QA1 70-81 GM F-Body Mod Series Four Link Suspension System

If you're looking to ditch the factory leaf springs on your 1970-1981 Camaro or Firebird and gain serious control over its handling and stance, this QA1 Mod Series four-link suspension system is a solid choice. This kit is designed to replace your old leaf springs with a modern, adjustable four-link setup, which fundamentally changes how your car handles bumps and corners. It's a significant upgrade that can really transform the driving experience, making it more predictable and enjoyable, whether you're cruising back roads or hitting the track.

What really sets this system apart is its ability to let you dial in the perfect look and performance. The included QA1 MOD Series coilovers offer adjustable ride height, so you can achieve that aggressive, lowered stance you're after. Plus, the design provides significantly more clearance, allowing you to fit much wider wheels and tires – up to 12 inches wide with 335mm tires, though mini-tubs are recommended for maximum fitment. The four-link geometry itself is engineered to improve the car's roll center and lower its center of gravity, leading to improved stability and handling. The MOD Series shocks feature 4-way adjustable valving, giving you independent control over both high and low-speed compression and rebound, so you can fine-tune the suspension for your specific driving needs.

Installation involves some welding, and you'll need to modify your exhaust system as it won't work with over-the-axle routing. QA1 also strongly recommends using their subframe connectors for the best results. Adjusting ride height, pinion angle, or wheelbase is straightforward once installed, making it easier to get everything set up just right.
