A few things that are different between this kit and some others.
1) The front upper control arm axle mounts require drilling out the bushing to fit the larger 7/16th bolt.
2) The front track bar requires drilling the frame mount to a 5/8th non-tapered hole.
3) There is two options with the axle side front track bar hole size. You can either go with the stock size hole or the 1/2" size hole. Nothing wrong with the stock size, plenty strong. But, you must specify and make sure a previous owner did not drill to the 1/2" hole size already.
1) The rear upper control arm axle mount must be drilled out to a 7/16th size hole. On a 44 and 35 those "holes" are square. But, you must drill them out to be larger and round in shape. Actually pretty easy.
2) The rear upper control arm frame side holes must be drilled out. The drivers side is easy to drill out. The passenger side is a PITA. The exhaust is in the way so you can't fit a drill in there. You must have a long enough drill bit to go through the frame hole and drill from the outside.
3) There are also two options for the rear track bar. It comes down to the axle side track bar bracket. For a 4" lift you are going to want the angled track bar bracket. This will allow you to adjust the pinion angle to the proper position without binding. Also, if you don't install the angled track bar bracket the bolt for the track bar will make contact with the gas tank at full bump. I believe this bracket requires welding, but it is pretty important.
4) To answer your question directly about the rear track bar; You will need both the adjustable track bar, to center the axle after the lift, and the bracket to keep angles close to stock. When you lift a rig without a adjustable track bars and you use the stock track bar it will want to suck the axle over to the passenger side and over to the drivers side in the front.
I don't know if you are planning on running spare tire carrier or not. But you will also need to specify for regular rate rear springs or heavy rate rear springs. Heavy rate springs are for big heavy anchor like tire carriers. Regular spring rate are for no tire carrier and lighter jeep.
I would highly encourage getting it. It wont handle like the stock sway bars, but it is not bad at all.
