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

Sturdy pinion for TRF 04 applications

The Tamiya 42224 - RC TRF 04 Module Pinion Gear (25T) is a practical upgrade for racers wanting steadier drivetrain behaviour. Manufactured from hard-coated aluminum, it is built to resist track wear while maintaining efficient power transfer to the spur gear.

Hard-coated aluminum for durable use

Made from quality aluminum with a hard finish, the Tamiya 42224 pinion improves wear resistance without adding excessive weight. Its rounded tooth profile reduces friction during meshing, helping to deliver smoother torque and steadier motion under load.

Vehicle fitment and racing use

This pinion is suited to TRF416, TRF417 and F1 cars that use 04 module spur gears. The 25-tooth sizing provides a sensible compromise between top speed and acceleration, making it useful across a variety of track types and race setups.
