JEGS Crankshaft Reluctor Wheel

Pressed onto your crankshaft, JEGS Crankshaft Reluctor Wheel gives the crankshaft position sensor a true reading of where the crankshaft is in relation to the engine. This allows your LS engine to operate at optimum efficiency and power. The 24-tooth wheel is designed to fit pre-2006 Chevy LS Series engines. You will want one of these if you are swapping or building your own LS shortblock engine. Steel construction.
