This QA1 bolt-in tubular K-member lets owners of 1979-1993 Mustangs run the engine of their choice while gaining weight savings, added header clearance and improved geometry. It is made from American-made HSLA steel, is over 50 percent lighter than the stock K-member at about 25 lbs, and retains the factory wheel base so it bolts on without wheel or tire fitment changes. It maintains optimum anti-dive geometry and reduces bump steer on lowered cars. Bolt-in engine mounts are sold separately, and QA1 control arms are strongly recommended for best results.
