The Tamiya 54476 Ball Bearing Set is a straightforward upgrade for TT-02 owners wanting reduced drivetrain drag and smoother rotation. Replacing factory plastic bushes with bearings helps the model accelerate cleaner and puts less stress on motor and gears.
Lower friction means less wasted energy, better throttle control and reduced heat build up in moving parts. For off-road or mixed-surface running this can translate into more reliable, predictable handling.
The set supplies every bearing required to swap out the TT-02's original bushings:
When installed these bearings help the whole drivetrain spin more freely and resist wear from dust and frequent runs.
