Mini 4WD 2mm Spacer Pack M4WD-01/BK for Axles and Rollers by 3Racing  [M4WD-01/BK]

M4WD-01/BK precision 2mm spacers for Mini 4WD

This 2mm spacer kit from 3Racing serves as a simple fitment aid for Tamiya Mini 4WD builds. The spacers are designed to fit between axle components or below roller assemblies to fine-tune lateral clearance without permanent chassis changes. The guidance here assumes users have basic workshop experience.

Common applications include trimming small lateral play on standard axles, adjusting roller offset to avoid body contact, and matching spacing when swapping older parts. These spacers are consumable service items and do not modify gear ratios or drivetrain layout; they are compatible with typical Mini 4WD axles and rollers that accept separate spacer pieces.

Fit is affected by material and manufacturing tolerance, so trial-fit on the intended axle type before race use. Check competition rules for class compliance, as spacers can be regulated. The product is intended for maintenance and fitting rather than a performance enhancement for non-racing scale classes.
