Mini 4WD Shaft Stopper Red - M4WD-38/RE by 3Racing  [M4WD-38/RE]

M4WD-38/RE single-piece aluminium stopper for Mini 4WD

This single-piece aluminium shaft stopper is a service replacement for Mini 4WD drivetrains. It is a compact locator designed to hold axle shafts in typical 4WD arrangements found on many performance-oriented chassis. The red anodized finish provides light corrosion protection and a consistent colour match with other anodized parts.

Compatibility guidance: the stopper is offered as a generic shaft locator suitable for Tamiya-style Mini 4WD axles. Correct fit depends on axle diameter, the shoulder position on the axle, and space taken by rollers or bearings. Builders should verify axle measurements and clearance where the stopper will seat.

Fitment and installation: position the part against the axle shoulder and rely on the chassis retention method (clip, nut, or press-fit) to secure it. Minor filing or subtle adjustment may be needed for modified axles; do not force the part onto the axle to avoid damaging shafts or nearby rollers.

Care and service life: anodized aluminium resists mild corrosion but can scratch if abraded. Clean track residue and dust periodically and inspect the seating face for deformation. Replace the stopper if it allows axial play.
