Engine assembly and camshaft degreeing often require repeated crankshaft rotation, and using the right tool makes the job easier and safer. PROFORM’s Crankshaft Turning Socket provides a simple and effective way to rotate the engine when the harmonic balancer has been removed.
This lightweight non-marring aluminum tool features a 1.610" inside diameter with a 3/16" keyway and slips over the end of the crankshaft for proper engagement. Once installed, the crankshaft can be easily rotated using a standard 1/2" drive breaker bar or ratchet, giving engine builders the control needed during assembly, timing checks, and camshaft degreeing.
Designed for durability and repeated shop use, this purpose-built tool helps prevent damage that can occur when using improvised methods to rotate the crankshaft.
Fits 1965–1992 Chevrolet applications. The PROFORM Crankshaft Turning Socket is a must-have tool for builders who demand precision during engine setup.
- 1.610" ID with 3/16" keyway.
