COMP Cams 4797CPG Crankshaft Socket 1/2 in. Drive with Knurled Retaining Nut

The COMP Cams 4797CPG is a crankshaft turning socket, also called a crank socket. COMP Cams lists it as the Big Block Chevy Crank Socket.

Key Features:

• Knurled retaining nut holds a degree wheel in place
• The nut can be loosened while the socket is on the crank snout. This lets you turn the wheel independently of the engine when finding TDC.

This socket is useful for camshaft degreeing and other engine assembly work where you need to turn the crankshaft by hand.
