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

Compact 9g cuboid M4WD-39/PK for Mini 4WD

This pink 9 gram cuboid is supplied as a replacement mass damper for builders tuning Mini 4WD 4WD chassis. Its compact rectangular form helps with precise weight placement in tight spaces and short damper stays commonly found on performance builds.

Intended for experienced modders: the item is a single accessory weight rather than an assembly kit. Since mounting interfaces vary between chassis types, verify hole spacing and clearance before final installation. Avoid altering fastener geometry that could unintentionally stiffen or soften the chassis response.

Use guidance: the cuboid works with chassis that accept added mass dampers to refine stability; it is not a drivetrain or electronic upgrade and should not replace purpose-made tuning components for other Mini 4WD series.
