It acts as a pneumatic cushion that absorbs road shock, maintains ride height, and supports vehicle weight while protecting cargo and chassis components. Air springs like this one wear out over time due to material fatigue, cracking, or accidental punctures; when they leak or fail, the vehicle may sag or ride roughly. Replacing the worn bag restores proper suspension performance and load support.
