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?

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. Didn’t think dual idlers mattered? With GDP’s quality and experience, they finally do.

You’ll Be Able to Take on Any Terrain

The standout feature of our 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. It’s power and versatility built around you.

A Gear Reduction That Protects Your Drivetrain

On your Defender HD10, 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 in the future.

Unbeatable Strength

Strength is non-negotiable when it comes to your Defender HD10, and SuperATV’s GDP Portals are built to exceed expectations. With your choice of cast or billet aluminum housings and rugged 5/16” steel alloy backing plates, you’re getting top-tier durability from every angle. These portals are designed to endure aggressive riding and heavy workloads alike. And thanks to a lifetime warranty, you can ride with confidence knowing you’re covered if something goes wrong.

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

Frame Stiffener Required

When you outfit your Can-Am Defender HD10 with an 8” portal lift and larger tires, you’re increasing both performance and frame load. SuperATV’s Frame Stiffener is the solution for maintaining structural integrity. It strengthens your frame to resist bending and ensures your machine is ready for demanding rides and heavy workloads.
