SuperATV Can-Am Defender 8" Portal Gear Lift Kit

SuperATV Can-Am Defender 8" Portal Gear Lift Kit

Gear Down and Go Big

Your Defender isn’t YOUR Defender until you’ve got a big lift and some massive mud grips on it. SuperATV got the perfect thing for you—an 8” GDP Portal Gear Lift. That’s a huge lift, and you can choose from a 45% or 60% gear reduction to give you the boosted torque you need to turn your massive tires. 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?

GDP—the Most Trusted Name in Portals

Not sure if GDP is right for you? SuperATV  think it is, but why don’t you ask one of the thousands of riders already using portals every week? More riders roll on GDP portals than any other portal system. That means SuperATV got experience that no one else has. When it comes to reliability, quality, and performance, nothing’s as trail-proven as GDP.

45% and 60% Gear Reductions Destroy Mud

It seems like SuperATV see more Defenders in the mud every time they go out—it’s a great side-by-side for it. But with 8” portals and a 45 to 60% gear reduction, it becomes the ultimate mud UTV. You’ll have room for up to a 44” tire and all that torque means you can push through anything, if the mud’s even deep enough to reach your skid plate.

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.

Unmatched Gear Material

What’s more important than gears in a portal gear lift? Nothing. That’s why top-of-the-line gears are made from precision-ground 9310 alloy steel. They mate perfectly every time and give you smooth, quiet portals no matter how fast you go. GDP gives you luxury-grade performance.

Stronger Housings by Design

Some might think you can use brute force to make a better housing. They’d be wrong. SuperATV use 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 that will stand up to any ride.

• Housings are reinforced in all the right places
• They’re built with better oil flow and gearing forces in mind
• There are no gimmicks and no vents because vents do more harm than good

The Strongest Portal Backing Plates You Can Get

How do they make the strongest backing plates on the planet? SuperATV start with an advanced steel alloy that’s even stronger pound-for-pound than chromoly. Then, SuperATV make it 5/16 inches thick, and, finally, they hand-weld gussets and pivot blocks to it. SuperATV went all out on strength because if you’re backing plate doesn’t hold up, you’re done playing. So keep playing with GDP.

Advanced Gaskets and Seals

Whether you go with cast or billet, both housings use:

• Advanced Thermo-Tork® gaskets to keep oil in and water out. They have excellent oil resistance and a lower deterioration rate than Kevlar gaskets.
• A sealed input gear and double-lipped output seal.
• 100% sealing coverage throughout. You can forget about oil leaks—nothing’s getting in or out, ever.

Bearings That Rock

All the strongest housings, gears, plates, and hardware would mean nothing if they had just average bearings. But, like everything else, SuperATV opted to make them as good as possible. With a double-angular contact bearing on the output shaft that can take hit after hit, you can rest easy knowing that even GDP’s bearings are built for battle.

Universal Hubs and Slotted Rotors

Precision-ground, stainless steel slotted rotors stay cool to give you the braking power you need when you need it. They come with 4/156, 4/137, 4/115, and 4/110 bolt patterns and lugs so you can use wheels from just about any side-by-side. SuperATV invented the tapered output shaft that hubs attach to, which provides a more secure lock that won’t wobble or wear over time.

Frame Stiffener Required

These 8” portals are big beefy and powerful. In fact, they give you such a big lift that your Can-Am Defender needs a frame stiffener to keep from bending its chassis. SuperATV put it through its paces and bent plenty of frames. Trust us and get a frame stiffener.
