UMI extended-length upper control arms for 1991–1996 Impala SS are shipped pre-set at 5/8" extended and offer an additional 1/2" on-car adjustability to perfectly center the rear wheels. Constructed from DOM tubing with CNC-machined mounts, 4140 Chrome Moly adaptors and a heat-treated 4140 adjuster, they use Teflon-lined spherical rod ends to reduce noise while providing quiet, precise articulation. Pair with extended lowers for best results.
