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

Mini 4WD Pink Spacer M6.4 x 1.7 for Improved Wheel Rotation

Made by 3Racing for Tamiya Mini 4WD cars, this pink M6.4 x 1.7 ball bearing spacer helps keep bearings concentric and reduces rubbing inside the wheel stack. It is aimed at hobbyists who want a tidy, low-friction setup without complex mods.

Design Purpose and Fit

The spacer is intended to sit between the bearing and hub to lower internal friction and protect bearing faces. It fits a number of Tamiya Mini 4WD chassis styles and supports both casual builds and race-oriented setups.

On-Track Impact and Practical Gains

Using a properly fitted spacer can lead to steadier acceleration and better corner exit control. While not a dramatic upgrade by itself, it contributes to consistent lap times when combined with other tuning steps.
