    Abstract: A leaf spring suspension system for a vehicle having spacers between the bottom of the No. 1 spring of the improved leaf spring suspension system and the top of the O.E.M. No. 1 leaf spring of the vehicle. Such spacers apply compression tension to the spring leaves as they contact thus acting as a spreader to keep the mounting hardware constantly in tension and preventing rattling and squeaking of parts.
