I have a new problem I want your input on. My ZJ works very well on and off the trail and rides amazing. The problem arose right after installing the long arms and new front RE coils up front. On the trail, when off camber, it unloads big time. It feels like it's going to roll over at points where even taller Jeeps don't. Add in the fact that the engine torque pulls the Jeep to the side most of the trails lean, and it makes it very spooky. This is at a tiny lift of about 3-3.5" I have wheeled Jeeps for 9 years and this has not been an issue before.
I thought of a couple possible solutions:
-install Addco rear sway bar
-install a Swaylock or similar front sway bar (CSL sells them for a ZJ)

Radius arm style long arms paired with softish coils can do this without some kind of body sway control. Considering the rear is coil-sprung too and the rear swaybar isn't exactly too thick (if you even have it anymore), it will lean to the side fairly easily. I'm suspecting you're running radius arm style long arms instead of true 3-link? The bad habit on radius arms is it's lack of sway and brake dive/ front unload control. As you mentioned, an adjustable sway bar like swaylock or Currie anti-rock might be a good idea for you.
When I swapped from short arms to radius arm style long arms on my XJ keeping the lift height the same, the difference in body sway wasn't that big, but on the XJs the rear leafs help on preventing body sway a bit better than coil springs + stock 4-link rear. There was a clear difference in brake dive/ front unloading on steep inclines though, and there's really not much you can do to it with radius arms (stiffer shocks help a bit, but it is not the solution either).
