Primary CVT Shims - 0.2mm

This is the equivalent of the Coop45 shim mod for the Yamaha Rhino and Grizzly 350 400 450 500 550 600 660 700. This is (2) 0.2mm shim and will give you more low end torque by allowing your CVT belt to ride lower in the primary sheaves. This shim mod will also give you some of the low end torque back that you lost when larger rims and tires were installed. You may need multiple shims in order to recieve the desired low end torque for your application.
