UMI extended upper control arms for 1991–1996 Impala SS add 5/8" factory-set length plus another 1/2" of on-car adjustment to help center the rear wheels. Constructed from DOM tubing with CNC-machined mounting points and a 4140 Chrome Moly adjuster, they use greaseable polyurethane bushings for quiet operation. Designed to work with extended lower arms; a longer driveshaft may be necessary depending on ride height changes.
