This QA1 tubular K-member is a bolt-in swap for the factory K-member on the 1996-2004 Ford Mustang 4.6L, built for weight savings and improved geometry. All mounting points are digitally indexed from new factory K-members, and it is made from American-made HSLA steel at about 25 lbs, over 50 percent lighter than stock. It increases header and oil pan clearance, uses a modular design with bolt-in engine mounts that can be swapped for future engine changes, and maintains optimum anti-dive geometry while reducing bump steer on lowered cars. It retains the factory wheel base, and QA1 control arms are strongly recommended for best results.
