SuperATV 8" Single Cast Portal Gear Lift Kit w/ 45% Gear Reduction & Frame Stiffener Can-Am Defender w/ Big Lift Kit 2016-2021 PGH8-7-90-453-FS | Vivid Racing

Your Defender isn't YOUR Defender until you've got a big lift and some massive mud grips on it. We've 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. If you want the most extreme ride, opt for our 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?

Perfection takes time. After years of research and development, we've made our dual idler gear portals unlike any other. 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. Precision CNC grinding ensures ours do. Our gears are made from the industry's toughest 9310 steel alloy. Didn't think dual idlers mattered? With GDP's quality and experience, they finally do.

It seems like we see more Defenders in the mud every time we go out-it's a great side-by-side for it. But with 8" portals and a 45%, 60%, or 70% 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.

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.

We 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. And when you reinforce them with 5/16" backing plates made with and advanced steel alloy, you have portals that will outlast any other.

  • Our housings are reinforced for gear retention and optimized for oil flow
  • Advanced steel alloy backing plates are stronger than chromoly
  • Enhance with Portal Blood-gear oil formulated for GDP Portals
  • There are no gimmicks and no vents because vents do more harm than good-we know because we tested them
Advanced Gaskets, Seals, and Bearings

Our 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
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. We've put it through its paces and bent plenty of frames. Trust us and get a frame stiffener.

Who is SuperATV?

Over the last few decades, ATVs and UTVs have gained their fair share of the limelight in the automotive industry. Gone are days when these vehicles are just meant for work or to transport someone from point A to B. Today, people are trying to modify these vehicles for recreational purposes. 

There was not that much aftermarket support for these types of vehicles back in the day. Either you settle with some of the factory-produced upgrades or create your own. Thankfully, the aftermarket industry started offering performance upgrades, and SuperATV is one of them.

SuperATV is a company that specializes in producing parts and accessories for ATVs and UTVs.

Today, they offer a more comprehensive range of products and cater to almost all brands such as Polaris, CanAm, Honda, Yamaha, Kawasaki, Arctic Cat, Suzuki, Bobcat, and more.
