Supercharger Shims (pack of 2)

These shims will fit any year or model supercharger. They are placed between the spring washers to put more tension on the clutch assembly to increase tension on the clutch assembly after it has worn.

This pack comes with two shims, but only install one and test the slip moment. If it is still too low then install the second shim and test the slip moment again. Never install more than two shims. If you have two shims installed and the slip moment is too low it's time for new metal washers and gear or you may opt to go with a complete rebuild kit along with a fresh set of metal washers.
