PBI Steel Front Countershaft Drive Sprocket | 54-635-14
This is a premium, USA-made case-hardened steel front countershaft drive sprocket (PBI item code 54-635-14). CNC-machined from aircraft-grade 8620 nickel-chromoly steel alloy and finished with an electroless nickel plating, it acts as a direct replacement for hooked or worn front engine sprockets. It provides smooth chain alignment, controls dynamic chain slap, and eliminates slop on the output shaft splines to protect your crank seals from oil weeping. [1, 2, 3, 4, 5]
