What's Included in the King Pin Kit?

 

A complete King Pin Kit typically includes (varies slightly by application):

 

Component	Quantity	Function
King Pin (steering pivot shaft)	1 Set	Vertical pivot connecting axle beam to steering knuckle
Upper & Lower Bearings/Bushings	1 Set	Reduce friction, allow smooth steering rotation
Thrust Bearings / Washers	1 Set	Absorb vertical loads
Oil Seals	1 Set	Prevent grease leakage and contamination
Dust Covers / Caps	1 Set	Keep dirt and moisture out
Lock Pins / Cotter Pins	1 Set	Secure components
Grease Fittings (Zerk)	1 Set	Enable lubrication

 

 

 

Product Function & Importance

 

 

 

The king pin is the pivot point around which the front wheels turn. A worn king pin kit causes:

 

• Excessive wheel play (loose steering)
• Uneven tire wear (especially inside edges)
• Poor return-to-center after turning
• Vibration or shimmy at highway speeds
• Clunking noise over bumps

 

Installing a new King Pin Kit restores:
✅ Precise steering response
✅ Stable straight-line tracking
✅ Even tire wear
✅ Safe vehicle handling
✅ Longer tire and steering component life
