I installed their 3" premium plus in 2012. I've slowly been phasing out their stuff I wasn't happy with, and their customer service left a bad taste with me.
I had all 4 of the 3/4" heims go bad in under a year and less than 5K miles (front and rear trackbar and front upper frame joints). I chalked it up to New England winters but the replacements I put in (bought somewhere else) have had no issues.
I bent their front trackbar at the clearance bend. I bent the rear trackbar where the tube is welded to the all-thread. I've since swapped the front. Still run the rear, though probably not for much longer.
The springs rode rough on a 2 door and gave me 1.5" more lift that I really wanted. I had ridden in other jeeps that rode a lot smoother with the same shocks and different springs. The free length wasn't anything impressive, they would unseat with pretty normal shock/bumpstop combos in the rear. The front would unload like crazy on steep clmibs but, again, light 2 door. I've since swapped those as well.
2007 2dr X, 6sp, 35's on D44's, 2" lift, cage, hydro, etc.
