I tried a search and didnt find much of anything so sorry if this is a double post to someone else. Anyways, I'm pretty close to settling on a price w/ this guy on this 99xj i've been discussing w/ you guys and i am not going to be able to lift it until i pay off the load...only 3g's so it wont take long..but anyways, my 93 xj right now has a 3" lift...what i'm thinking about doing w/ my new one is a 3" w/ a 1" coil spacer and a 1" extended shackle to get a little extra...my main question is one of my buddies told me the shackles will scrape when i go up hills...true, or not? And what is the major benefit in spending an extra couple hundred bux for an actual 4.5" lift as opposed to an extra 70 bux for the 1" extended shackle and coil spacer? Thanks for any info.
