Compact overview for the Tamiya spacer

The Tamiya Mini 4WD M6.4 X 1.7 Light Blue Ball Bearing Spacer - 3Racing M4WD-03/LB is a small but useful part for hobbyists who want crisper wheel action. It helps stabilise axle rotation and is ideal for quick tuning at the bench or track.

Compatibility and how it works

Engineered to suit a wide range of Tamiya Mini 4WD chassis, the spacer reduces lateral play and lowers friction inside the wheel assembly. The light blue colour aids fast identification when organising spares for events.
