SuperATV GDP 4" Cast Aluminum 15% Gear Reduction Portal Gear Lift For Big Lift Kit

Ride when, where, and how you want with SuperATV’s GDP 4" Portal Gear Lift. Get a 15% gear reduction for faster rides with enough torque to start getting wild. Portals put the gear reduction in the hub, which greatly reduces the amount of stress put on your vehicle’s most crucial components. Knowing that your axles, differential, prop shaft, and transmission are in good hands lets you ride harder without worry. These cast aluminum housings are the thickest and strongest you can get. Combine that with 5/16” backing plates made from an advanced steel alloy, and our portals are unstoppable.
