The Tamiya 42265 TRF 04 Hard Coat Aluminum Pinion Gear (35T) is a straightforward upgrade for hobbyists wanting a lighter pinion that still resists wear. Machined from lightweight aluminum and given a hard coat finish, it helps keep gear engagement consistent under demanding conditions.
The hard coat treatment increases surface hardness to extend service life while the precision-cut teeth reduce friction loss, resulting in reliable power transfer and smoother running at speed.
Made for Tamiya 04 Module gears, this pinion fits many Tamiya on-road and touring models. It includes a 3mm grub screw for secure mounting and installs easily with basic tools used for pinion adjustments.
