SuperATV - Can-Am Defender / Defender MAX HD7-HD10 8" Portal Gear Lift

Your Defender HD10 Will Become Unstoppable

Your Can-Am Defender HD10 is a powerhouse, but SuperATV's 8" GDP Portals unlock its full potential. This premium upgrade combines an 8-inch lift with a built-in gear reduction to deliver more torque, better clearance, and enhanced off-road capability. Whether you're hauling, climbing, or cruising, you'll benefit from the ability to run larger tires with ease. Customize your ride with 45%, 60%, or 70% gear reduction options and select either billet or cast housings for maximum durability.

What is a Dual Idler?

After years of research and development, SuperATV's dual idler gear portals are 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 available. Precision CNC grinding ensures perfect mating. Gears are made from the industry's toughest 9310 steel alloy.

You'll Be Able to Take on Any Terrain

The standout feature of the Defender HD10 8" GDP Portals is the ability to fine-tune your ride. With your choice of 45%, 60%, or 70% gear reduction, you can decide how much torque and speed your machine delivers. Both configurations provide impressive performance, giving you the strength to tackle rock gardens, confidently spin larger tires, and maintain control when pushing through deep mud.

A Gear Reduction That Protects Your Drivetrain

GDP Portals shift the gear reduction from the transmission to the wheel hub, creating a more efficient drivetrain. This setup minimizes the load placed on vital components like your axles, prop shaft, differential, and transmission. Less strain means better durability and a reduced chance of costly repairs.

Unbeatable Strength

Strength is non-negotiable when it comes to your Defender HD10. SuperATV's GDP Portals are built with your choice of cast or billet aluminum housings and rugged 5/16" steel alloy backing plates for top-tier durability. These portals are designed to endure aggressive riding and heavy workloads. A lifetime warranty covers your investment.
