This is a heavy-duty rolling lobe air spring, commonly called an air bag, used in truck and trailer air suspension systems. It replaces conventional leaf springs to provide a smoother ride, automatic load leveling, and adjustable ride height. Air springs like this wear out over time due to rubber degradation, air leaks, or damage, and should be replaced in pairs to maintain proper suspension balance.
