This is an air spring (air bag) for Hendrickson INTRAAX trailer suspension systems with 23,000 lb capacity and Zero Maintenance Damping (ZMD). It cushions the axle movement, maintains proper ride height, and absorbs road shock to protect the trailer frame and cargo. You would replace it when you notice air leaks, a sagging trailer, or uneven tire wear—common signs the air spring can no longer hold pressure or support the load correctly.
