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
