The Tamiya 42228 hard coated aluminum pinion is made for R/C users looking to improve drivetrain consistency. Its 04 module profile reduces friction losses and the hard finish helps resist wear during regular track sessions.
This pinion fits TRF models such as TRF416 and TRF417 plus F1 cars that use 04 module spur gears. It is a sensible upgrade for racers wanting crisper throttle response and dependable gear engagement.
