Description

Size A drill bit.

The original bushings were an extrusion with tolerance issues. Sold as a single item. There are 8 total in a supercharger. We recommend replacing the drive pins if your pins have wear. It the bushing pulls out of the pocket or off the pin easily, it is worn. Please note that our bushings are a self clearance, light press fit to eliminate the wear from a sloppy fitting bushing. After installation, use  Size A drill bit to size properly for pins. These bushings will last the life of the supercharger (80,000 miles), even under extreme use when properly installed. NOTE: Worn or rusty drive pins should be replaced by our high strength stainless drive pins. If your pins have no wear or damage, they are acceptable to leave in place.
