Trailing Arms - Rear Upper 68-72 GM A&G-Body

The Trailing Arms - Rear Upper 68-72 GM A&G-Body by QA1 is designed for builders and restoration specialists working on classic Chevrolet muscle cars and mid-size platforms from the late 1960s through early 1970s. These upper trailing arms are essential for upgrading vehicles like the Chevelle, Cutlass, Skylark, or Tempest, providing modern suspension geometry and improved handling characteristics.

Manufactured to precise tolerances, QA1's trailing arms incorporate robust pivot points that can handle increased loads and suspension articulation without deflection or play. The upper arm geometry is crucial for controlling rear axle tracking and rear-wheel camber, which directly influences tire contact patch consistency and anti-squat characteristics during acceleration. This design ensures that the arms integrate seamlessly into A-Body and G-Body frame configurations while maintaining OEM mounting points.

Enthusiasts restoring or restomodding 1968–1972 GM A&G-Body vehicles will find these trailing arms beneficial for enhancing performance on both street and strip applications. The design accommodates both bolt-in installation and aftermarket coil-over or leaf-spring systems without modification to the core frame structure, making it a versatile choice for various builds.
