My truck had a consistent, strong pull to the left after installing this kit. After going through basically every part of the suspension and steering several times over, I found that the track bar drop bracket included was too short. It only dropped the bar by 1.75"", not the 2.25"" (actual) height of the rest of the kit. This resulted in my axle sticking out about 5/8"" to the left. Installing an adjustable track bar solved the problem.Not sure if they had sent the drop bracket for an older truck (part looks almost identical for 6.0 era trucks) or if it's a generic bracket shared with other kits.The rest of the kit performed as expected, and included all required nuts, bolts etc
