Precision engine work requires the right tools. PROFORM’s Professional Crankshaft Turning Socket allows engine builders to smoothly rotate the crankshaft during camshaft degreeing, engine assembly, and timing verification.
Designed for Big Block Chevy applications, this socket features a 1.610" inside diameter with a 3/16" keyway for proper engagement with the crankshaft snout. The socket slips over the crank and allows the engine to be rotated using a standard 1/2" drive breaker bar or ratchet, giving builders controlled movement during precise setup procedures.
An integrated mount allows an oversized degree wheel to be attached directly to the socket, providing a larger and easier-to-read reference when checking cam timing and valve events.
Constructed from non-marring aluminum, the PROFORM Professional Crankshaft Turning Socket is built for durability while helping prevent damage to the crankshaft during repeated shop use.
