The UMI on-car adjustable lower control arms for 1982–2002 GM F-body applications pair spherical chromoly rod ends with a polyurethane chassis bushing to isolate road noise while preventing rear suspension bind. On-car adjustability is achieved via a heat-treated chromoly adjuster for easy tuning, and parts are CNC machined, fully TIG welded and powder coated, arriving fully assembled for bolt-on installation using OEM hardware.
