Tamiya-style Mini 4WD Cuboid Mass Damper 9g - M4WD-39/GO by 3Racing  [M4WD-39/GO]

Compact 9g cuboid mass damper M4WD-39/GO for Mini 4WD setups

This single-piece 9g cuboid mass damper is supplied in a gold finish and sized for common mass-damper mounting points on Tamiya-style Mini 4WD chassis. The item is presented as an accessory component for builders and collectors rather than a performance guarantee.

Builders who work on tight layouts will find the concentrated mass useful when space is limited. The block form lets you add predictable inertia at a chosen chassis spot, aiding repeatable trimming around the centreline or other balance points.

The part is compatible with mainstream Mini 4WD configurations that accept aftermarket dampers; always check clearance and mounting on your specific chassis before fitting. Typical installation uses a dedicated slot, bracket, or small fasteners depending on your chassis layout.

Exact material treatments and precise mounting dimensions are not listed here; treat this as a simple tuning accessory and confirm fitment during installation.
