UMI Chromoly rear lower control arms for 1982–2002 GM F-Body applications use 1.250" x 0.095" 4130 steel to deliver increased strength and reduced weight. CNC-machined and TIG-welded, they include Energy Suspension polyurethane bushings and on-car adjustability for quick centering of aftermarket rear ends and added tire clearance, offering a lighter, stiffer alternative to mild steel tubular arms.
