Mini 4WD Balance Cuboid Mass Damper 9g M4WD-39/PK Pink by 3Racing  [M4WD-39/PK]

9g pink cuboid mass damper M4WD-39/PK

This 9 gram cuboid is a compact spare mass damper aimed at Mini 4WD enthusiasts who fine-tune balance and rebound on 4WD chassis. Its slim rectangular profile makes it suitable for narrow damper stays and spaces with limited vertical clearance.

Note for builders: this is sold as an accessory weight and not as part of a kit assembly. Because trim and mounting details differ across chassis, always dry-fit and confirm that fastener positions align before committing to permanent installation. Modifying mounting hardware can change chassis flex characteristics, so proceed carefully.

Practical compatibility: the cuboid is commonly used with higher-performance 4WD chassis that support added mass dampers. It does not replace motor, gear, or suspension tuning parts designed specifically for other Mini 4WD subfamilies.
