UMI Performance 91-96 Impala SS Adjustable Extended Length Upper Control Arms- Poly Ends

The UMI Performance 3620-B control arms are adjustable extended length rear upper control arms with poly ends. They are designed to center the rear wheels in the wheel well on the Impala SS, extended 5/8” with additional adjustment for perfect centering, allowing the user to lengthen or shorten the control arms an additional 1/2” beyond the extended length. These control arms are built from DOM tubing with CNC machined mounting points and 4140 Chrome Moly tube adaptors. They feature a high strength 4140 Chrome Moly heat treated solid adjuster and include polyurethane bushings for quiet operation. They are designed to work with extended length lower control arms, and a longer driveshaft may be necessary depending on ride height variation.
