UMI on-car adjustable lower control arms for 1982–2002 GM F-body cars combine a spherical rod end with a polyurethane bushing to balance street comfort and responsive control. Adjustment moves the rear end for larger tires or to center aftermarket housings; changes are made on-car by loosening two jam nuts and turning the chromoly adjuster. CNC machined and TIG welded, they ship assembled and use OEM hardware for simple installation.
