3Racing M4WD-38/RE aluminum shaft stopper for Mini 4WD assemblies

This aluminum shaft stopper is a spare part intended for Mini 4WD drivetrains. The component is a compact, single-piece stopper designed to locate and retain axle shafts in typical 4WD configurations used across common performance chassis. The red anodized finish provides basic corrosion resistance and a consistent visual match to other colored anodized parts.

Compatibility is editorially broad: the stopper is presented as a generic shaft-locating part for Tamiya-style Mini 4WD axles. Fit depends on axle diameter, axle shoulder placement, and the surrounding layout of rollers or bearings. Experienced builders should check axle dimensions and clearance in the area where the stopper will seat before committing to use.

Installation notes for hobbyists: the part is intended to be positioned against the shaft shoulder and secured by the existing retention method on the chassis (clip, nut, or press-fit arrangement). Light filing or minute adjustment may be required for precise alignment on modified axles; avoid force-fitting that can damage the axle or adjacent rollers.

Maintenance and longevity: anodized aluminum resists light corrosion but will scratch under abrasive contact. Periodic inspection and cleaning are recommended where dust or track residue accumulates. Replace if the seating surface shows deformation that could allow axial play.
