Ditch those clunky leaf springs and take control of your 1971-1981 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 AGRESSIVE 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 AND 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. This results in a significantly more aggressive stance and improved traction and performance. Note: Achieving maximum wheel and tire width will require mini tubs. IMPROVED HANDLING AND STABILITY QA1 4-link delivers handling control without compromising your daily comfort. Single-adjustable Proma Star shocks let you fine-tune the ride, effortlessly switching between smooth cruising and a firmer, more aggressive feel. EASY, INSTALLATION AND ADJUSTMENT Thoughtful design meets effortless installation requiring minimal welding. You'll experience a painless installation and setup process, where adjusting ride height, pinion angle, or wheelbase is as simple as a few tweaks – no link removal required. Note – Welding required. MADE IN THE USA QA1 suspension is proudly made in Lakeville, Minnesota. 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.

Manufacturer's Warranty — QA1

QA1 warrants this product to the original purchaser to be free from defects in material and workmanship for one year from the date of sale. A separate limited lifetime warranty covers only QA1's select shock and strut lines (Stocker Star, Proma Star, Ultra Ride and Aluma Matic) and requires registration at QA1.net/Warranty within 30 days of purchase. QA1 makes no other warranty, express or implied. Coverage does not apply where the defect results from improper or abnormal use, negligence, vehicle accident, incorrect installation or maintenance, or where the product has been repaired or altered in any way. QA1's liability is limited to repair or replacement of the defective product at its option; consequential and incidental damages are excluded. A claim needs an RMA number issued by QA1 — tag each item with the part number and a description of the defect — and the customer pays shipping to QA1 for inspection.

Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by QA1. Contact us if you need help with a warranty claim.
