They work with the factory kingpin style suspension. a disc brake kit is required since the backing plate will interfere with the new kingpin location. A shock relocation kit is also included. Welding required for the new upper shock mount. You will need a pair of Chevy PU shocks for this installation, we provide the application in the instructions so they can be bought locally. Your original steering arms  will need to be modified to maintain proper geometry
A kingpin rebuild kit is also recommended.
