Your cart is empty.This Crank Shaft Turning Socket by Proform is made from non-marring aluminum with an 1.255 inside diameter. Fits Chevy small blocks, I V6 and GM 4-cylinder engines. When your harmonic balancer is off, place this socket over the end of the crankshaft with a 3/16" keyway. Turning your crankshaft can be done with socket and a 1/2" breaker bar or drive ratchet.

This socket is so weak it couldn't turn 4 pistons set in a sbc. I can turn the crank by hand, but the drive rounded off, and is cracked. Would not recommend if you need it to turn more than 30 ft-lbs

A crank socket is the best invention since sliced bread. Works as expected.

I don't normally leave reviews but, I really like it. Great quality, and works as described. Prefect fit for my "Iron Duke" GM 4 cyl. crankshaft.

Makes it so easy to turn the engine over by hand when trying to find TDC...

Very light duty item, alum and the fit is rather loose.

Showed up with black finish. It does not have any stamping or labeling on it. Would be nice if it was stamped what it is like a socket. Overall does fit nicely on the crank and function well.

TL DR: Again, this tool should work great for rotating a fresh assembly, but don't expect it to free up stuck pistons.This socket fits very well onto the crankshaft snout. There is a little bit of wiggle room ... just the right amount. This product (and thus the reduction of a star) is a two part piece. The center portion where the ratchet or breaker bar would fit into (the 1/2" drive portion) is fit into the main socket portion, and is pinned into it with roll pins (one on each side). I think they do this to ease in manufacture, but it doesn't help me with what I needed. I was hoping this tool would help me free up a frozen engine, but I couldn't apply enough torque to it with the fear of shearing the roll pins. The outer wall of the socket is solid enough (it's about 5/16" to 1/4" thick), but the center section on mine now has a little play. Rather than destroying it, I left it alone so I could use it in the future for it's intended purpose, which is to rotate the crank when re-assembling an engine. It should work great for that, as you shouldn't have to apply much torque to it to rotate a fresh assembly.

For the price it's ok but it's pretty thin and feels a little cheap but for the price what do u expect

Very pleases with this tool thus far, I have been gentle with it and have no problems at all, works just as I needed. It isn't strong steel, but is a softer aluminum.

Worked perfectly! This tool is a life saver when it comes to properly lining up a timing chain assembly on a SBC engine! It turned my crankshaft with ease and saved me a bunch of time during my engine assembly! Thanks!Mike
