Mini 4WD Axle and Roller 2mm Spacer Set M4WD-01/BK by 3Racing  [M4WD-01/BK]

M4WD-01/BK 2mm spacers for Mini 4WD axle and roller clearance

This 2mm spacer set from 3Racing is supplied as a straightforward spacing accessory for Tamiya Mini 4WD assemblies. The small washers are intended to sit between axle elements or under rollers to dial in lateral clearance and alignment without cutting or reshaping the chassis. The notes below focus on practical use for experienced builders and collectors.

Typical uses include removing minor side play on stock axles, moving rollers slightly outward for body clearance, and keeping consistent spacing when replacing worn parts. As a basic service item, the spacers do not change drivetrain geometry and are compatible with common Mini 4WD axles and rollers that accept discrete spacer or washer components.

Material, finish, and manufacturing tolerance influence fit; test the spacer inner diameter against your axle or pin before committing to competition. For race eligibility and class rules, check event regulations since spacers may be handled differently by organisers. This item is presented as a maintenance and fitting component rather than a performance upgrade for scale or Wild/Scale Mini 4WD classes.
