This kit features a set of spacers of varying thickness that are used to change and adjust the tension of the CVT drive belt in a Polaris RZR XP-Turbo. Also eliminated, is the need to use the factory circlip and recessed washer.A properly adjusted drive belt will help maintain desired gear ratios, will eliminate vehicle creeping at idle and will allow for smoother shifting and drive gear engagement. It can extend the life expectancy of the drive belt and can help compensate for belt wear and manufacturing variances in the belt and other clutch components.
