Can-Am Defender HD10 6" Portal Gear Lift

Create the Ultimate Defender HD10 with GDP Portals
Enhance the performance of your Can-Am Defender HD7 with the SuperATV 6” Portal Gear Lift. Its 6” lift combined with a gear reduction increases torque and ground clearance while letting you run bigger tires without overloading the drivetrain. You can choose between 30%, 45%, or 60% gear reduction based on your riding style. For riders seeking extra durability, choose the billet aluminum housing instead of the cast housing. For maximum power, go with our dual idler portals.

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.

Dominate Tough Terrain
A gear reduction directly affects performance. A 30% reduction provides higher speed while maintaining torque. For larger tires or challenging terrain, a 45% reduction increases torque, helping you conquer demanding conditions. Create the ultimate mud powerhouse with a 60% reduction in gearing, and unleash extra force with dual idler gears.

Doesn’t Wear Out Your Drivetrain
GDP Portals move the gear reduction from the transmission to the wheel hubs, decreasing the load on your Defender HD10’s drivetrain. By reducing stress on axles, driveshaft, differential, and transmission, they help minimize wear and prevent costly mechanical issues over time.

You Can’t Beat GDP
GDP Portals are engineered to last. Choose between cast or billet aluminum housings, paired with 5/16” heavy-duty backing plates crafted from advanced steel alloy. This setup is built to endure demanding conditions and comes with a lifetime warranty for added security.

• 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
