this is pretty easy if your good with a welder. the lift gives the diameter of the axel tube plus the thickness of the springs for lift,in other words 5.5 on a jeep. i think it'd currey that sells a longer spring purch that is sapposed to limit axel wrap which is a big prob with these, you have to watch you steering geometry on the front also. other that,it's purches. brake lines, pitman arm, u-bolts, and time. The other prob is solving your shock delima by doing an soa you move your shock mounts 5.5" closer to the mount so you will have to devise a weld on type shock. if you have an older cj it's also a good idea to track down the newer front shock mounts which will give you a 4-5" higher shock mount in the front. it took 2 of us a good weekend to do. and mine was the second one we did. a yj was the first
