Race grade gear mesh for precise drivetrain tuning

Engineered for racers who demand repeatable engagement, the 3Racing 64 Pitch Spur Gear 125T provides a predictable tooth profile that supports consistent lap-to-lap performance. It is useful when refining gear ratios for specific circuit sections.

Performance focused characteristics

The 125 tooth 64 pitch form reduces incremental backlash and distributes load across more teeth during drive cycles, helping to stabilise torque transfer and improve throttle modulation through corners.

Application and setup notes

Ideal for 1/10 scale competitive cars using 64 pitch components, this spur works well when paired with hardened pinions and correct mesh settings; racers should fine tune pinion size and shimming for optimal temperature and wear behaviour.

What pinion materials pair best with this 125T spur?

Hardened steel pinions are preferred for high torque or brushless rigs to minimise wear; brass or aluminium pinions can be used for lower stress applications but will wear faster.

How should I set mesh for optimal durability and low friction?

Aim for a light contact pattern using a marker method, avoid excessive tightness, and check for even wear after short runs. Proper cooling and lubrication also extend service life.

Any race day checks recommended after installing this spur?

Confirm secure mounting, verify mesh under static rotation, inspect for foreign debris, and run a brief warmup to validate temperatures before full competition pace.
