The QA1 upper screw-in ultimate ball joint for large Mopar applications is an adjustable, owner-rebuildable unit designed for upper locations. It uses a patented self-lubricating design to reduce friction and allows preload adjustment to achieve bind-free operation. Multiple stud lengths support geometry changes, and the rebuildable architecture means worn parts can be replaced economically without changing the housing.
