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

M4WD-01/BK 2mm spacer set for axle and roller clearance

The 2mm spacer set is a no-frills fitment part from 3Racing for use on Tamiya Mini 4WD platforms. These thin spacers slip between axle parts or under roller assemblies to tweak lateral clearance and help with alignment without altering the chassis. This copy is written for hobbyists who maintain or restore small 4WD cars.

Use cases include removing slight axle wobble, shifting roller position to clear bodywork, and establishing repeatable spacing when fitting replacement parts. As a basic spare, the spacers do not affect drivetrain ratios and are compatible with common Mini 4WD axles and rollers that accept separate spacer pieces.

Because tolerances and finish affect how the spacers fit, trial-fit them on the exact axle and roller type before relying on them in competition. Race organisers may have specific rules about added spacers, so verify legality for your class. The product is intended for maintenance and fitment tasks rather than outright performance conversion.
