Transform Your Can-Am Defender HD11 Into an Unstoppable Beast

Ready to dominate every trail, conquer muddy terrain, and tackle rocky obstacles with confidence? The SuperATV 4" Portal Gear Lift is the ultimate all-in-one upgrade that delivers massive ground clearance and crushing torque without compromising your drivetrain.

Lift + Power in a Single Package

Unlike traditional lift kits that only raise your machine, this portal gear lift gives you 4 inches of ground clearance while simultaneously adding a selectable gear reduction. Choose between 15% or 30% gear reduction to match your riding style—whether you're blazing fast trails or crawling through deep mud with oversized tires.

Built Fortress-Tough for Extreme Terrain

Engineered with precision-ground 9310 billet steel alloy gears that stay cool and run whisper-quiet even under extreme abuse. Select from durable cast or premium 6061 billet aluminum housings reinforced with beefy steel alloy backing plates for unbeatable strength and reliability.

Protect Your Investment

GDP Portals relocate the gear reduction to the wheel hub—not your transmission. This revolutionary design shields your axles, differential, prop shaft, and transmission from costly stress and premature wear. Your factory suspension geometry stays intact, keeping CV joints running cool and extending component life.

• (4) Fully assembled portal hubs with 9310 gears, seals, output shaft, advanced gaskets, and thrust bearings
