Take Your Ridge to the Next Level with GDP Portals
Turn your ride into a true powerhouse machine with SuperATV's 4" GDP Portal Gear Lift. You get a lift and gear reduction—all in one package. We offer them in a 15% and 30% gear reduction with a choice between cast or billet housing. They don't just give you the power to conquer tough terrain—they also give you the ability to run up to 31" tires.

Tackle Any Terrain
A gear reduction makes a big difference when it comes to tackling certain terrains. For faster speeds and solid torque, choose a 15% gear reduction. If you're running larger tires and hitting rough trails, a 30% gear reduction would be your best bet.

Protect Your Ride's Drivetrain
GDP Portals protect your drivetrain by putting the gear reduction in the wheel hub instead of the transmission. It keeps your axles, prop shaft, differential, and transmission safe by putting less strain on them. You're getting ultimate power without the worry of causing any damage.

Ultimate Strength
We made sure that our GDP Portal Gear Lift would be as strong as your ride. They come in a cast or billet aluminum housing. Throw in our backing plates that are made of advanced steel alloy and you're getting the ultimate 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 and O-rings with excellent oil resistance and low deterioration rates
• A sealed input gear and double-lipped output seal
