Replacement IHI drive pin bushing. Sold as a single item. There are 8 total in a supercharger.
Note: It has come to our attention that installers are using the drive snout to draw the couplers into the pockets. If you use this method, you may cause damage to the supercharger that may cause it to need service. They should be pressed into the hub before drive installation.
Note: These can be used on Verado superchargers, but must be ground down to 8mm. As soon as we can get some produced exactly, we will list them.
