The best kit by far within the 2-2 1/2" range is the Old Man Emu kit. This kit is about 2 1/2" tall. The ride is the smoothest I've ever experienced in a YJ and the flex is outstanding too. This kit is a little more than most, but well worth it. I had an OME kit on a previous YJ (the only reason I don't with this Jeep is I wanted more lift than the OME kit gives). Definitely a "2" thumbs up kit.
