Supercharger belt replacement schedules vary based on usage, driving conditions, and power levels. Kraftwerks recommends regular inspection of belt condition, proper tension, and drive pulley wear surfaces to maximize service life. Environmental factors such as dirt, debris, temperature extremes, and pulley alignment all affect belt longevity. When in doubt about belt condition, replacement is recommended to prevent performance loss or potential failure.

Note: Kraftwerks offers an upgraded 30mm cog belt and pulley system that is 57% stronger than the original 20mm belt design for customers seeking increased durability and performance capacity.
