As air pressure increases, the spring expands vertically to raise the chassis, and as pressure is released, the spring contracts to lower the ride height. This action repeats continuously as road conditions and load demands change. The spring remains secured between mounting points while allowing vertical motion. Adjustment occurs automatically through the air suspension system without driver input. The spring cycles through expansion and compression during vehicle movement. The Firestone W013589978 manages suspension height through air-controlled movement.
