UMI tubular rear upper control arms for 1978–1996 GM B-Body applications are a direct bolt-on upgrade built from 1.625" OD x .125" DOM mild steel tubing with CNC-machined 0.250" mounting plates. On-car greaseable polyurethane bushings, Zerk fittings and a durable powder coat finish reduce bushing deflection and wheel hop while improving cornering. Bolt-in installation takes about an hour using OEM hardware—no drilling required.
