UMI adjustable lower control arms for 1982–2002 GM F-body models use a chromoly on-car adjuster with spherical rod ends and polyurethane bushings to allow quick length changes for tire clearance or rear-end centering. CNC machined tubing and full TIG welding provide strength; these assemblies ship ready to install, use OEM hardware and are available in a chromoly option for increased strength with reduced weight.
