For RC hobbyists looking to sharpen drivetrain response, the Tamiya 42262 - TRF 04 Hard Coat Aluminum Pinion Gear (32T) is a sensible swap. Its low mass and precise cut help improve power transfer, making gear changes feel more direct on race day.
The TRF engineering applies a special hard coat to the aluminum surface to resist wear while keeping friction down. That combination helps maintain consistent power delivery during extended runs.
This pinion fits models that use 04 Module gears from the same manufacturer, so it is useful for racers who want measurable gains without major chassis changes.
