This 420-pitch, 14-tooth countershaft drive sprocket is precision-machined from case-hardened chromoly steel alloy. It undergoes a advanced carbon-impregnated heat treatment to establish an ultra-hard outer surface shell, eliminating premature tooth deformation under severe acceleration. A heavy-duty parkerized surface coating is applied to finish the exterior layer, locking out moisture, track sand, and thick trail mud to prevent structural rust and aggressive corrosion over time.
