Mini 4WD axle shaft stopper M4WD-38/PK pink anodized by 3Racing  [M4WD-38/PK]

Pink M4WD-38/PK aluminum shaft stopper for Mini 4WD axles

This aluminum shaft stopper is a compact retention component designed for Mini 4WD axle assemblies. Machined from anodized aluminum, the pink finish makes the part easy to spot during assembly and routine maintenance. The piece is intended to locate and secure straight axles in standard Mini 4WD wheel hubs and roller positions without changing chassis geometry.

Fit guidance is editorial: the stopper suits common Mini 4WD straight axle diameters used by mainstream performance chassis. Builders should verify axle diameter and hub clearances on MA, MS, AR, FM-A or Super-II style builds before fitting. The text describes form and fit rather than making performance claims.

Packaging and mounting details differ by maker; treat this item mainly as a spare or a colour-matched cosmetic replacement rather than a standalone performance upgrade. For detail collectors, the anodized finish adds a visible accent that coordinates with other coloured aluminium parts.
