Accessory Drive and Crank Mandrel Fasteners

Accessory Drive and Crank Mandrel Fasteners prevents mandrel bolt breakage and is made specifically for use with crank pulley. Mandrel is attached to the crankshaft pulley with three bolts, while the vibration damper is retained with the stock bolt. The mandrel bolt is then connected to the mandrel, not to the crankshaft, to reduce engine harmonics (helps prevent loosening or breaking).
