Description
A worn or damaged countershaft sprocket compromises power delivery and creates inconsistent acceleration across the entire RPM range. This 13-tooth JT sprocket restores precise gear engagement and maintains the exacting tolerances your engine demands, whether you’re pushing hard on the track or dialing in your setup. Built from SCM420 chromoly steel, it’s engineered to handle repeated shock loads and maintain dimensional stability through hundreds of heat cycles.
