The Ball Joint Stud +.500 for 1210-104/1210-205B is a precision replacement component designed for high-performance suspension systems requiring exact geometry and load-bearing integrity. Built by QA1, a respected manufacturer of performance suspension hardware, this stud serves as the critical pivot point connecting control arms to steering knuckles in independent front suspension setups. This oversize stud compensates for wear and restores proper alignment geometry.
The +.500 designation indicates this stud has a diameter increase of 0.500 inches, allowing machinists to bore out worn ball joint seats and install a fresh pivot point without replacing the entire housing. QA1 manufactures these studs to exacting tolerances, ensuring consistent thread engagement, proper taper fit, and repeatable preload characteristics that eliminate play and wandering geometry. The precision-hardened stud resists galling and provides long-term durability under dynamic suspension loads, cornering forces, and brake torque inputs.
This stud is engineered specifically for 1210-104 and 1210-205B suspension systems, including many independent front-end platforms found in muscle cars, street rods, and performance street vehicles. Installation requires precise boring and honing of the ball joint cavity to accept the larger diameter stud. Whether you're rebuilding a stock suspension or upgrading a performance platform, this component is essential for maintaining optimal alignment and handling.
