The Firestone air suspension system main component are the air springs. The air springs in the air suspension systems are built to take a beating, but they are moving mechanical parts, and eventually all moving mechanical parts will fail. If this happens to you, don't worry, Firestone offers replacement springs for all of their air suspension systems. These air springs are as easy to replace as the original springs were to install. The replacement Firestone air springs can also be utilized in custom air spring applications.
