Mini 4WD Mass Damper Spare 6mm Ball M4WD-04/LB by 3Racing  [M4WD-04/LB]

6mm movable mass M4WD-04/LB in light-blue for Mini 4WD damper mounts

This 6mm ball is supplied as a compact movable mass for Mini 4WD mass-damper cartridges and mounts. It is intended for modelers and collectors who need to replace small damping elements in standard Mini 4WD assemblies.

The light-blue colour offers fast visual sorting when you keep multiple damping elements. Consider the ball a replaceable service part and inspect surfaces for wear or distortion before reassembly into a cartridge.

Compatibility advice: intended for conventional Mini 4WD mass-damper designs used on 4WD chassis families such as MA, MS, AR and Super-II where a 6mm damping element is specified. Always confirm the ball clears the retainer and slides freely within your housing.

Care guidance: store spares in a clean, dry box away from oils and chemicals that can alter surface friction. Replace any ball that loses its smooth rolling action or shows clear surface degradation.
