Aluminum Upper Control Arms for 63-82 Corvettes: Natural Finish, Performance Ball Joints
SpeedDirect's aluminum control arms greatly improve your suspension geometry which directly translates into improved handling and cornering ability. This kit provides increased positive caster for greater stability and improved bumpsteer, while relocating the front roll center for superior handling. They are also lighter than both stock and steel tubular control arms. Each side is 4 lbs less than the stock control arm, resulting in an 8 lb weight savings! Designed as a true bolt-on kit, these control arms do not require any modification to the vehicle. Kits are available in natural or polished aluminum finishes and come complete with clear instructions, bushings, cross shafts and optional ball joints. MADE IN THE USA!
