Tamiya 15437 - 13mm Aluminum Ball-Race Rollers for Mini 4WD (Ringless) - Precision Racing Part  [15437]

Summary of the Tamiya 13mm Aluminum Ball-Race Rollers

The Tamiya 15437 13mm Aluminum Ball-Race Rollers are intended to refine Mini 4WD handling. Produced from lightweight aluminum, they combine toughness with minimal weight. Each roller houses 520 ball bearings to ensure smooth rotation and reduce rubbing against track walls.

Compatibility and installation

These ringless rollers are suitable for front or rear applications across many Mini 4WD chassis. Their geometry helps retain speed and stability, supporting drivers who are tuning handling for competitive runs.

Effect on circuit performance

Lower friction from ball-race bearings promotes neater cornering and can contribute to quicker lap times on technical layouts. Reliable bearing construction maintains consistent performance through extended race use.
