The SuperATV 8" GDP Portal Gear Lift for the 2020+ Polaris General XP 1000 or General 4 XP 1000 lifts the machine 8 inches at the hubs and adds a 45% gear reduction. Choose cast aluminum or billet aluminum housings to match how you ride. The gear reduction in each hub relieves stress on your drivetrain, so you can run bigger tires without overworking axles and the transmission.
