This Yokomo SD-304MSA kit is provided as a direct replacement for motor mount hardware used during drift package servicing and repairs on compatible RC drift chassis. The set helps restore motor mount tension and secures original mounting points with a selection of button head and flat socket screws sized to match typical factory lengths.
Fitment guidance: always check each supplied screw against the original mounting holes before final tightening, use the correct driver to avoid damaging the screw head, and position the spring following your chassis parts diagram so the mount retains the correct tension when loaded. The kit is intended for maintenance, repair, and as spares for drift-oriented assemblies.
