RBS is here to help with this Moroso crankshaft socket that allows the racer to slip the socket over the nose of the crankshaft with a piece of .187" keyway installed and turn the engine over using a 1/2" drive tool. If using with a 1/4" keyed crank buyer will have to make a step key to use the tool.
Socket is made from billet heat-treated steel, zinc plated for corrosion protection and will fit the nose of a 1.600" big block Chevy.
