The 4-link bars provided in the kit were installed. There will be four 4-link bars and one pan-hard bar. Once the link bars were attached, we installed the pan-hard bar. It was bent to clear the center section of the rear differential, and we attached it with the bend to the rear.
The pan-hard bar is set at 33 ½ inches before it’s shipped, but you might need to adjust it to center the axle at ride height.
