I have the skyjacker lift on my '02 KJ,had installed since april of '04 and have put 12.000 miles on it.It was the only spring lift at the time and I also did not want spacers.It rides a little stiffer that stock but I like the ride(used to big trucks),and the upper ball joints can hit the spring at full droop,but I believe most others lifts will to with the same height.Frankinlift has a bumpstop to protect the upper ball joint I think but cost a little more.I've never had a problem yet with it and like it very much.Here is the front struts and springs on my Libby.
