UMI tubular non-adjustable upper control arms with Roto-Joint for 1968–1972 A-Body applications use a greaseable delrin-lined pivot ball to allow 28 degrees of rotation for bind-free suspension movement. The Roto-Joint pairs a hard-chrome 4140 chromoly ball with a Delrin race for reduced wheel hop and improved traction, while 1.500" x 0.120" DOM tubing and CNC-machined plates deliver robust, direct bolt-on construction.
