Gen 3 Portals for Your ride
Take your ride from bargain-rate buggy to the undisputed king of the trail with SuperATV's first-of-its-kind 4" Portal Gear Lift. Choose from 15% or 30% gear reductions and billet or cast aluminum housings to get the most out of your side-by-side.

• Gives you a 4" lift and a gear reduction in one package
• Choose a 15% or 30% gear reduction
• Maintains OEM suspension angles

Choose a 15% or 30% Gear Reduction
Get extra torque and better acceleration on rough terrain with GDP Portals. The 30% gear reduction is made to crank oversized tires in deep mud. If you don't want to totally sacrifice your top speed, opt for a 15% gear reduction and you'll still get tons of low-end torque. Portals give you the power you need to dominate any terrain with confidence.

GDP Portals Protect Your Drivetrain
GDP Portals put the gear reduction at the end of your drivetrain—in the wheel hub. This protects your axles, prop shaft, differential, and transmission from unnecessary stress. Because you're not overworking your drivetrain components, these portals prevent costly repairs.

Steel Alloy Gears
We use precision-ground 9310 billet steel alloy gears in our portals. The durable steel construction can withstand all types of abuse. Our gears are designed to stay cool and run quietly even when you're stomping on the gas.

Built to Last
When you're way off the beaten path, you can't compromise on reliability. That's why we use cast or 6061 billet aluminum housings. Combined with the beefy steel alloy backing plates, they deliver unbeatable performance and strength. No matter where your ride goes, GDP Portals are ready to take you there.

• 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

Bolster Your UTV with a Frame Stiffener
Big portals and big tires can make everything, well, big. Make sure your stock frame can keep up by adding a SuperATV Frame Stiffener when you install your new portals. It'll give you the confidence to keep the pedal down.
