AGENT 47's 2005-2010 Mustang K-Member fits stock strut suspension set-ups and also, our double a-arm suspension. This product will shave nearly 20 pounds off the front of your car, by removing your stock K-member and installing this one. The resulting increase in chassis stiffness allows your suspension to work better, and you also receive more clearance for headers, turbo plumbing and other upgrades.
