Supercharger belt replacement is difficult to put on a time/mileage-based schedule due to the wide range of use these kits see. Kraftwerks Performance recommends regular inspection of the belt, the belts' tension, and the drive pulley's ware surface for the longest possible service life that is built into every belt we offer.
