The Tamiya 42225 RC TRF 04 Module Pinion Gear (26T) is a precision part aimed at improving drivetrain flow. Crafted from hard-coated aluminium, its rounded teeth reduce contact friction and help maintain steady power delivery during spirited running.
This pinion fits TRF416, TRF417 and F1 cars that use 04 module spur gears. It is useful for enthusiasts dialing in ratio changes or replacing worn pinions without altering spur gear specification.
