GDP Portals Are the Xpedition’s Best Friend
More ground clearance, more torque, and bigger tires—they’re the perfect ingredients for better overlanding adventures. That’s why you need SuperATV’s 4” GDP Portal Gear Lift on your Polaris Xpedition. It gives you a 4” lift, your choice of a 15% or 30% gear reduction to boost torque, and room for 33” tires. And you can maximize your strength by choosing billet aluminum housings and dual idler gears. It’s the portal gear lift built for the best.

• Gives you a 4” lift and a gear reduction in one package
• Choose a 15% or 30% gear reduction
• Maintains OEM suspension angles
• Choose dual idler gears for ultimate strength

What Is a Dual Idler?
We’ve put years of research and development into making our dual idlers the best in the industry. With two idlers in the portal box, the load gets spread over two gears instead of one. But it doesn’t work unless the two idler gears are mated perfectly. Precision CNC grinding ensures ours are. Our gears are made from the industry’s toughest 9310 steel alloy. If you don’t think dual idlers matter, think again. With GDP’s quality and experience, they take strength to the next level.

Ride How You Want with 15% and 30% Gear Reductions
GDP portals let you ride anywhere and everywhere with boosted performance and capability. That’s because the built-in gear reduction gives you more torque and acceleration. If you run with big tires or heavy cargo that weighs you down, portals give you power back. Choose a 15% gear reduction to maintain a high top speed with plenty of power. Or go over the top with 30% to make sure bigger tires and heavy loads won’t bog you down.

Portals Protect Your Drivetrain
GDP Portals put the gear reduction in the hub at the end of your drivetrain. That means that all your Polaris Xpedition’s drivetrain components benefit from it. Your axles, differential, prop shafts, and transmission all work less and will last longer.

The Strongest Portals You Can Get for Your Xpedition
When you’re a hundred miles away from nowhere, you need everything on your overlander to be as reliable as possible. Our cast and 6061 billet aluminum housings are built for any challenge. They come paired with our advanced steel backing plates that provide the best strength in the industry. If you want to make it through any adventure, you want GDP.

• 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
