Reviving this thread since I've been on them for a few months now and been able to test the set up over some different conditions. First things first, I don't know what rear bumper they had in mind for these as the intended weight, but my 4x4 labs with a spare + hi lift is apparently too heavy. I have a reverse rake pretty much permanently and am installing either 1" or 1.5" spacers next spring. However, that being said the rig definitely articulates better than the OME set up it replaced and despite the sag I never bottomed out in some whoops, even though the FJC I was with did a few times. They suit the weight of the vehicle well for on road manners without being stiff or jarring on square edge bumps. No complaints from a 5400 mile road trip we knocked out in July, or when I towed a 4k lb van from WA to CO. I could've taken a little more lift on the Rubicon, but I think I'll upsize the tires to accomplish that. With 2.5* OME bushings in the control arms and 3* caster bushings in the knuckles, it drives nice and straight with no vibrations either. Would I buy it again? Yes, but only if I already had the Icon shocks in the first place, since the off the shelf 2.0s do not work with the slinky springs. Had I had the option, or if i was starting from scratch, I would have gone slinky instead and gotten a little higher spring rate for the rear.
