3Racing M4WD-38/PK pink aluminum shaft stopper for Mini 4WD axles

This aluminum shaft stopper is a compact retention part intended for Mini 4WD axle assemblies. Machined from anodized aluminum, the pink finish aids part identification during build and maintenance. The piece is intended to locate and secure straight axles in standard Mini 4WD wheel hubs and roller positions without altering chassis geometry.

Compatibility is editorially noted: the stopper fits common Mini 4WD axle diameters used across mainstream performance chassis. Hobbyists should confirm axle and hub clearances on their specific MA, MS, AR, FM-A or Super-II based builds before installation. The description focuses on form and fit rather than performance claims.

Packaging and mounting interfaces vary by maker; the part is best treated as a spare or aesthetic replacement rather than a functional upgrade in isolation. For collectors, the anodized color provides a visible detail that matches other colored aluminium parts in a parts set.
