This aluminum main shaft is supplied by JAZRIDER as an aftermarket replacement for the Tamiya TT-02 chassis and is marked TT02-13100-BK. The black anodized finish offers a corrosion-resistant surface for drivetrain use.
It transmits torque between gearbox gears and can be fitted as a direct swap to restore worn parts or to provide a firmer aluminium option for tuned drivetrains.
Installation notes: replacing this shaft requires removal of the gearbox cover and inspection of mating components. Confirm correct bearing seating and gear mesh prior to final assembly to avoid binding or premature wear.
