This is a factory-replacement 14-tooth steel front countershaft drive sprocket manufactured by Moose Racing (part number M602-66-14, supplier code M855-14). Fully machined from high-strength SCM420 chromoly steel alloy and case-hardened, it replaces hooked or worn engine sprockets. Changing a worn front sprocket stops chain tracking slop, reduces driveline vibration, and protects your output shaft seals from tearing. [1]

- Made from case-hardened SCM420 chromoly steel to stop teeth flexing or hooking under high engine load.
