SuperATV HD5 8in. Portal Gear Lift for Can-Am Defender

Your Defender HD5 isn't YOUR Defender until you've got a big lift and some massive mud grips on it. That's a huge lift, and you can choose from a 45% or 60% gear reduction to give you the boosted torque. If you want the most extreme ride, opt for SuperATV 70% gear reduction paired with dual idler gears. With a little help from GDP, you can have the biggest portal lift and gear reduction at the bounty hole. What's gonna stop you now?

What Is a Dual Idler®?

Perfection takes time. 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. Didn't think dual idlers mattered? With GDPs quality and experience, they finally do.

45%, 60%, and 70% Gear Reductions Destroy Mud

With 8 portals and a 45%, 60%, or 70% gear reduction, it becomes the ultimate mud UTV.

A Gear Reduction That Protects Your Drivetrain

Portals put the gear reduction right in the hub. That matters because putting it after your drivetrain components will make them last longer. GDP reduces the stress on your axles, differential, prop shaft, and transmission even if you're rolling on huge tires.

Stronger Housings and Backing Plates

SuperATV uses precise design honed over years and backed by hundreds of thousands of ride hours to make the strongest portal boxes in the industry. So whether you want cast or USA-made billet aluminum for your housings, you know your getting high-quality, precision hardware.

• SuperATV housings are reinforced for gear retention and optimized for oil flow
• Advanced steel alloy backing plates are stronger than chromoly

Advanced Gaskets, Seals, and Bearings

SuperATV 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

Frame Stiffener Required

These Can-Am Defender 8 portals are big, beefy, and powerful. In fact, they give you such a big lift that your UTV needs a frame stiffener to keep from bending its chassis.
