When installing a high performance alternator the fit of the pivot bolt plays a critical role in proper alignment. Far too often we find a 3/8" bolt being used in an alternator with a 10mm ID mounting foot. The CMI RS2 solves this problem. Simply slide it into the alternators 10mm ID foot and you can now use the 3/8" bolt your engine bracket is using.

The CMI RS2 can even be doubled-up, if needed, or used on even slightly larger bolt diameters to create the a better pivot bolt fit.

IMPORTANT: This item is easily damaged due to the thin nature of the material. We suggest you consider ordering two at a time.
