Pink M6.4 x 1.7 Ball Bearing Spacer for Mini 4WD

This pink M6.4 x 1.7 ball bearing spacer made for Tamiya Mini 4WD is produced by 3Racing and helps refine wheel rotation by keeping bearings aligned and reducing unwanted play. It is a small but effective part for builders who want smoother rolling and steadier handling on race lanes.

Fitment and How It Works

The spacer is sized to sit between the bearing and hub, cutting down on friction that slows wheel spin. It fits a broad selection of Tamiya Mini 4WD chassis and is suitable for racers tuning their cars for consistent lap times without complex modifications.

Track Benefits and Practical Use

On the track, using a spacer like this can translate to cleaner acceleration and fewer speed losses through corners. It helps maintain wheel alignment under load, which supports control during aggressive line changes and prolonged runs.
