Can-Am Defender HD10 4" Portal Gear Lift

Take Your HD10 to the Next Level with GDP Portals
Boost your Can-Am Defender HD10 with SuperATV’s 6” Portal Gear Lift. You’ll get 6” of lift, more torque, and the clearance to run bigger tires. Pick a 15% or 30% gear reduction, depending on your riding style. And for maximum strength, upgrade from cast to billet aluminum housing. To really take it to the next level, upgrade to our dual idler gears.

What Is a Dual Idler?
Perfection doesn’t happen overnight. That’s why our dual idler gear portals are built differently. By adding a second idler gear in the portal box, the load spreads over more surface area, giving you more reliable torque transfer and a stronger gear set overall. Of course, two gears are useless if they don’t mesh perfectly—that’s why we use precision CNC grinding and ultra-strong 9310 steel.

Tough Enough for Any Terrain
GDP Portal Gear Lifts are made for every riding style. Dunes, mud, trails, or work—there’s a setup that fits. Choose a 15% gear reduction for speed or a 30% for max torque and big tires. Add dual idler gears for serious strength that can handle whatever you throw at it.

Portals Protect Your Drivetrain
Instead of forcing the entire drivetrain to handle the burden of turning massive tires, GDP portals handle gear reduction at the hub. This significantly reduces wear on important parts such as your axles, differential, prop shaft, and transmission.

Built Tough with Aluminum and Steel
When things get rough, these portals keep going. The cast and billet aluminum housings are built strong, and the advanced steel alloy backing plates back them up with serious durability.

• 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 a Frame Stiffener
While portals and big tires boost performance, they can increase stress on your frame. Make your suspension rock-solid by pairing your new HD10 portals with a SuperATV Frame Stiffener.
