The Tamiya 54476 Ball Bearing Set upgrades the TT-02 by swapping plastic bushes for precision bearings, yielding smoother rolling and lower mechanical resistance. This simple change helps the car respond more consistently under load.
Ball bearings cut friction at pivots and shafts, which reduces stress on the motor and gearbox. That can mean steadier lap times and fewer worn parts over extended running.
The pack includes all bearings needed to replace the TT-02 factory bushings:
Fitting these components gives the entire drivetrain improved rollover and better resistance to everyday wear.
