QA1 R258-170 Rear Four-Link Suspension System for 1968-1972 Chevrolet Chevy II/Nova and Pontiac Ventura

Fits 1968-1972 Chevrolet Chevy II, Nova, and Pontiac Ventura.

Replace restrictive factory leaf springs with the QA1 triangulated 4-link suspension system to transform the handling and stance of your GM X-Body. This conversion provides precise axle control and enables +2 to -3 inches of ride height adjustability, allowing you to achieve a custom stance without compromising ride quality. The tubular design increases chassis rigidity and creates the necessary clearance for significantly wider wheel and tire combinations.

The system features QA1 double-adjustable shocks, providing independent control over compression and rebound settings for fine-tuned performance on both the street and the track. Installation is engineered for efficiency, requiring minimal welding and zero modifications to the factory floor pan. While designed for generous clearance, achieving maximum tire width will require mini-tubs.
