QA1 Ball Joint Stud for 1210-109 9029-227

A worn or damaged ball joint stud compromises your suspension's geometry and handling precision—exactly what you can't afford on track or in competition. This QA1 replacement stud restores proper alignment and steering response, ensuring your suspension geometry stays true under load. Whether you're running a dedicated race car or maintaining a high-performance street machine, a quality ball joint stud is critical infrastructure for safety and performance.

The QA1 9029-227 is engineered for direct fitment to QA1 control arms (1210-109 specification) and delivers the durability expected from a purpose-built suspension component. Black oxide finish resists corrosion, while steel construction handles the cyclic loads of aggressive driving.
