That's a very valid concern. Most aftermarket adjustable track bars will get into the diff cover and other suspension components in the front at least. I'll do a little looking around again but I think that there are only two adjustable track bars that don't cause problems that I know of. I also think that the Currie track bar needs to be modified (shortened) to fit. Not a huge issue, but there it is.
You can run a 31" tire on a stock TJ, with stock springs and wheels with the correct backspacing. With what you are talking about, my guess is that you will get around an 1-1/4" to an 1-1/2" with the H&R's. Just order up the springs for the six cylinder model and go with the flow.
Tummy tucks are never simple. Lots of moving parts there that need to be coordinated to work correctly. For FS roads, mild trails and snow, just put the H&R's on with your choice of premium shock, wheels with 4" of backspacing and the tires of your choice. I wouldn't even do the locker, to tell you the truth. You can go a long ways in the back woods without one. No body lift either. Set it up that way and drive it for awhile. If there is a performance problem address that specific problem then. I think that you'll be very surprised at what a basically stock TJ will do.
Yup, a BL is only needed if you're doing a tummy tuck or you're running your tires into the fenders and want to address the issue that way. There's better ways to accomplish the same thing though. You don't need a cable shifter for a body lift, you can relocate the transfer case shifter with a bracket to accomplish the same thing. The cable shifter just works mo' better.
Check out tire rack dot com for the hr springs. They had the best prices when i was checking. I ended up with OME springs, but was leaning heavily on the hr for a while.
I got my H&R's from Tire Rack. Best price going at the time.
