The Tamiya 54577 - 06 Module Hard Coated Aluminum Pinion Gear (21T) is manufactured from lightweight aluminium with a hard coating to resist abrasion. That combination keeps rotating weight down while offering increased surface protection against normal gearbox wear.
The engineered rounded tooth form reduces contact stress and lowers friction between pinion and spur. This smoother engagement helps maintain consistent performance and reduces noise in the drivetrain.
Built to pair with 06 Module spur gears, this pinion includes a 3mm grub screw to lock it in place. Correct mesh adjustment and a firm grub screw ensure dependable running across different setups.
