It replaces the traditional steel leaf spring, using compressed air and a flexible rubber bellows to support the vehicle's weight. By absorbing road shock and vibration, it provides a smoother ride and helps protect cargo and chassis components. You typically replace these when the rubber bellows becomes cracked, leaks air, or the internal piston wears out, leading to a sagging suspension or a rough ride.
