Take Your Ride to the Next Level
You won't find anything like our third generation of portals anywhere else. Why? Because you get to be a part of the design process. With SuperATV's 8" Portal Gear Lift, you can choose your own gear reduction—45% or 60%—and your own housings—cast or billet aluminum. You won't be disappointed no matter which way you go.

GDP: The Most Trusted Name in Portals
More riders trust SuperATV for their portal needs than anyone else in the industry. That's because we know our stuff. We've invested more time and money in designing portal gear lifts than any other manufacturer. Thanks to industry-leading technology and countless hours of field and lab testing, we're able to deliver exactly what you need to take your ride to the next level.

We Know All About Mud
Everyone knows you can't truly enjoy mud pits if you're not rolling on GDP. The extra lift will keep you from getting swamped in deep bogs and also give you room for bigger tires. And don't even get us started on the torque boost! Our gear reduction—either 45% or 60%—will have you cutting through the mud like it's nothing.

A Gear Reduction That Protects Your Drivetrain
With the gear reduction all the way at the hub, you get reduced stress on your axles, differential, prop shaft, and transmission. That means your components will last longer than stock even though you're riding harder.

The Strongest Portal Housings and Backing Plates You Can Get
We use an advanced steel alloy for our backing plates. They're stronger than chromoly and at 5/16 inches thick, they'll stand up to anything and everything the trail throws at you. We've also spent years tweaking and honing our portal housings to make them as strong as possible. With tens of thousands of housings in the wild proving their strength every weekend, you know you're getting the best. So go with cast or super-sleek, USA-made billet aluminum—either way, you're getting the best.

• 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
