I'm thinking about doing a rear coil swap on my XJ, But i have some concerns,
Here are some specs to help you,
My Xj is an 88' 4.0 aw4 and 231 W/AA sye
About 7" lift in the front with long arm setup and a RC D44, full width.
Rear end is some what needing improvement, I bought rear springs from Rock Krawler and the guy told me that they were 5.5" lift so i bought a shackle to go with them, and for about the first 3 weeks it sat at about 7" and then as the springs got broken in they sagged to maybe 4.5" and they are really stiff, They don't flex for nothing. So i thought that i would go to coils since i have a set of front coils from my xj sitting around,
My question is this, I like the idea of a track bar so as i'm thinking about how to do this i'm going to use a track bar in my design, but what i wanted to run is two long lower arms and one short upper that connected to one of the longer lowers. I have heard that in converting to Rear coils that Xj's can become very unstable. I have heard that if you are going down a steep grade and had to stop for some reason on that grade that rear suspension can "unload" and cause a very hairy problem, My xj is a trail only rig it never sees any highway or city streets im really only worried about off road stability, can some one tell me if i need to worry about it or not really. I guess that my other option would be to go with some big offroad leafs or alcn leafs but they are pricy and i'm not sure they would flex as well as a coil setup would.
any help on this subject would be great, i know there is a few of you out there that have done it, i would also like to see some pics of how they are setup i know a lot of you guys go for the trianglulated 4 link design and i'm curious as to how you run your links.
Thanks for any help and guidence that you can give.
