You have a lot of choices to make in the mild lift. Each has it's pro's and con's. A lift "kit" is now avalable for the Jeepster Commando from Dead Goat Motor Sports (
http://www.deadgoat.net), although I have never seen in installed. I found the lift on day while searching the net.
You could always go with longer shackles to lift the rear. Iv'e been told this can get a bit unstable once you go over 1 1/2" high. Early model CJ5 shackles measure just a hare short of the stock Jeepster shackle leingth, so a lifted CJ5 shackle will do the trik. Remember though, to get a 1" lift from a shackle lift you actualy need 2" of extra shackle. (actual ride height is half of the lift of the shackle). Make sure you get the two piece bolt-to-gether type shackles for the rear unless you find a vehicle with the same spring width. Check out:

Another option is to lift the body a bit with new body mounts. Some on this board have posted great ideas on making your own body mounts for a custom size lift.
As far as new shocks go, just measure the leingth of your current shocks at full travel, add in your lift and order new shocks that match that travel leingth. You will have to ask some questions at the parts counter because every parts guy today want's to know your model and year to match up the part! Just tell him it's a custom application and your going to need to measure the shocks! Some of the shock manufactuers even offer a lift guide that guages the lift on your rig and offers the new shock part number to fit your lift.
In my opinion, the best solution by far is to have your existing leaf springs worked over by a spring shop or replace them with new custom springs from National Spring or Alcan. Not the cheapest route, but in the end, those old springs should be replaced anyway.
Hope this helps!
