Tamiya 42224 TRF 04 25T Hard-Coated Aluminium Pinion Gear  [42224]

Performance-minded 25T pinion for TRF 04

The Tamiya 42224 - RC TRF 04 Module Pinion Gear (25T) is a straightforward upgrade for tuners looking to sharpen drivetrain response. The hard-coated aluminium construction helps the pinion stand up to repeated race use while keeping power transfer efficient.

Hard-coated aluminium for consistent wear resistance

Finished in a protective hard coat, the Tamiya 42224 pinion improves durability compared with plain aluminium gears. The rounded tooth form lowers friction during engagement, which helps preserve gear faces and smooth out power delivery during hard acceleration.

Compatibility and practical use cases

Suitable for TRF416, TRF417 and F1 chassis that accept 04 module spur gears, the 25-tooth option offers a sensible trade-off between top speed and launch response. It is a good selection for club racing and setup testing.
