566.ER9580

AIR BAG

This is a rolling-lobe air spring (air bag) used on heavy‑duty truck and trailer air‑ride suspensions, commonly found in Hendrickson walking‑beam systems. It supports the vehicle’s weight, absorbs road shock, and helps maintain proper ride height. When an air spring leaks, cracks, or the suspension sags, it should be replaced to restore ride quality and prevent component damage. The part is an aftermarket equivalent to several OEM air springs, including Firestone 9580 and Goodyear 1R13‑081.
