Tamiya 42269 TRF 04 Hard Coat 39T pinion for improved drivetrain smoothness

The Tamiya 42269 TRF 04 Hard Coat Aluminum Pinion Gear 39T combines a light aluminium body with a tough hard coat to minimise surface wear. This balance helps maintain efficient power transfer and consistent gear life in regular use.

Durability and design highlights

Made from quality aluminium and treated with a hard coating, this pinion is aimed at hobbyists who want a resilient, low-mass gear. It is compatible with Tamiya vehicles that use 04 Module gearing, offering straightforward fitment across many kits.

Installation tips and included hardware

A 3mm grub screw is included to secure the pinion on compatible shafts. Installers should check gear mesh and motor load after fitting to ensure smooth running and to avoid premature wear.
