I believe I am the only one on the forum with the pro comp dual coilover kit. It is not very cheap. I paid $4,000 for all the parts for this lift. I love the way it looks and I get a lot of complements because of the uniqueness of the dual coilovers. I have not had any issues with mine.
The thing is they do not make this kit for the 2011 Ford. I bought one for a 2005-2007 F-250 and had to have a few things changed like the sway bar setup and the rear spring alignment. Overall I am pleased with it.
My buddy kodybyron on here has a bronze F250 and just had the 8" procomp stage two kit with resi's installed yesterday. We are both running 22x37s with no rubbing in any position.
The Icon is a great kit and sits at about 7"s and rides great. My lift sits at about 9"s.
There will be many opinions on both lifts you will here a lot of people on the forums bash ProComp, but they have been around for many many years and I had their lift kit products on my 2008 and 2011.
Good luck with your decision and it is really all about personal preference. I get people say my truck does not look good, and then others absolutley love it so to each their own.
Hope this helps ya!
I have attached a picture of my White King Ranch and my Buddies Bronze King Ranch with both ProComp lifts.
