Suspension airbags, also known as air springs, are components of an air suspension system that replace traditional coil or leaf springs in some vehicles. Made from durable rubber and reinforced with fabric, these airbags use compressed air to support the vehicle’s weight, adjust ride height and improve ride comfort. Air suspension systems are common in luxury cars, SUVs and commercial vehicles where smooth handling and load leveling are important. Over time, airbags can wear out, develop leaks or lose pressure, leading to uneven ride height, bouncy rides or warning lights on the dashboard. Replacing faulty suspension airbags restores comfort, stability and proper vehicle alignment.
