3Racing M4WD-03/PK Pink Ball Bearing Spacer - Tamiya Mini 4WD M6.4 x 1.7 (Racing Grade)  [M4WD-03/PK]

3Racing M6.4 x 1.7 Pink Spacer for Mini 4WD Bearings

The 3Racing M4WD-03/PK pink spacer is a precision component for Tamiya Mini 4WD bearing stacks. It ensures concentric bearing placement and reduces axial contact points that cause drag, helping to stabilise rotational dynamics during high speed runs.

Engineering and Compatibility

Manufactured to tight dimensional tolerances, this spacer interfaces cleanly with standard Mini 4WD hubs and bearing types. Its role is to preserve bearing alignment under lateral loads while maintaining minimal clearance to avoid binding.

Tuning Advantages for Competitive Use

In a race setup the spacer contributes to reduced mechanical losses and steadier wheel behaviour during acceleration and corner exit. It is a simple, low-mass upgrade that complements bearing selection and chassis geometry for measurable consistency improvements.
