Description

Take your build to the next level with the SuperATV 4” Portal Gear Lift for the Can-Am Defender HD11. Designed for riders who demand more ground clearance, more torque, and more durability, this GDP (Gear Driven Performance) system delivers 4 inches of lift combined with integrated gear reduction at the hub.

Unlike traditional lift kits, GDP portals relocate the gear reduction to the wheel hub. That means added torque and reduced strain on your drivetrain. Axles, differentials, prop shafts, and your transmission are protected from the excessive stress that comes with oversized tires. The result is a stronger, smarter upgrade that transforms how your Defender performs.

Choose the setup that matches your riding style. A 15% gear reduction is ideal for faster trail riding and aggressive terrain. Step up to 30% reduction for maximum torque, mud builds, heavy work applications, and turning massive tires with confidence. With 4 inches of lift, you gain serious ground clearance and the ability to run up to 32” tires on a stock suspension setup.

Built for extreme use, these portals feature thick cast or billet aluminum housings engineered for superior strength and optimized oil flow. Reinforced for gear retention and durability, they’re paired with 5/16” advanced steel alloy backing plates that outperform traditional chromoly. There are no unnecessary vents—because they were tested and proven to do more harm than good.

Inside, premium components ensure long-term reliability. Advanced gaskets and O-rings provide excellent oil resistance. A sealed input gear, double-lipped output seal, and full sealing coverage help eliminate leaks. Double-angular contact output bearings prevent premature wear, while roller idler and drive bearings maintain precise gear meshing under load.

4” Portal Gear Lift Kit Includes:

(4) Assembled portal hub boxes with 9310 gears, seals, output shaft, Thermo-Tork® gaskets, and thrust bearings
(4) Universal hubs and stainless steel slotted rotors with lugs
(4) Specialized steel alloy backing plates
(4) Steel caliper mounting plates
(6) Steel sleeves
(12) Bushings

Max Tire Size Recommendation (4” Portals):

32” tires on stock suspension

For riders adding portals and oversized tires, reinforcing your chassis is critical. Pair your install with a SuperATV frame stiffener to maintain structural integrity under extreme loads.

Whether you’re conquering mud pits, crawling rocky trails, hauling heavy loads, or building the ultimate workhorse, the SuperATV 4” GDP Portal Gear Lift delivers unmatched clearance, torque multiplication, and drivetrain protection for your Can-Am Defender HD11.
