The QA1 Pro Rear Coil-Over System is a complete bolt-in conversion designed to modernize your classic GM suspension. This kit replaces the factory separate shock and spring setup with a fully adjustable coil-over configuration, providing significant improvements in both handling and stance. The single-adjustable aluminum shocks feature 18 positions of simultaneous rebound and compression valving, allowing you to fine-tune your ride quality and performance with a simple knob adjustment.

Each kit features lightweight billet aluminum shocks with a fully threaded body for precise ride height control, ranging from 0.5 inches above factory height to a 2.25-inch drop. The included 150 lb/in high-travel springs are paired with vehicle-specific, USA-made mounting brackets to ensure a straightforward installation without the need for custom fabrication.
