    QA1 R357-170 Features:

    Upgrade your 1970-1981 2nd Gen GM F-Body by replacing those outdated leaf springs with QA1’s coilovers and triangulated 4-link system.

    • Includes spanner wrench
    • Optimized ride height that improves handling, roll center, and center of gravity
    • Designed to work with both standard and mini-tubs (Achieving maximum wheel and tire width will require mini-tubs)
    • Double adjustable shocks provide independent rebound and compression tunability - Perfect for both street and track use

    QA1 R357-170 Notes:

    • Typical ride height range from axle centerline to fender arch is 10.75 in. to 12 in. for Camaros and 13.75 in. to 15 in. on Firebirds
    • Wheel and tire fitment should be verified on the vehicle
    • Exhaust modification is required - It will not work with over-the-axle exhaust
    • Welding is required
    • QA1 Subframe Connectors strongly recommended
    • Transform Your Rear Suspension with QA1

      Enhance your hot rod’s performance by swapping out those old leaf springs for a QA1 Rear Four-Link Suspension System. Experience a smoother ride, sharper handling, and the freedom to fine-tune your stance. Plus, gain the clearance for wider wheels and tires—making this the ultimate upgrade for your build.
