A 2.5" Teraflex spring lift is a good one. The differences are, one has shock extensions where you can reuse your factory shocks, one has shocks with the kit and one is a kit that needs shocks but you supply your own. Then the same set of products is repeated for the 4 door, so in effect, 6 options for the spring lift.
So it depends on what your budget is and if you want shocks tuned for highway driving or off road use.
I went with the Teraflex Part# 1351002 kit (I have a 2 Dr). It' required me to supply the shocks and I went with Bilstein 5100's. They are a bit stiffer than the factory shocks for highway use but really nice off road.
If you have a 2 Dr and want to reuse the factory shocks, use kit# 1352002 and if you want the kit and their shocks, it's Part# 1251002.
PM Kolak, he is a Teraflex dealer and usually has very good pricing.
The much more expensive kits have control arms, etc, which you most likely won't need for what you indicated your use will be.
