It uses compressed air to support the trailer’s weight and cushion road shocks, providing a smoother ride and protecting cargo. Over time, the rubber bladder can crack, leak, or delaminate, leading to sagging, uneven ride height, or bottoming out. Replacing it restores proper suspension performance and ride quality.
