No. 22 Eddy, engine rotation socket. 10-spline

When you are building an engine or adjusting pushrods, you need a reliable way to turn the crank. This Fast Eddy engine rotation socket is designed for 10-spline sprocket shafts found on 1955 to 2006 Big Twins, excluding 2006 Dyna models. It is machined from heat-treated 4140 steel with a durable Cerakote finish. We have designed the spline fit with a tiny amount of extra play, ensuring the socket slides onto the shaft easily even if there are minor burrs or defects from years of use. Whether you are checking timing or valve clearance, this tool makes rotating the assembly smooth and controlled. Sold individually, it is a workshop staple for any Big Twin specialist.
