Turn Your Defender HD9 into a Powerhouse with GDP Portals
Take your Can-Am Defender HD9 to the next level with SuperATV’s 6” Portal Gear Lift. With 6” of lift and built-in gear reduction, you’ll get improved torque, better ground clearance, and the freedom to run larger tires safely. Pick a 30%, 45% or 60% gear reduction to suit your terrain, and for extra strength, upgrade from cast to billet aluminum housing. Still worried you won’t have enough power? Our dual idler portals are a serious game changer.
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.
Ride on any Terrain
Your ride feel can change with a gear reduction. Go with 30% if you want quicker speeds without losing torque. If your tires are bigger and the trails are rough, 45% gives you the boost and control you need to handle it all. Build the supreme off-road beast with a 60% gear reduction, then amplify its strength using dual idler gears.
Less Strain on Your Drivetrain
With GDP Portals, the gear reduction is in the wheel hubs, not inside the transmission. That means your Defender HD9’s drivetrain takes less strain. Your axles, driveshaft, differential, and transmission all work easier, which cuts down on wear and avoids expensive fixes.
Unparalleled Strength
Nobody wants to keep replacing parts. Our GDP Portals are built tough with cast or billet aluminum housing and 5/16” backing plates made from advanced steel alloy. They can handle serious abuse—and with a lifetime warranty, you get peace of mind too.
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
- Add an Unbeatable Frame Stiffener
While portals and huge tires make adventures more exciting, they can also challenge your frame. Protect your suspension by adding a SuperATV Frame Stiffener today.
