These were a little rough in the back. The ICONS are a little rough on the highway too, they have since settled in. They have broken in now and seem OK. If I was to do it all again, I would go Bilstein. ICONs are made for off-road, I drive on highway 99% of the time.
Fox maybe OK in the front, but I have never run them on a 150. The shocks above were 2.5" shafts. Too much unless you off-road all the time.
