The UMI tubular upper control arm for 1964–1967 A-body applications uses a delrin-lined Roto-Joint to allow 28° of free movement for quiet, predictable suspension articulation. Constructed of 1.500" x 0.120" DOM tubing with thick CNC-machined mounting plates and TIG welding, the arms are shipped fully assembled and finished in powder coat for direct bolt-on installation using OEM hardware.
