The QA1 Double Adjustable Rear Four Link Suspension System is a complete high-performance upgrade that replaces the factory leaf springs on 1967-1969 GM F-Body vehicles (Camaro and Firebird).
This system includes QA1’s renowned double-adjustable coil-over shocks and a tubular triangulated 4-link, giving you full control over ride height, pinion angle, and wheelbase with simple adjustments no link removal required. It dramatically improves ride quality, handling, and traction while allowing significantly wider wheels and tires (up to 11" on 1967-68 models and 12" with 335 tires on 1969 models when mini-tubs are used).
The kit delivers superior stability for both street and track use, with independent rebound and compression tuning for precise suspension control. Installation requires minimal welding and no floor pan modifications. QA1’s best-in-class Lifetime Warranty (with registration) and USA-made quality ensure long-term reliability and performance.
