A Big Lift with Big Power
Your ride isn't supposed to be an average UTV. Install an 8" GDP Portal Gear Lift and it will be anything but. It gives you awesome ground clearance, boosts power with a 45%, 60%, or 70% gear reduction, and makes you a beast everywhere you roll. You'll dominate monster mud holes and crazy rock gardens like they're not even there.

What Is a Dual Idler?
After extensive testing and refinement, we've perfected our dual idler gear portals. These portals feature two idler gears that are precision CNC-ground, ensuring a flawless fit for enhanced torque transfer and superior performance. Constructed from durable 9210 steel alloy, these idler gears are built to last. With GDP's reputation for quality and expertise, you can trust that these are robust portals capable of conquering any obstacle in the path of your ride.

Use a 45%, 60%, or 70% Gear Reduction to Master the Mud
If you want to dominate deep mud holes that swallow other riders whole, there's only one way to do it. With 8 inches of extra ground clearance, you won't get in over your head. But what really makes it tick is the 45%, 60%, or 70% gear reduction built into the hubs. You get tons of torque to turn big tires through the deepest, nastiest mud you can find. A set of portals will turn you into the master of mud.

A Gear Reduction Protects Your Drivetrain
When the gear reduction is in the hub instead of the transmission, your entire drivetrain benefits from it. Your axles, differential, prop shafts, and transmission will face less wear and tear thanks to this gear reduction.

Stronger Housings by Design
Whether you choose cast or billet aluminum for your housing, you know you're getting a housing that's built for battle. We've spent years refining our housing design to maximize strength in key areas that see the most force. With more than ten thousand housings out on the trail, you know they're built to last. Combine them 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 and Seals
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

Reinforce Your UTV with a Frame Stiffer
These 8" portals are hardcore. In fact, they're more hardcore than your ride. You need a heavy-duty frame stiffener to make sure that your UTV survives all the action packed rides you're about to go on. Trust us, we've bent more frames than we can count. Don't mess around. Get a frame stiffener.
