UMI Performance adjustable lower control arms for 1978–1988 GM G-Body applications use offset aluminum step bushings to move the arm inward 3/8" for extra tire clearance and mini-tub fitment. Built for race and light street use, they offer double adjustment, Teflon-lined spherical rod ends, DOM or optional 4130 CrMo construction, and TIG-welded fabrication for strength.
