The UMI Performance adjustable rear upper control arm for 2005–2010 Ford Mustang replaces the factory stamped arm with a spherical Roto-Joint to improve traction and reduce wheel hop. Constructed from 1.250" x 0.120" DOM mild steel tubing, it’s on-car adjustable with a heat-treated chromoly adjuster, ships fully assembled and includes a spacer kit to correct oversized chassis mount holes and eliminate clunks.
