Mini 4WD Mass Damper 6mm Ball M4WD-04/LB by 3Racing  [M4WD-04/LB]

6mm mass element M4WD-04/LB in light-blue for compact damper cartridges

This 6mm diameter sphere is intended as the movable mass within Mini 4WD mass-damper cartridges. It is supplied for technical users and tuners who service or replace small damping masses in standard Mini 4WD mounts.

The light-blue finish assists rapid identification when sorting mass sets during tuning sessions. Treat the ball as a serviceable component and inspect for dimensional integrity and surface defects prior to install.

Compatibility: engineered for common Mini 4WD mass-damper housings applied on 4WD chassis types including MA, MS, AR and Super-II that specify a 6mm movable mass. Verify bore clearance and retainer geometry of your cartridge before assembly to ensure unimpeded motion.

Handling and maintenance: store spare balls in a clean, dry container to avoid contamination. Do not expose to solvents or oils that may affect rolling friction. Replace any ball showing surface wear, flattening or reduced free-rolling characteristics.
