the modification you speak of is called a "spring over axle" lift

simply as it implies puting the spring over the axle instead of under it.

i dont know a lot about this since i'm an XJ man but i know it gives you a lot more lift than it looks like and i think axle wrap may be a problem.

there are a lot of threads on spring over axle lifts (SOA) and if you do a search or look in the archives you will be able to read up a lot on this subject.

unless someone that actually knows something replies to this before hand <img src="/forums/images/graemlins/rolleyes.gif" alt="" />
