Dominate Every Trail — SuperATV GDP Portal Gear Lift for the Can-Am Defender HD11

Take your Can-Am Defender HD11 to the next level with the SuperATV GDP (Gear Drive Portal) Portal Gear Lift — the most complete lift and torque upgrade available for the 2026+ Defender HD11, offered in both 4-inch and 6-inch lift heights for 2 Door and 4 Door MAX models.

Whether you're crawling through deep mud, scaling rocky terrain, or running oversized tires on wide-open trails, these portal gear lifts deliver the clearance and low-end power your Defender needs to perform without limits.

Choose Your Lift — 4" or 6" Portal Gear Lift

4" Portal Gear Lift — The perfect balance of ground clearance and performance for riders who want a meaningful upgrade without going full extreme. Pairs with a 15% or 30% gear reduction to suit trail riding, mudding, or daily utility work.

6" Portal Gear Lift — Maximum clearance for maximum terrain. Built for riders who run the biggest tires and push into the gnarliest conditions. Pairs with a 30% or 45% gear reduction, putting serious torque at the wheels when you need it most.

Both options are available in your choice of cast aluminum or premium 6061 billet aluminum housings, and fit both the 2 Door and 4 Door MAX Defender HD11 configurations.

Lift AND Torque — More Than Just Added Height

Unlike traditional lift kits that only raise your machine, SuperATV's GDP portals combine ground clearance with a real gear reduction at the wheel hub. That means more torque, more control, and less strain on your drivetrain — all in a single bolt-on kit.

The gear reduction is relocated to the wheel hub rather than the transmission, protecting your axles, differential, prop shaft, and CVT from added stress. Your factory suspension geometry stays intact, keeping your CV joints running cooler and lasting longer.

Built to Last in the Worst Conditions

Every GDP portal is engineered for serious abuse:

• Precision-ground 9310 alloy billet steel gears — run cool and quiet, even under extreme load
• 1.5" diameter 4340 hardened steel drive shaft for maximum strength
• 6061 billet or cast aluminum housings reinforced with steel alloy backing plates
• No-leak bearings and seals for long-term reliability
• Universal hub design compatible with all major bolt patterns
• Backed by a Limited Lifetime Warranty from SuperATV
