Can-Am Defender HD7 8" Portal Gear Lift — Single / No, I do not have a Big Lift Kit.

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?
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.

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, the choice is yours. Either way, 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 down the road.

Built for Battle
When you invest in upgrades, durability matters. That’s why 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. Push your machine without hesitation—these portals are built for it. And with a lifetime warranty included, you’re covered when the unexpected happens.

• 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
Adding an 8” portal lift and larger tires to your Can-Am Defender HD7 is a great way to boost performance, but it also increases stress on your frame. To keep everything solid under pressure, SuperATV’s Frame Stiffener is a must-have. It reinforces key areas to help prevent bending or warping, so your machine stays strong no matter how hard you ride.
