GDP Portals Are Perfect
Get the power and performance you crave with SuperATV's GDP 4" Portal Gear Lift. These portals are available with 15% or 30% gear reductions. That means you get exactly what you need to make work easier and weekends more fun. Plus, you can upgrade to billet aluminum housings and dual-idler gears for ultimate reliability and 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.

Great for Any Use
Any rider can benefit from GDP Portals with your choice of gear reduction. Get a 30% to run on wilder terrain like mud or rocks. Stick with 15% to improve your trail riding and hauling capabilities. Either way, you'll have plenty of punchy torque that will put a grin on your face.

A Gear Reduction That Protects Your Drivetrain
With portal lifts, the gear reduction is placed in the hub instead of in the transmission. This means your drivetrain doesn't have to work as hard, so those important components will last longer. Of all the benefits of a portal gear lift, reduced stress on your axles, differential, prop shaft, and transmission is definitely at the top of the list.

Stronger Portals All Around
We know what makes a portal break and what doesn't. Whether you choose cast aluminum housings or 6061 billet aluminum, they come paired with our unstoppable advanced steel alloy backing plates. GDP portals are built with the best experience and materials so you can ride with confidence.

• 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
