Protect Your Drivetrain with GDP Portals GDP Portals move the gear reduction to the wheel hub instead of the transmission. This setup helps keep your axles, prop shaft, differential, and transmission safer by putting less stress on them. You get more power without wearing out your drivetrain.

Combine that with our backing plates that are made of advanced steel alloy and you’re getting the toughest 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 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 rig is built to take on extreme terrain and wild obstacles, but that doesn’t mean its frame can handle the heavy-duty awesomeness of 8” GDP Portals.
