The UMI 4023CM double-adjustable lower control arms for 1964–1972 GM A-body applications use 4130 CrMo construction and high-load Teflon-lined rod ends for race-capable durability. They allow one inch of length adjustment in either direction and come pre-set to factory length. CNC machined aluminum step bushings, in-house CrMo adaptors and TIG welds ensure strength while the finish provides an attractive, long-lasting look.
