If you aren’t going to utilize it off road don’t lift it. Jeeps have enough rolling problems as it is.
Very light off-road is the most I have in mind. Good enough for light go pro fodder.
2 inches isn’t much. I would never, ever go over that in a jeep.
Jeeps springs in old CJs tend to sag on the driver’s rear or at least the majority I’ve seen and the ones I had.
The project CJ7 will not be lifted. I like it just the way it is in that regard.
