Suspension Air Bags, found within the Suspension & Steering > Strut & Spring sections, provide a pneumatic springing solution for passenger cars and commercial vehicles. These robust, flexible components replace traditional steel springs, offering adjustable ride height and improved ride comfort. Air bags are commonly used in applications requiring load leveling, such as rear suspension systems in trucks and luxury passenger vehicles. They consist of a reinforced rubber or polymer bladder designed to withstand high pressures and constant flexing. Examples in our catalog include options for Mercedes-Benz Trucks, Mercedes-Benz Passenger cars, and high-quality replacements from Febi like FEBI102378 and FEBI20661. Proper air bag function is critical for vehicle stability and handling.
