EFI Connection's 4x crankshaft reluctor was designed to generate the 4 pulse crank signal found in 1996-newer SBC and LT1 engines. This reluctor is 4 inches in diameter and must be used with an EFI Connection billet aluminum timing cover. Its profile was designed for both single and double roller timing chain clearance.

IMPORTANT! Cannot be used with production GM 1996-newer SBC and LT1 timing covers due to crank seal backstop interference.

IMPORTANT! For use with SBC and LT1 engines with BBC crankshaft snout.
