M4WD-05/LB is supplied as a single-piece 9.4g damper weight with a light-blue finish, intended for use as a spare or matched replacement in Mini 4WD mass-damper assemblies. This unit is specified by mass and finish to aid consistent tuning and setup replication.
The listing presents the quantifiable attributes only. Use the 9.4g mass to maintain predictable behaviour when swapping weights between mass-damper configurations or when documenting setup baselines.
Installation guidance: this is an aftermarket accessory compatible with typical Tamiya-style mass-damper fixtures; confirm damper post diameter and mounting method prior to installation to ensure correct mechanical engagement. No drivetrain or chassis alterations are implied.
