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

The Ultimate Enhancement for Your Defender HD7

Your Can-Am Defender HD7 is a dependable machine for getting the job done, but it can do even more with the right upgrade. SuperATV's 8" GDP Portals take your ride to the next level by adding serious capability. With 8 inches of lift and an integrated gear reduction, you'll gain extra torque, improved ground clearance, and the freedom to run bigger tires. Pick from 45%, 60% or 70% gear reductions and choose a billet or cast housing to match your needs.

What is a Dual Idler?

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. Precision CNC grinding ensures perfect mating. Our gears are made from the industry's toughest 9310 steel alloy.

Tackle any Terrain

One of the biggest advantages of our Defender HD7 8" GDP Portals is the ability to match your setup to the way you ride. With 45%, 60%, and 70% gear reduction options, you can dial in the perfect balance of torque and speed. Whether you're looking for extra pulling power or a more controlled ride, you'll have what it takes to crawl over rocks, turn larger tires without hesitation, and power through thick mud without losing momentum.

Less Stress on Your Drivetrain

GDP Portals relocate the gear reduction to the wheel hub instead of keeping it in the transmission, giving your Defender HD7 a smarter, more durable setup. By moving that stress outward, key drivetrain components like your axles, prop shaft, differential, and transmission don't have to work as hard. The result is less wear over time and a lower risk of expensive breakdowns.

Built for Battle

When you invest in upgrades, durability matters. SuperATV's GDP Portals for your Defender HD7 are built to take a beating. You can choose between cast or billet aluminum housings, both designed for serious strength. Pair that with 5/16" backing plates made from an advanced steel alloy, and you've got a setup that's ready for hard use. These portals come with a lifetime warranty.

• 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
• No vents because vents do more harm than good
