Transform Your Teryx H2 with GDP Portals
Give your Kawasaki Teryx H2 the muscle it needs with SuperATV’s 4” GDP Portal Gear Lift. This kit combines extra ground clearance with a gear reduction for a major performance upgrade. Choose a 15% or 30% gear reduction with a billet housing. With dual-idler gears to maximize durability, you’ll have the strength to dominate difficult trails and clear up to 40” tires.
What Is Dual Idler?
Perfection takes time. After years of research and development, SuperATV has made its 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 these do. The 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.
Choose the Right Gear Reduction
The right gear reduction can change how your machine handles on the trail. The 15% option delivers plenty of torque without sacrificing higher speeds. Choose the 30% gear reduction if you want to turn bigger tires and power across more demanding terrain.
Reduce Drivetrain Stress
GDP Portals place the gear reduction at the hubs instead of inside your transmission. This design reduces stress on your axles, prop shaft, differential, and transmission. You get the extra torque you need without putting unnecessary wear on your Kawasaki Teryx H2’s drivetrain.
Built for Extreme Strength
Your Kawasaki Teryx H2 packs serious power, so SuperATV built these portals to take the pressure. You can choose cast or billet aluminum housings to match your riding style. Advanced steel alloy backing plates complete the setup and deliver outstanding durability.
The 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—SuperATV knows because it tested them

The portals use:
Advanced gaskets and O-rings with excellent oil resistance and low deterioration rates
A sealed input gear and double-lipped output seal
