UMI heavy-duty tubular rear lower control arms for 1982–2002 GM F-Body applications replace weak factory stamped arms with CNC-machined, TIG-welded DOM tubing and Energy Suspension polyurethane bushings. On-car adjustability centers aftermarket rear ends and gains tire clearance; an optional 4130 Chromoly version uses 1.250" x 0.095" tubing for reduced weight and higher tensile strength.
