SPC's upper adjustable control arm for 1955–1957 Tri-Five Chevrolet applications offers the company's patented adjustment and improved clearance. Sold as a pair, these forged arms use 1/2" taller ball studs to enhance camber curve, feature greaseable and rebuildable ball joints, and are compatible with OE-length or 1/4" extended studs for ride tuning. They are intended to modernize handling for Pro Touring, track-ready, or daily-driven classic builds.
