The M4WD-02/LB kit supplies light blue 4mm hex posts intended as direct-fit replacement parts for Tamiya Mini 4WD chassis where standard 4mm hex mounts are used. These components are specified for consistent seating and appearance in maintenance and restoration workflows.
Installers should verify receptacle diameter, axial clearance and head clearance prior to assembly to ensure correct engagement. The finish is primarily visual; if corrosion resistance or surface hardness is a concern confirm surface treatment with the supplier.
These parts are intended as maintenance spares and visual matches rather than structural race upgrades. For performance tuning choose components that document material grade and machining tolerances.
