Proform Engine Crankshaft SocketFits SB Chevy 66901

Description:

1.225in ID with 3/16in keyway. Engine work requires repeated crankshaft rotation. This non-marring, aluminum tool rotates the crankshaft the proper way, when the balancer is off. Making sure to have the proper size, position this socket over the end of the crankshaft, so it can be turned using a 1/2in breaker bar or drive ratchet.
