QA1’s bolt-on 1979-1993 Mustang LS 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. Designed to work with LS engines, this k-member makes your LS swap easy!
