Create the Ultimate Defender HD10 with GDP Portals
Enhance the performance of your Can-Am Defender HD10 with the SuperATV 6" Portal Gear Lift. The 6" lift combined with gear reduction increases torque and ground clearance while letting you run bigger tires without overloading the drivetrain. Choose between 30%, 45%, or 60% gear reduction based on your riding style. For extra durability, choose the billet aluminum housing instead of the cast housing. For maximum power, go with dual idler portals.
What is a Dual Idler?
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 a stronger gear set. Precision CNC grinding ensures the gears are properly mated, and they are made from 9310 steel alloy.
Dominate Tough Terrain
A 30% reduction provides higher speed while maintaining torque. For larger tires or challenging terrain, a 45% reduction increases torque. For maximum mud performance, a 60% reduction delivers 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.
Built 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.
