Suspension builders around the world use Firestone trailer air springs. Why? Because Firestone Industrial Products has been advancing air suspension technology for more than 80 years. Our commercial trailer suspensions and air springs are challenged, tested and proven every day on thousands of trailers all over the world.
The Firestone story dates back to the early 1930s when we worked to perfect the pneumatic spring. Air spring systems were adopted by one of the country's largest manufacturers of motor coaches in 1938 and by 1950, the success of air springs in bus applications spurred new interest in truck and trailer applications. Today, many of the trailers on the road ride on Firestone trailer air springs, also called air bags.
