Ive walked over some off camber spots in my XJ on 10" of lift that some ZJ's on 6" almost flopped on. IMHO the leaves out back really add to the suspension's predictability. Hopefully Nate chimes in here soon, as he's a ZJ owner who feels the same IIRC.
Don't know what trails you are running but this is Bass Ackwards from what I have seen..XJs with soft rear springs...Stable....XJs with stiff rear springs....Very unstable.ArcticXJ said:I wouldnt bother.

The TJ guys that have problems are mostly the guys that don't run swaybars on the front...They seem to think that unhooking the sway bar in the front and leaving the one in back is good....Talk to the guys running an Anti-Rock and see what they say..
If the front of your rig....Don't matter what it is....Is too much softer then the front when you go down an off camber hill the downhill front spring tends to compress and unload the uphill side...If you have way stiffer springs in the rear they won't compress the opposite way and you get a rear end that wants to pass you going down the hill....If you have a soft rear end then it will compress oposite the front and keep wheels on the ground....Hence keeping the body more level and your COG more where it should be.
I for one think if you had coils on the back and kept your suspension as balanced as possable you would find that it works much better on the trails then stiff rear leafs...
The idea that the leafs make it more stable just isn't true.
I had a set of very very stiff Big off road springs(Sorry John John) on my rig and it was sooo unstable...I took them off and went with a set of homebuilt 11 leaf packs on that were really really soft and the stability was ten times what it was with the Big 8s on.Goatman said:Front coil/rear leaf rigs with real stiff leaf springs can lean more than a balanced rig, but they don't sway and are predictable. I know guys with four coil rigs that are scary to drive very fast because they are so unstable. A front coil rear leaf suspension has many positive attributes, especially if the spring rates are balanced.

I agree that springs that fully unload like coils with no sway bars or Coilovers can lead to a very unstable rig but You have to have a balance too. If you front springs are too soft and your rear ones are too stiff you will have an instabiliy problem...I have lived it I know. At the same time I have a good friend with a TJ and he used to run with no sway bar on the front and had the same issue...I still think it had to do alot with the fact that he was running the stock sway bar on the rear and nothing on the front.
Once he put an anti-rock bar on the front though it made all the difference. Now his rig is as stable as my old YJ was and it was the most stable rig I have owned.
I don't disagree that you can't make a balanced rig out of leafs and coils but I think it is very important to have it balanced well.
