The Firestone Air Suspension Spring adjusts suspension height by expanding and contracting through controlled air pressure. As the load increases, air volume changes to raise or lower the chassis accordingly. This adjustment happens automatically as driving conditions shift. The spring allows vertical suspension movement while maintaining axle alignment. Routine inspections verify condition, and replacement restores proper suspension response. Use of air springs influences towing and hauling behavior by balancing weight distribution. The Firestone W013589781 contributes to air-based suspension adjustment during operation.
