any thoughts, pros/cons?

Got them on mine, but have yet to do anything with the rig. A friend of mine runs them up front and swears by them. Plenty of write-ups crushing them on Pirate.

From what I’ve heard it’s not worth putting them on a XJ, It will give you more articulation in the back but the problems I have heard is once they start to unload you basically don’t have any weight on the tires giving you the same scenario as if you didn’t have them on at all and the tire was in the air.

i remember hearing bad things about them but cant remember why. I was spoiled with coils on the TJ but now with the YJ its like a whole new learning experience
