Housing Ball Joint Lower Screw In K719

The QA1 Housing Ball Joint Lower Screw In K719 is a precision suspension component engineered for vehicles requiring greasable, removable ball joint assemblies. This screw-in style housing accepts a 1.438-inch diameter ball stud and delivers the adjustability and serviceability demanded by high-performance suspension builds. Built from steel with zinc plating, it provides the durability needed for both street and competition applications where suspension geometry tuning is critical.

The screw-in design allows for precise installation and removal without specialized tools, making it ideal for chassis builders and suspension technicians who need repeatable adjustments. The 1.438-inch ball stud diameter is a standard specification in modern lower control arm assemblies, ensuring compatibility with commonly available ball stud components. The greasable design enables long-term maintenance in field conditions, extending the service life of your suspension geometry and reducing the frequency of full component replacement during extended use or frequent setup changes.

This ball joint housing is essential for street rods, race vehicles, and custom chassis projects where lower control arm geometry requires frequent adjustments or component swaps. Builders working on independent front suspension systems, performance street cars, and competition chassis depend on this type of removable housing to achieve precise caster and camber settings without replacing the entire ball joint assembly. The QA1 K719 is a direct replacement component for applications originally equipped with screw-in lower ball joint housings and is a critical element in any suspension system prioritizing tunability and long-term serviceability.
