Make Your Ride a Mud Machine
Dominate the bog with SuperATV's 8" Portal Gear Lift. Room for 33" tires and impressive torque from our gear reduction will make your ride the most wanted rig in the swamp. Choose a 45% or 60% gear reduction for incredible power that won't back down. Transform your ride with GDP Portals from SuperATV!

45% or 60% Gear Reduction for Mud Mastery
When it's time to tear up the bounty hole, you need a gear reduction. Gear reduction reclaims the lost torque required to turn bigger tires, giving you the strength you need to make short work of deep mud. Choose a 45 or 60% gear reduction to upgrade your ride into a mud-slinging monster.

Gear Reduction That Protects Your Drivetrain
Our portals protect your drivetrain. How? By putting the gear reduction directly in the hub. Hub-based gear reductions make sure your drivetrain doesn't get overworked, giving you more miles from your differential, transmission, prop shaft, and axles.

Stronger Housings and Backing Plates by Design
GDP Portals are the strongest you can get because we know how to make them tough. We've been using them and refining them for years. Whether you go with cast or USA-made, 6061 billet aluminum housings (which look awesome), you'll get unmatched strength through superior design. Combine that with 5/16" backing plates made with an advanced steel alloy, and you've got the brawniest portals on the market.

• 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
• Roller idler and drive bearings to maintain perfect gear meshing

Reinforce Your UTV with a Frame Stiffener
Your ride is tough, but that doesn't mean its frame can handle the extreme performance of 8" GDP Portals. That's why a frame stiffener is required. We've ridden hard enough to know that frame damage happens. So get a frame stiffener and don't worry about it.
