Ball Joint Stud for 1210-109

The Ball Joint Stud for 1210-109 by QA1 is a precision suspension component engineered for professional-grade vehicle control and handling refinement. This replacement stud serves as the critical pivot point in front-end ball joint assemblies, connecting the control arm to the steering knuckle with load-bearing reliability. Whether you're restoring a classic muscle car, maintaining a late-model performance platform, or upgrading aging suspension geometry, this ball joint stud delivers the durability and fitment accuracy your build demands.

Manufactured from hardened steel with a protective black oxide finish, the QA1 ball joint stud features a 2.000 in/ft taper, a 1.438 inch ball diameter, and a 1/2-20 inch thread for secure mounting compliance. The 3.641 inch overall length places this component in the standard-length category, ensuring correct suspension geometry and ride height without modification. Black oxide coating resists corrosion and oxidation while maintaining a low-profile appearance, and the tapered design accommodates OEM and upgrade ball joint cups across multiple platforms. Precision threading and spherical ball geometry minimize binding and promote smooth articulation throughout suspension travel.

This ball joint stud is ideal for rebuilds, wear correction, and performance suspension upgrades where OEM ball joint assemblies require stud replacement. Technicians and enthusiasts working on control arm assemblies, steering linkage, or front-end structural repairs will find this component essential for restoring proper wheel alignment and suspension compliance. Installation requires removal of the old stud and press-fitting the replacement into compatible ball joint cups; verify your specific vehicle application and ball joint cup specifications before ordering to ensure proper fit and load rating compatibility.
