If you run a Tamiya TB-03 and want a durable upgrade, the Tamiya 54094 Aluminium Spur Gear Mount is a solid pick. Fabricated from aluminium with a blue treatment, it reinforces the drive area and gives a professional look trackside.
The aluminium construction replaces the weaker plastic part to increase longevity and improve gear alignment precision. That added stiffness helps maintain consistent mesh during corner exits and long runs.
Installation is straightforward on TB-03 models, with the mount dropping into place using the supplied four 3x5mm Phillips head screws. Tighten securely and recheck pinion mesh to prevent slippage.
