This aftermarket gear pack contains CNC-friendly brass gears sized to replace internal gearbox components on the listed TAMIYA tractor truck models. The parts provide a mechanical method to influence gear train behaviour while leaving motor and electronic systems unchanged.
These brass gears are intended for hobbyists seeking measured changes to gearbox response and effective gearing. Correct installation requires gearbox access, verification of shaft runout and bearing condition, and careful gear mesh setup to ensure reliable service life.
For precision-oriented builders focused on gearbox tuning in compatible TAMIYA tractor trucks, these brass gears provide an engineered replacement; ensure shaft alignment and correct mesh when fitting.
