The M4WD-06/RE cylindrical weight is a compact 4.3 gram red spare designed for mass damper positions on competitive Mini 4WD platforms. Its uniform cylindrical geometry concentrates mass centrally, making it suitable for targeted tuning where minimal footprint is required. The item functions as a replacement or colour-matched spare rather than a complete damper subassembly.
Intended compatibility covers performance Mini 4WD chassis that accept mass damper inserts. In practice, technicians and racers test-fit these cylinders in MA, MS, AR, FM-A, VS and Super-II style mounts; confirm bore diameter and retention method before committing the part to race use. It should not be assumed compatible with Wild Mini 4WD or Scale Mini 4WD families without verification.
For installation verify the damper holder bore and retention type on your chassis. This part is defined by mass and form factor only, so ensure mechanical retention and radial clearance meet your damper architecture. The red finish aids visual identification and can support consistent parts management across team spares.
As a small, racer-focused spare, the cylinder is useful for quick replacements and maintaining repeatable setups between runs. Treat it as a tuning accessory rather than a structural upgrade.
