Instead of having the expense of buying a complete C5/C6 stock upper control arm to service the ball joint, Detroit Speed now offers replacement upper OEM ball joints to help save you cost on updating your 1997-2013 Corvette suspension. Each ball joint comes with hardware and the boots are permanently attached to protect against contamination and corrosion under any driving condition. Premium chassis parts are the only source Detroit Speed relies on for quality chassis steering replacement components.
