SPC adjustable upper control arms for 1963–1982 Chevrolet Corvette and 1965–1970 Impala applications are sold as a pair and feature a patented forged-steel design that offers extensive caster and camber adjustment. SPC uses a 1/2 in taller ball stud to improve camber curve; the arms include greaseable, rebuildable ball joints and support OE-length and extended-stud options to help modernize suspension geometry for pro-touring or track-ready builds.
