EFI 24x Crank Reluctor for GM 7.4L L21 Engine 12552480

For use with L21 7.4L Vortec big-block Chevy engines in C6500 and C7500 vehicles. This reluctor produces the 24x crank signal required by the Gen III LS type PCMs.

This is a high quality reproduction of GM's discontinued 12552480 crankshaft reluctor. Our reluctor is manufactured from one piece billet steel (where GM's reluctor was two-piece die cast).
