8" GDP Portals
Transform your four-wheeler into an absolute monster with SuperATV's 8" Portal Gear Lift. You'll be able to dominate mud, rocks, and other obstacles with strength and lift that seem almost impossible. And the muscular 60% gear reduction paired with your preference of a cast or billet housing will make you completely unstoppable.

An Incredible Upgrade with a 60% Gear Reduction
When you're diving into deep, thick mud, you can’t sacrifice power. Our 60% gear reduction restores the low-end power that big tires typically take away. That means your ride will have the power to plow through the deepest mud even when cranking huge, heavy tires.

Protects Your Drivetrain
With the gear reduction built into the wheel hub, our GDP portals take the load off the rest of your drivetrain. They take on the tough work, protecting parts like your axles, differential, driveshaft, and transmission from straining to move large tires.

GDP Portals are Unmatched
Our GDP 8" Portals are built to handle any abuse you put them through. You can choose between cast or billet aluminum. They're both ultra-strong and ready to take a beating. Plus, the strong steel alloy plates give them extra armor.

• 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
