Gear Down and Go Big
We know you like to go big, and it doesn’t get any bigger than an 8” GDP Portal Gear Lift. That’s a heck of a lot of room for up to 40” tires and a ton of torque thanks to the built-in gear reduction. Choose from 45%, 60%, and 70% reductions and boost your durability by upgrading to dual idler gears—you get portals built for you. Your Can-Am Maverick X3 will feel like a whole new machine when you’re towering over the competition and throwing up rooster tails better than anybody else.

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 Are Perfect for Mud
What’s the first thing you need if you’re serious about mud? A big lift. The second thing? Some big ass tires of course and the gear reduction to turn them. Our 8” portals have got you covered. You’ll have room to install huge 40” tires. And the 45, 60, and 70% gear reductions give you the most extreme torque to tear up the bounty hole. That way, you can push through and ride over deeper, thicker mud holes and take home the bounty.

A Gear Reduction That Protects Your Drivetrain
Portals put the gear reduction right in the hub. That puts it after your entire drivetrain and it makes your drivetrain work less and wear less. That means more miles out of your axles, differential, transmission, and prop shafts.

Stronger Housings and Backing Plates by Design
GDP Portals are the strongest you can get because we know how to make them tough. We’ve been using them and refining them for years. Whether you go with cast or USA-made, 6061 billet aluminum housings (which look awesome), you’ll get unmatched strength through superior design. Combine that with 5/16” backing plates made with an advanced steel alloy, and you’ve got the brawniest portals on the market.
  • 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 !!
    You need a SuperATV Frame Stiffener with your 8" Portal Gear Lift. The stock frame just doesn't have what it takes. Bump too hard and the OEM frame will bend. Trust us—we've done it. A frame stiffener reinforces your frame enough to let you ride your 8" portals with monster tires and no worries.
