The SuperATV 4" GDP Portal Gear Lift for the 2015-2018 Yamaha Wolverine lifts the machine 4 inches at the hubs and adds a 15% or 30% 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.
