The Tamiya 42268 TRF 04 Hard Coated Aluminum Pinion Gear (38T) is a reliable option for hobbyists seeking to refine gearbox efficiency. Its lightweight aluminium body helps lower inertia in the drivetrain.
The hard coating adds protection to the gear teeth for longer service between replacements. It is intended for applications using 04 Module gears, so it will work with Tamiya kits and other compatible setups.
