This is a factory-replacement 14-tooth steel front countershaft drive sprocket manufactured by Sunline (part number 1441-520-14). Cut from case-hardened SCM420 chromoly steel alloy, it directly replaces worn, hooked, or thinned front engine sprockets. It features integrated self-cleaning mud clearance grooves machined into the base of the teeth to prevent dirt packing, clear chain binding, and maintain uniform drive chain tension on muddy tracks.
