Restore precise, controlled steering on your heavy-duty front axle with the Mevotech Supreme Steering King Pin Set MS95987.

Signs the king pins may need replacing include steering wander, excessive play or looseness in the front end, uneven tire wear, and knocking or binding when turning. If worn king pins are the cause of these symptoms, this set replaces them. Diagnose the underlying condition before installing.
