Enhance Your Ride with GDP Portals
Looking to get more out of your ride? SuperATV's 6" Portal Gear Lift gives you 6" of lift and built-in gear reduction for extra torque, better clearance, and the ability to run bigger tires without stressing your ride. You can pick 30%, 45%, or 60% gear reduction depending on how you like to ride, and if you want it really tough, go with the billet aluminum housing over cast housing. For maximum strength upgrade to our dual idler configuration.

What Is a Dual Idler?
We've spent years perfecting our dual idler gear portals. Adding a second idler gear spreads the load over more surface area, giving you more reliable torque and a super-strong gear set. But it's all about fit—so we precision grind every gear from 9310 steel for perfect mesh.

Tackle Tough Trails
Choosing the right gear reduction is the most important thing when getting portals. A 30% gear reduction gives you faster speeds and solid torque, while a 45% reduction is perfect for bigger tires and tough trails, giving you the extra power and control to dominate any terrain. Create the ultimate mud powerhouse with a 60% reduction in gearing, and unleash extra force with dual idler gears.

No Stress on Your Drivetrain
GDP Portals shift gear reduction to the wheel hubs, taking the pressure off your drivetrain. Less strain on your axles, driveshaft, differential, and transmission means less wear and fewer expensive repairs down the road.

Strength that Can't Be Beat
Our GDP Portals are built to take a beating. You can choose from cast or billet aluminum housing with rugged 5/16" steel alloy backing plates. Ready for abuse and backed by a lifetime warranty, they're engineered to last.

• 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

Don't Forget a Frame Stiffener
Portals and oversized tires deliver serious fun, but they also put extra strain on your machine's frame. Strengthen your suspension setup by adding a SuperATV Frame Stiffener when installing your new portals.
