8” portal gear lift built for the Polaris RZR RS1. It adds lift at the wheel hubs and puts the gear reduction in the hub, so you get ground clearance and extra torque without asking more of the drivetrain behind it. Choose cast or billet aluminum housings to set the kit up for the riding you do.
Choosing your setup: Cast housings keep the price down, while billet housings are machined from solid aluminum for maximum strength. The frame stiffener option adds SuperATV’s frame stiffener kit (+$150.95) — worth adding on machines that will see hard use with big tires.
Gear reduction on this 8” kit is fixed by the kit — there is no reduction option to pick. You choose the housing material and whether to add the frame stiffener.
