The Tamiya Mini 4WD M6.4 X 1.7 Light Blue Ball Bearing Spacer - 3Racing M4WD-03/LB is a straightforward part for hobbyists aiming to tidy up wheel behaviour. It helps lower friction points inside the wheel stack to support steadier rotation.
Intended for compatibility with numerous Tamiya Mini 4WD chassis, this spacer reduces internal friction and aids uniform wheel spin. The light blue colour aids quick part selection during maintenance or pit changes.
When fitted correctly, the spacer can reduce subtle drag that hampers corner exits and lap consistency. It is a low-risk tuning option to complement tyre and setup changes.
