So I'm seriously thinking about getting the Currie 4" lift; everything i've read about it has been positive. Those of you who have this kit, is there anything i should know or think about before buying? Should i opt for the antirock sway bar? What about rear track bar--adjustable or relocation bracket?

I don't have the kit, but do run Currie CA's and track bar. I can tell you that you won't be disappointed going the Currie route. It is top quality stuff. Since you will need an sye with a 4" lift, adjustable track bars are the only way to go. I would also go with the antirock if you plan on being off road a lot. Savvy Off Road has kits that includes all that: Suspension Kits

A few things that are different between this kit and some others.

FRONT END

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.

REAR END

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.

COIL SPRINGS

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.

ANTI-ROCK

I would highly encourage getting it. It wont handle like the stock sway bars, but it is not bad at all.

What is the difference between Currie, Savvy and Currie/Savvy? Are they one company or two separate companies that teamed up to produce a lift kit?

The main difference I'm aware of are the control arms. Savvy's arms use Currie Johnny Joints but their lengths can be adjusted without unbolting them. That makes it a lot easier to adjust/dial in pinion and caster angles.

Savvy also has specially dialed in and tuned Fox shocks that gives an amazing but still controlled ride. I loved my OME Nitrocharger shocks but they lost a little luster after I had a chance to test drive a TJ with the Savvy-Fox shocks installed.
