Remove the U-bolts from the righthand spring pack. Also remove the plate that sits on top of the spring pack. Assemble the track-bar bushings and ensure that the track bar length ranges between 35.5 and 36.875 inches for 6- to 12-inch lifts respectively. Mount the new lower track-bar bracket on top of the righthand leaf pack and fasten down with the U-bolts supplied in the kit. Snug the U-bolts but do not tighten. In this photo, you can see the difference between the new lower track-bar bracket that doubles as the shock mount, and the stock plate.
