I recently installed a 3" OME kit that I purchased at DPG, ZJ V8 front coils and the JC2A rear leaf packs with an MJ shackle. I have the ARB in front (no winch) and although I don't have a heavy duty rear bumper, I do have a fair amount of weight in tools and rack that add to the weight. I can tell you that it does ride a heck of a lot better than my stock suspension did and from what I have been able to test it definately flexes a lot nicer too. It was a pretty easy kit to install, but the kit I had did not come with bushings (although it did come with JKS Quicker Discos) so make sure you look into that. The biggest suggestion I can make is look into the longer travel shocks, I got the ones appropriate for the lift I got, and after the shackles I definately have more flex than shock travel. That is my $.02
