Tamiya 53966 - 48P Pinion Gear Set for TRF501X/DB01 - Race Ready 20T/21T Pinions  [53966]

Adjust Gearing for Speed or Torque

Swap between 20T and 21T pinions from this Tamiya 48P set to alter your car's power delivery. Built from aluminium with a titanium-colour finish, these pinions are a practical choice for racers running TRF501X or DB01 chassis who tweak ratios trackside.

Compatibility and Performance Notes

The Tamiya 53966 pinions give consistent tooth form for reliable mesh and repeatable behaviour. Use them to bias your setup toward quicker acceleration or higher top speed, but do not use them with the 540SH or RS-540 Sport Tuned Motor.

Modular Tuning with Tamiya Parts

These pinions are compatible with Tamiya parts 53964 and 53965 for stepped tuning options. They are useful when you want small, controlled changes rather than swapping large components.
