This is a factory-replacement 13-tooth steel front countershaft drive sprocket (Sunstar part number 33713). Manufactured from case-hardened chromoly steel and finished with a rust-resistant black parkerizing surface treatment, it directly replaces hooked, thinned, or worn engine output sprockets. Replacing a worn front sprocket keeps your chain tracking straight, limits high-speed drive vibration, and prevents damage to your engine's countershaft seals. [1, 2, 3]
