It replaces original air springs like the Firestone 8708 and Hendrickson S-21966, providing the air cushion that supports the trailer weight and absorbs road shock. A leaking or damaged air bag causes the trailer to sag or ride unevenly; replacing it restores proper ride height and load-levelling. This aftermarket unit features a plastic base and a reversible design that can be flipped to extend service life.
