EFI Connection's 58x crankshaft reluctor was designed to generate the 58 pulse crank signal required by the GM Gen IV LS-Series ECMs. This reluctor is 5.315 inches in diameter and must be used with an EFI Connection two-piece billet aluminum timing cover. Its profile was designed for both single and double roller timing chain clearance.

IMPORTANT! Cannot be used with timing covers that receive 4.000 inch crankshaft reluctors.
