The Hellwig 1" solid chromoly rear sway bar for 1978–1988 GM A/G-body vehicles is a factory-style handling upgrade engineered to reduce body roll and improve cornering control. It installs with simple hardware and uses increased diameter and precision components to deliver a significant handling improvement over stock. Designed for restored or performance-oriented A/G-body cars, the bar comes with a limited lifetime warranty and may require drilling.
