This 76-tooth spur, cut to 64-pitch standards, is built for use in RC drivetrains as a spare or swap-in for 64-pitch gear trains. It provides a simple way to alter final drive behavior while keeping motor and ESC settings the same.
Installation guidance: match the spur to a 64-pitch pinion, check gear mesh and backlash carefully, and ensure the spur turns freely on the shaft without rubbing on bearings or housing features. Gradual tightening and a load check will help protect the gear teeth.
Tuning impact: choosing a 76-tooth spur increases torque at the wheels and lowers top speed, which can improve throttle modulation and traction in technical driving. Use the pinion tooth count to compute the new gear ratio for expected handling changes.
