Comp Cams Crankshaft Sockets

When slipped on the end of a crankshaft, these specially designed 1/2" drive sockets allow you to rotate the engine assembly. These sockets also provide a great way to attach a degree wheel (Part number 249-4790 or 249-4791-1) to the engine. The unique design incorporates a knurled retaining nut that sandwiches the degree wheel and holds it in place.

Features:

• Specially designed 1/2" drive socket allows rotation of engine assembly
• Knurled retaining nut holds degree wheel in place
• Can be loosened while on crank snout so that wheel can be turned independent of the engine when finding TDC
