8” BILLET 70% DUAL IDLERS WITH ROTORS AND BRACKETS COMPLETE SET

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. 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?

What is a Dual Idler®? 

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. 

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

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.
 

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
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

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