Lightweight Pinion Upgrade for Better Drive Feel

The Tamiya 42266 TRF 04 hard coat aluminum pinion gear is built to improve drivetrain response in RC models that use 04 Module gears. Made from light aluminum with a hard coat finish, this pinion reduces friction and resists wear to keep power delivery smooth and predictable under load.

Benefits of a Hard-Coated Aluminum Pinion

Aluminum pinions are popular among racers for cutting rotating mass and aiding acceleration. The TRF 04 design pairs lightweight construction with a protective hard coat to extend service life while maintaining consistent meshing and drivetrain efficiency.

Fitment Notes and Installation

This pinion fits any Tamiya vehicle that uses 04 Module gears and comes with a 3mm grub screw for a secure fit. Check gear mesh during installation and tighten the grub screw to prevent slippage.

Which Tamiya models will accept this 04 Module pinion?

Any Tamiya model specified for 04 Module gears can use this pinion. Confirm the motor pinion module matches your gearbox and check space for the 36T tooth count if clearance is tight.

How does the hard coat improve performance?

The hard coat reduces surface wear and lowers friction between gear teeth, which helps keep power transfer smooth and reduces heat buildup over repeated runs.

Any tips for installing the pinion?

Fit the pinion so the gear mesh is correct, tighten the included 3mm grub screw, and recheck after a short test run to ensure nothing has shifted.
