More than seventy years ago, Firestone started developing a full air-based suspension for passenger cars. Firestone Airide air springs were installed on the new line fo general Motors buses in the late 50's. Later that decade, air springs began to gain popularity in luxury vehicles. Over the next 20 years, technology improvements in other suspension components, such as compressors and valves, helped support the growth of air suspension. In the 1970's, Ford Motor Company incorprated air suspension in the Lincoln Town Car and Continental. Firestone has continued to be innovative in product design, material selection and customer service, prviding our customers with improved ride quality and safe load-carrying capabilities.
