Ball Joint Stud +.500 for 1210-104/1210-205B

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. Whether you're rebuilding a stock suspension, upgrading a street machine, or maintaining a performance platform, this oversize stud compensates for wear and restores proper alignment geometry.

The +.500 designation indicates this stud is oversized by half an inch, 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 compact 1.38 x 1.38 x 4-inch envelope fits standard ball joint cavities while 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 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, making this component ideal for suspension rebuilds where geometry restoration and extended component life are priorities. Mechanics and fabricators specify QA1 ball joint studs when OEM replacements are unavailable or when custom suspension tuning demands superior fit and finish.
