Redefine Your Ride with GDP Portals
People use the machine for mud, dunes, racing, trail riding, and everything else. Now you can take your ride to the next level with a 4" GDP Portal Gear Lift from SuperATV. It gives you a lift kit and a gear reduction in one package for unbeatable performance gains. Choose a 15% or 30% gear reduction to boost your torque and cast or billet housings for extreme strength. GDP gives you the option to build your ride your way.

Perfect for Any Terrain
We don't believe in one-size-fits-all riding. That's why GDP Portals are made for the terrain and ride style you want. A 15% gear reduction gives you more torque while keeping the speed you need for fast trails and dunes. The 30% reduction gears you down for big tires, deep mud, and serious rock crawling. If you like pushing your ride to its limits, portals are the best way to do it.

The Strongest Portals on Earth
GDP Portals are built to outlast anything else. Choose cast or billet aluminum housings—they're both thicker and stronger than the competition. Add our 5/16" advanced steel alloy backing plates, and you've got the most durable portal gear lift for your ride.

• 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
