See If This Product Fits Your Vehicle
Gear Down and Go Big Your Polaris General can get work done when it needs to, but if you want more ground clearance and the torque to run bigger tires in mud, SuperATV’s 8" GDP Portal Gear Lift takes it to another level. With 45% or 60% gear reduction, you can clear bigger rocks and power through thick mud with less strain on your machine.
GDP is a proven portal system trusted by riders with hundreds of thousands of ride hours on the trail and in the mud. The gear reduction is placed in the portal hub, which helps reduce stress on your axles, differential, prop shaft, and transmission so you can ride harder than stock with less wear.
Available with billet or cast aluminum housings, this kit features precision-ground 9310 alloy steel gears for quiet operation, a 1.5" forward and rear offset, and an increase in width of 4" per side (8" total). It also includes a 1.5" diameter 4340 hardened steel driveshaft, advanced gaskets and rubber O-rings, universal hubs, and slotted stainless steel rotors.
