I have 2 inch daystar lift with stock struts and shocks. had it installed when my KJ was 18 months and 24k miles on it. Could only get alignment close at first, had it done again 2 months later from a better alignment guy and am very happy with it now. most have found that you need to let it settle after the lift is installed.
Like tommudd says, if you might need new struts, now is the time to do it. Shocks are easy to change anytime.
