I would recommend going either OME or Ironman. You could piece something together for around $700-$800
Something like these:
KJ Ironman 1.5" spring lift kit HD - Econo Lift Kits for the KJ - Liberty 2002-2007 (KJ)
or this
OME 1.50" lift kit KJ
They will have you sitting over the 1.5" shown and you can toss in some top plates/clevis spacer etc to get it up even more.
Or if you wanted to throw a bit more money in to it there is also the Tommudd Eocono lift with A-arms and everything combined.
Those would be the way to go if you are on a budget as opposed to a spacer lift.
You could piece them together yourself instead of buying it all at once as a kit as well. get 2 shocks here. 2 there, springs another time and so forth to spread the cost out. Not sure if money is an issue or not.
