The popular Arctic 650/700 H-1 is calibrated fairly well for general use with stock tires, but oversized tires have a very negative effect. Many performance enthusiasts are well aware of the fact that even slightly bigger or heavier tires can substantially hurt acceleration and speed performance. The addition of this cost effective weight roller kit for the primary drive clutch helps recover some of that lost power. '06 and newer models MUST use the DA 650 HC kit with completed roller assemblies, as the plastic on the factory rollers are not removable.

This kit is intended to help with re-calibration for oversized tires. If installed on a unit with stock tires, it does show some gain in acceleration but slight loss of top speed. It also aids in restoration of power lost at higher altitudes.

*This kit is not for the Mud Pro 700 model. The Mud Pro version is calibrated fairly well for its application from the factory, and recalibrating the rate of shift of the clutch is not going to give significant gains.
