Product Overview Ditch those clunky leaf springs and take control of your 1970-1981 2nd Gen F-body with QA1's coilovers and triangulated 4-link. This upgrade improves ride quality, enhances handling performance, and enables you to dial in the perfect stance. With the added benefit of accommodating wider wheels and tires, this kit is the ideal solution for your car. Achieve a Lowered, more Aggressive Stance Leaf springs limit your ability to achieve the perfect stance and require modifications to tune ride height. Give your Camaro or Firebird a sleek, aggressive, lowered look with QA1's tubular 4-link. This kit provides an optimized ride height that improves handling, roll center, and center of gravity. QA1 coilovers offer height adjustability that can be dialed in with ease. Fit Wider Wheels & Tires Designed to work with both standard and mini-tubs, this system offers generous clearance for up to 12-inch-wide wheels and 335 tires. performance. Note: Achieving maximum wheel and tire width will require mini tubs. Ultimate Handling and Stability From twisty back roads to competitive track days, QA1's 4-link design with MOD Series shocks is the perfect solution for your F-body. 4-way adjustable valving offers independent tunability of both high and low speed compression and rebound. Easy, Installation & Adjustment Thoughtful design meets effortless installation requiring minimal welding. You'll experience a painless install and setup process, where adjusting ride height, pinion angle, or wheelbase is as simple as a few tweaks. Fitment Notes Typical ride height range from axle centerline to fender arch is 10.75 to 12 for Camaros, and 13.75 to 15 on Firebirds. Wheel and tire fitment should be verified on the vehicle. Exhaust modification required. Will not work with over the axle exhaust. Welding Required. Includes Spanner Wrench. QA1 Subframe Connectors strongly recommended.
