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

M4WD-04/RE 6mm damper ball for 1/32 Mini 4WD mass-damper setups

This 6mm steel ball is supplied as a service spare for mass-damper assemblies used on 1/32 Mini 4WD cars. It is intended as a direct replacement for plain 6mm balls in mass-damper housings and is presented as a maintenance part rather than a performance tune.

Builders and collectors should check mating surfaces and retainer fit when swapping balls to avoid play or binding. The component comes in red; focus on roundness and surface finish when assessing long-term wear. Confirm the damper bore and retainer style before installation to ensure correct fit.

For experienced hobbyists: after fitting, rotate the damper to verify smooth motion and secure retention. If the assembly uses alternate damping media or bespoke retainers, confirm clearance rather than assuming a drop-in swap.
