Replace the flimsy factory live axle Mustang rear control arms with a set of these popular BBK rear lower control arms. Manufactured from heavy gauge steel plate using precision welds these BBK Performance heavy duty Mustang lower control arms will "Hook You Up" on the track and on the street. These rear control arm kits will greatly improve your ET's and 60ft times and best of all they are a direct swap for the factory units. These control arms will give you better handling and cornering characteristics because of their design and super stiff boxed steel tubing and polyurethane bushings.
