Gear Lift

GDP Gives You The Portals You Need
You’ve never really seen your Polaris RZR S 1000 come alive until you’ve put SuperATV’s 4” GDP Portal Gear Lift on it. It’s available with 15% or 30% gear reductions and cast or billet housings. And for all those riders that can tear up any kit, you can opt for dual idler gears that take durability to another level. Nobody does portals like GDP.

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.

Wherever You Ride, GDP Can Make it Better
GDP has gear reduction options to fit any ride style. Get a 30% gear reduction and start flingin’ mud and crawling over rocks. With a massive boost to torque, you can turn bigger tires that tear through anything. With a 15% gear reduction, you can take on the trail less traveled. You’ll keep that high speed for serpentine tracks but that extra torque will carry you over hills and creeks where others get stuck. Either way, it’s a game changer.

Portals Give You a Longer-Lasting Drivetrain
Portals put the gear reduction right in the hub, which is a literal lifesaver for some of your vehicle’s most critical components. Putting the reduction in the hub places less stress on your axles, differential, prop shaft, and transmission, so you can ride harder than stock while causing less wear. Talk about a win-win situation!

The Beefiest Portals You Can Get
When it comes to all-out durability, nobody does RZR S 1000 portals better than GDP. Our cast and billet aluminum housings are carefully designed from the ground up to address the weak spots we’ve found after years of manufacturing. We combine them with our trail-proven backing plates that are made with an advanced steel alloy that outperforms the competition. In the end, you get the beefiest portals on the market.

• 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
