It serves as the load-carrying cushion between the axle and the trailer frame, absorbing road shock to protect cargo and improve ride stability. It directly replaces worn, leaking, or cracked original air springs on a variety of common trailer makes. Installation restores proper ride height and load capacity, and is usually required when the existing bag shows deep cracking, rubber deterioration, or fails to hold air pressure.
