UMI rear upper control arms for 1973–1977 GM A‑Body vehicles are heavy‑duty, non‑adjustable replacements that reduce suspension deflection and wheel hop for improved handling. CNC‑machined components, MIG‑welded bushing holders and 1/4" thick laser‑cut mounting pads provide strength, while greaseable polyurethane bushings and a durable powder coat deliver low maintenance and a bolt‑in install in about an hour.
