[More Info]

QA1’s bolt-on 79-93 Fox Body Mustang K-members are designed to enhance performance while significantly reducing weight. These K-members offer increased header clearance and improved Ackerman, anti-dive, and roll center geometry, especially on lowered vehicles. Additionally, modular engine mounts simplify engine swaps, including Coyote swaps.

LIGHTWEIGHT DESIGN

QA1's bolt-on Mustang K-members are constructed from high-strength, low-alloy (HSLA) steel, resulting in a design that is 50% lighter than a stock crossmember. This material allows for maximum strength and rigidity while minimizing weight. With engine mounts installed, the entire K-member assembly weighs in at a mere 23 pounds, dramatically reducing overall vehicle weight and enhancing performance.

EASY ENGINE SWAPS

QA1's Mustang K-member is designed to maximize clearance and offer engine mount adaptability to simplify your next engine swap. Whether you're working with a classic 5.0 Windsor or a modern Coyote, QA1 offers bolt-in engine mounts, ensuring a smooth and efficient installation process.

EASY, BOLT-IN INSTALLATION

Thoughtful design meets effortless installation, requiring no welding. Enjoy a painless process and get back on the road quickly.

MADE IN THE USA

QA1 suspension is proudly made in Lakeville, Minnesota.
