Race-Grade 3Racing 64 Pitch Spur Gear 78T

Specifically for tuning and competitive rigs, the 3Racing 64 Pitch Spur Gear 78T provides a predictable tooth profile that aids in fine adjustments to gear mesh and acceleration response. The 78-tooth choice supports lower effective gearing without sacrificing smooth engagement.

Technical race notes

The spur is produced to tight dimensional tolerances to limit backlash and uneven wear. When paired with properly matched 64 pitch pinions and correctly set mesh, it helps maintain consistent lap-to-lap performance and simplifies setup changes during events.

How does this spur affect gear ratios for racing?

A 78T spur moves the overall ratio toward more torque at the wheel, which can aid corner exits and traction on tight tracks. Use pinion size adjustments to dial in top speed.

Recommended inspection routine for race events?

Inspect tooth faces for wear between qualifying runs, verify mesh after any hard impacts, and rotate spurs into service only when smooth engagement is confirmed.

Pinion selection advice for different tracks?

For tight, technical tracks choose a smaller pinion to improve acceleration; for faster layouts increase pinion teeth while monitoring motor and ESC load.
