The UMI tubular rear upper control arm for 1967–1970 GM B-Body is a direct bolt-on upgrade that strengthens rear suspension, reduces traction loss and minimizes wheel hop. It uses 1.750" x 0.120" DOM mild steel tubing, CNC-machined bushing holders, grease-able polyurethane bushings and TIG-welded construction with a durable powder coat. Sold individually; confirm whether your vehicle has one or two uppers and whether it’s a 3-link or 4-link setup.
