The TT02-13100_13115-LB replacement main shaft assembly is developed for the TAMIYA TT-02 1/10 scale chassis as a direct aftermarket drivetrain enhancement. The set couples an aluminium shaft with a steel joint to minimise wear where the shaft meets drive components and to offer greater stiffness than the original plastic pieces.
Installed as an affordable reinforcement in the gearbox area, the component helps stabilise the drivetrain when subjected to higher torque or more intensive use. The part is supplied in light blue and is intended solely for scale RC purposes.
Fitting is a direct swap for the standard TT-02 main shaft and joint; the design concentrates on correct fitment and alignment rather than altering ratios, so performance gains are primarily improved durability and reduced flex. Inspect adjoining parts and fasteners during fitting to ensure correct seating and smooth operation.
