Kraftwerks Performance Replacement Belt for the First Gen. 20mm Wide Cog Belt found in the '13+ BRZ/ FRS/ FT86 Supercharger Kit.

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. Remember, when in doubt... replace!!
