UMI's fully boxed lower and adjustable upper rear control arm kit for 1964–1967 GM A‑Body pairs a factory look with reinforced performance. Fully boxed lowers use 3" x 1‑1/2" rectangular tubing with CNC machined radius ends and capped ends to prevent debris ingress. Adjustable uppers provide on‑car pinion angle tuning with CrMo adjusters; assemblies use greaseable polyurethane bushings and a durable powder coat, installing in about two hours.
