I have a rubberdown customs 2" lift on mine and the fronts bound at full droop. It was no big deal but I made some custom limit straps to prevent that from happening.
I am happy with the rubberdown customs 2" lift, rides decent running factory fox shocks and turned preload up a tiny bit for a little more lift it currently sits 14.5" in front and 14" in rear on factory bighorns after settling with about 1/4 to a 1/2 more preload over factory specs.
It rides nearly factory, just a little stiffer but you can always back off the springs a hair. I found that sitting at factory 12.5" I had hardly any preload on the shocks and the thing handled amazing so it was like a win win situation lift when you want and great handling when you want it all with adjusting preload.
