Do a search on "lifts" for details - but the short answer to your question is "Yes."
Don't let 'lift' scare you away. As you said your Jeep is sagged so any coils are going to 'lift' it. Go with OME coils and Bilstein shocks; your ride will be WAY better than factory. I didn't know if i could believe the claims before I did mine but it's for real. I built mine for highway and off-roading and it performs brilliantly in both venues.
Figure about $750 US for a complete kit before duties and all the other hurdles you have to jump when ordering from the States.
