An air suspension has been developed to meet the needs of the Class 8 truck market of the 1980's. This design was developed to satisfy a list of objectives that conform to present and future requirements for a tandem axle rear suspension. Throughout the development program, exhaustive tests were conducted to assure successful performance and minimize the possibility of last minute tooling changes. Dual anti-sway bars contribute significantly to the dynamic performance characteristics of this suspension and, along with the full air springing, represent its most significant performance features.
