King 30310-100 King Pin Set with Bushings and Hardware

The King 30310-100 is a complete king pin rebuild set designed for heavy-duty steering knuckle applications. This comprehensive kit includes everything needed to rebuild and replace worn king pins, restoring proper steering geometry and front axle performance.

Complete Kit Includes:

• Two king pins with .010 inch oversize diameter for worn knuckles
• Four brass bushings for upper and lower installation points
• Thrust washers and bearings to handle vertical loads
• Threaded lock pins, welch plugs, and retaining hardware
• Assorted shims for proper clearance adjustment
• Lock washers and nuts for secure installation

This king pin set features straight-type pins machined to precise specifications. The brass bushings provide excellent wear resistance and lubrication retention, while the included thrust washers handle the axial loads generated during steering and suspension travel. The .010 inch oversize pins allow for proper fitment in knuckles that have experienced wear beyond standard tolerances.

King pin sets are critical steering and suspension components that connect the steering knuckle to the front axle beam on solid front axle vehicles. When king pins wear, they create excessive play in the steering system, causing poor handling, uneven tire wear, and potential safety issues. This complete rebuild kit restores tight tolerances and proper function.
