Turn Your Ride into a True Monster
If you ask any rock crawler or mud enthusiast how they dominate the terrain, chances are their answer will be GDP Portals. Turn your ride into a true powerhouse with a SuperATV 4" Portal Gear Lift. Experience unmatched performance with a kit that combines a lift and gear reduction in a single package. Select either a 15% or 30% gear reduction to maximize torque, and choose between durable cast or billet housings for superior strength.

Built for All Terrain
GDP Portals are designed to match your riding style and terrain. A 15% gear reduction delivers extra torque while maintaining the speed you need for fast trails and dunes. Go for the 30% gear reduction to handle big tires, deep mud, and serious rock crawling with ease. If you like pushing your ride to the max, portals are the ultimate upgrade.

Protect Your Drivetrain
Since the gear reduction happens right in the wheel hub, our GDP portals take the pressure off the rest of your drivetrain. They do the hard work so parts like your axles, differential, prop shaft, and transmission don't have to struggle to move those big tires.

You Can't Beat GDP
We built these portals to take a beating. With cast or billet aluminum housings, they're tough enough for whatever you throw at them. Plus, we back them up with strong steel alloy plates, so you're getting strength and quality you can really rely on.

• 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

Get Extra Reinforcement with a Frame Stiffener
Rough riding and added weight can wreak havoc on your machine's frame if it's not properly reinforced. That's why we strongly recommend adding a SuperATV Frame Stiffener when installing your new portals. It adds all the support you need to tackle hard rides in confidence.
