The UMI boxed lower control arm for 1964–1972 A-body applications uses Roto-Joint technology to deliver bind-free articulation and a quiet, comfortable ride. Built from 3" x 1-1/2" rectangular steel tubing with CNC-machined bushing holders, TIG/MIG welds and reinforced sway bar sleeves, the arms reduce flex and wheel hop. Delrin-lined, greaseable Roto-Joints provide 28° of movement and ship assembled with a durable powder coat finish.
