Product Features and Specifications

The TC5189 control arm assembly features a robust steel construction combining casting and forging processes to ensure structural integrity. The ball joint is machined and includes a threaded stud with a 0.47 inch (12.0 mm) thread diameter and a stud length of 3.31 inches (84.0 mm), providing secure mounting and reliable articulation.
