For competitive tuning, precise tooth count and pitch matter. The 3RACING 64 Pitch Spur Gear 87T 3RAC-SG6487 provides the finer increments required when optimising final drive for different circuits and motor types, aiding consistent lap timing and predictable throttle control.
Using an 87T spur at 64 pitch reduces step size between gear ratios, letting crews make small, controlled changes to top speed and acceleration. This helps when adjusting setups to track grip, battery output, and motor torque curves.
The spur fits common 1/10 drivetrains and is intended to be used with matching 64 pitch pinions. For best results, set mesh precisely, verify runout, and test under competitive conditions to confirm consistency before finalising setup.
