The SuperATV 8" GDP Portal Gear Lift for the 2014-2023 Polaris RZR XP 1000 or RZR XP 4 1000 lifts the machine 8 inches at the hubs and adds a 45%, 60% or 70% gear reduction. Choose cast aluminum or billet aluminum housings and single or dual idler gearing 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.
Pair it with the Polaris RZR XP 1000 Frame Stiffener, sold separately.
