UMI Performance's adjustable extended-length upper control arms help eliminate wheel hop, add traction, and sharpen handling on the 1991-1996 Chevrolet Impala SS and Caprice, all with a bolt-on installation. The arms offer on-car adjustability and come fitted with spherical Roto-Joints. Each Roto-Joint is a pivot ball lined with a greaseable Delrin race that allows up to 28 degrees of unrestricted movement for low-friction, bind-free operation. Compared with factory rubber or aftermarket polyurethane bushings, the Roto-Joint lets the suspension articulate correctly for precise handling, while the Delrin race absorbs shock and road noise for quiet, smooth operation on the street or track. The arms ship fully assembled and ready to install using OEM hardware.
