Keep your heavy-duty steer axle pivoting tight and true with the Mevotech Supreme Steering King Pin Set MS95999. This front king pin set replaces the worn pivot pins, bushings, and hardware that connect the steer-axle spindle/knuckle to the axle beam, letting the front wheels turn smoothly. It's a direct-fit replacement for the front position on trucks including the 1996-2011 Freightliner Century Class, 1987-2023 Kenworth T800, and 1986-1998 Peterbilt 379 — see the Buyer's Guide tab for the full list of 27 applications across Freightliner, Kenworth, and Peterbilt.
Worn king pins can show up as steering wander, excessive play in the front wheels, hard or notchy steering effort, and uneven front tire wear. If worn king pins are the cause, this set replaces them.
