Revamp Your Ride with GDP Portals
Turn your ride into a powerhouse with SuperATV's 6" GDP Portal Gear Lift. These portals are the strongest, most trusted in the industry. With a built-in gear reduction and a full 6" lift, they give your ride more torque, clearance, and the ability to run massive tires. You can pick a 30% or 45% gear reduction, and for maximum strength, upgrade from cast to billet aluminum portal housings.

Built for Extreme Terrain
Whether you're tackling mud pits, rock gardens, or steep trails, our portals deliver the performance you need. The 30% gear reduction boosts your torque without killing top speed—perfect a balanced performance profile. If you're serious about running oversized tires and crushing mud or rocks, go with the 45% gear reduction for unstoppable pulling power and acceleration.

Protect Your Drivetrain
Unlike gear reductions in the transmission, GDP Portals move the reduction to the hub. That takes stress off your axles, prop shaft, differential, and transmission—you can push your ride harder without worrying about premature drivetrain wear. Less strain means more durability and fewer costly repairs.

Strength That Lasts
Every set of GDP Portals is built to handle the toughest rides. Choose between cast or 6061 billet aluminum portal housings paired with 5/16" advanced steel alloy backing plates. With this level of strength and engineering, you're getting the most reliable portal gear lift 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
