As vehicle weight shifts, changes in internal pressure allow the suspension to respond by raising or lowering ride height accordingly. This interaction occurs continuously during operation and responds to road inputs, cargo variations, and chassis movement. During installation, the air spring is positioned between suspension mounting points and connected to the air supply. Designed for wide-temperature exposure and consistent service use, the Firestone W013589373 is part of the suspension assembly.
