- This kit was designed, tested and developed on a two seat version of this vehicle. CVT clutch calibration is “controlling rate of shift of the belt” in many situations. It is related to HP, weight of the vehicle, terrain application, tires, etc. The correct clutch calibration is always vehicle and application specific. In some instances of other side by side vehicles we can use the same or similar kits in both vehicle versions with different instructions. In others, it requires a kit with some different components. Although these parts will physically “fit” the clutches, we have not tested a four seat version of this vehicle and thus it may be irrelevant and we cannot comment or make recommendations for that application.
