QA1's bolt-in K-members allow owners of 1979-1993 Mustangs to use the engine of their choice while enjoying the significant weight savings, increased header clearance, and improved geometry of a QA1 K-member. Made from high-quality American-made HSLA steel, this tubular design is over 50% lighter than the stock K-member, weighing only 25 lbs! Ideal for street performance, autocross, Pro-Touring or drag racing, these K-members maintain optimum anti-dive geometry and minimize bump steer issues on Mustangs with a lowered stance. And because they retain the factory wheel base, these K-members easily bolt on to factory components without any wheel or tire fitment changes. Bolt-in engine mounts sold separately. For best results, QA1 control arms are strongly recommended.
