UMI adjustable rear upper control arms for 1978–1996 GM B-Body applications combine greaseable polyurethane bushings, CNC-cut mounting pads and a chromoly on-car adjuster for simple pinion angle changes. Built with TIG/MIG welds and chromoly threaded adapters, they improve handling and reduce wheel hop while installing in roughly 1–2 hours using basic hand tools. Durable powder coat finish protects the components.
