    Specifications:

    Manufacturer's Part Number:
    MUK21

    These QA1 suspension parts for Mustangs are some of the most advanced ever designed. Reducing the weight is one of the keys to go fast, moving weight from your Mustang is the best place to start. By design, Mustangs are nose heavy which causes issues with cornering and acceleration. QA1 offers a strong, well engineered and reasonably priced solution to cutting the weight on your Mustang to make it accelerate faster, and handle better.

    Tubular K-Members
    Designed to reduce weight (up to 28 pounds), increase strength, improve geometry, and bolt-in replacement, QA1's Tubular K-Members' mounting points have been digitally indexed from new factory pieces. Other highlights include a greater header and oil pan clearances for easier installation and maintenance; improved bump steer, anti-dive, interchangeable motor mounts for Ford or Chevy engines and Ackerman angles for maximum performance; black powder-coated for durability; and the use of stock or aftermarket A-arms.

    Engine Mounts and Cross Members
    Featuring a High Strength Steel Construction and Powder Coated Finish for great durability and corrosion resistance, they are interchangeable depending on your applications needs. Cross Members include a long-lasting polyurethane transmission mount for superior performance.

    Street Tubular Control Arms
    Street Tubular Control Arms are a perfect choice for street and strip use. They are built with QA1's exclusive compressed rubber bushings and engineered for performance.

    Race Tubular Control Arms
    These control arms use QA1's exclusive heat-treated Chromoly, PTFE/Kevlar-lined, XM Rod ends. Spacers are included to allow forward and backward arm movement for wheelbase adjustment.

    Features:

    • Header and oil pan clearance maximized for easier maintenance and installation
    • Bolt-in engine mounts that can be easily swapped out for future engine changes
    • QA1 K-Members are 50% lighter than the stock K-member
