Indeed you do. The bracket will raise the track bar the correct amount to keep it parallel with the drag link and keep your steering as it should be. Don't confuse the adjustable track bars purpose, it is only to center the axle. The flip when used at 3"+ of lift places the drag link angle back to near stock and the tb bracket raises the track bar to match that. Combine all that with lower control arms and you can achieve factory geometry.
