The king pin serves as the pivot point which attaches the wheel spindle to the axle beam and is considered to be the most critical component of the axle assembly. It provides the means for the drag link, in connection with the steering arm, to change the lateral movement into turning motion.

\n\n

Since the king pin is the very heart of the axle assembly, it is mandatory for a replacement part of this nature to be of the highest quality. All Dayton Parts pins utilize high quality steel and are heat treated for superior strength and long service life. A satin smooth micro-finish insures minimum steering effort yet retains the ability to hold grease for proper lubrication.
