Teraflex 3in install write up?
Don't forget before and after photos.
Very cool. When are you installing it? What wheels and tires are you going with?
It is a nice kit, you will be happy. Between the awesome Project-JK write up and the TF docs you will have all you need. I used the lengths from the piece of paper that came with the flex arms and mine rides real good. The only change i am making is to go with front adjustable track bar. I think you could get by without it but I want mine to be setup as correct as possible. The only thing I had to fight (other than myself) in the install was the rear track bar bracket. The bolt hole to the old track bar mounting bracket did not want to line up but I bolted to the axle and control arm mounting bucket then "persuaded" it to align with a floor jack. I had three floor jacks to do the install and they came in very handy. Good luck. 
I was hoping to be able to do the lift with only one floor jack and jack stands--cause that's all I got. Guess I could call in some favors for some floor jacks.

I ended up doing all of the rest of my lift (better than 95% of it) with a tiny little 2-1/4 ton fleamarket special 15" reach floor jack.
It SuuuUUUCKED, but it worked.
jack a little, adjust stands, jack a little, add blocks, adjust stands, jack a little more, add blocks, adjust stands, etc, etc, etc, and my crappy little jack is still going strong. My "good" floor jack is stuffed under the workbench, once i'm not completely pissed off at it anymore, i'll drag it out and see if i can fix the seals.

So yes, it can be done, but it adds a lot of jacking/blocking/stand adjustment time.
There are places where having 2 jacks is going to be indispensable. When you are trying to bolt up the new CA's the length will not fit if your axle is still at the same place as the stock units. The easiest thing to do is to have the pumpkin supported with one jack and then put another at the pinion to move the axle into proper alignment. It is cake like this. It could be done other ways but would be tougher.



I was hoping the 4" write-up would be pretty similar!! Hopefully I'll be getting started this weekend.
gotta see some of those teraflex pictures!!!!!!!!!!!
