TAMIYA BBX BB-01 Metal 86T Spur Gear BBX086TS by GPM  [BBX086TS]

86T medium carbon steel replacement spur

This 86-tooth spur gear is a direct replacement sized for the TAMIYA BBX BB-01 chassis. Made from medium carbon steel, the tooth profile increases wear resistance compared with the original nylon spur while matching BB-01 gear stack and mesh dimensions.

Choose this metal spur when you need a tougher alternative for routine tuning and durability upgrades; it is for model use only and does not imply any real-vehicle application. Always confirm gear mesh and pinion alignment during fitting to avoid premature wear on mating gears and bearings.
