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

Reliable pinion for TRF 04 gear trains

The Tamiya 42224 - RC TRF 04 Module Pinion Gear (25T) makes a solid improvement for model drivers aiming for consistent drivetrain performance. Crafted from hard-coated aluminium, the gear resists wear from frequent track sessions while retaining efficient power transfer.

Durability from a hard-coated aluminium build

Using high-grade aluminium with a protective hard coat, the Tamiya 42224 pinion increases service life compared with untreated gears. The smoothed tooth profile lowers friction at each mesh point, helping to maintain steady torque flow and reduce heat build up.

Where this pinion fits best

Designed for TRF416, TRF417 and F1 cars that use 04 module spur gears, the 25-tooth layout balances speed and torque. It is well suited to tight circuits and mixed-surface club racing where a reliable gearing choice is important.
