Product Description:
CGM Crank/Balancer Bolt For LS Engines - 12557840
Will fit all LS engines except LS7, LS9 and LSA engines.
When replacing the crank/balancer on an LS1 motor the bolt has to be changed every time because it is a torque to yeild bolt (meaning it stretches and can't be used again).
*NOTE: The ARP crank bolt we sell is NOT a torque to yeild bolt and can be reused.
