GDP didn’t make the first side-by-side portal kit on the market—just the first kit that anybody gave a damn about. SuperATV’s GDP 6” Portal Gear Lift gives your Can-Am Maverick X3 a lift and a gear reduction, all in one box. Customize your ride by choosing a 30%, 45%, or 60% gear reduction, or boost your performance to the max with a dual idler gear portal. GDP is different from the rest. These portals were born from blood, sweat, and countless hours of real-world testing—all so you can enjoy your Can-Am X3 to the fullest.

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.

Perfect for All Riding Styles

You’ve never really ridden until you’ve done it with a GDP Portal Gear Lift. If you’re the kind of rider who’s always up for a challenge, these portals were made for you. From dunes to mud and everything in between, we’ve got a portal kit for every rider. Get a smaller 30% reduction for fast rides that pack plenty of torque. Go with a 45% gear reduction to run bigger tires and take on rougher terrain. Or build the mother of all mudders with a 60% gear reduction. You can even opt for dual idlers to really push your build over the edge. A portal gear lift gives you your torque back, so even the wildest and most massive build can run with the best of them.

Protect Your Most Vital Components

Portals place the gear reduction in the hub, meaning less stress is put on your drivetrain. Your machine’s most vital parts won’t have to work overtime to make up for the extra 6” of lift. Your axles, prop shaft, differential, and transmission will thank you, and they’ll last longer, too.

GDP is the strongest and most trusted portal gear system in existence. Our cast and billet aluminum housings are the thickest and strongest you can get, and they’re backed by unmatched real-world experience, so you can be confident that you’re getting a kick-ass product. Throw in our 5/16” backing plates made from an advanced steel alloy and you’re left with downright unstoppable Can-Am Maverick X3 portals.

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 Thermo-Tork® 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

Add Reinforcement with a Frame Stiffener

We highly recommend running a SuperATV Frame Stiffener with your 6" Portal Gear Lift. A frame stiffener reinforces your front end enough to let you ride your 6" portals with monster tires and no worries.
