Just to clarify, from all the discussions on another F-150 forum, 3-inch and higher will cause premature wear on the upper control arms, lower ball joints and possibly the tie rod ends. With a 2.5-inch it generally is okay to go with stock components.
Heh heh! I'm not into Apple products but since this is the only F-150 forum that I visit now I guess I better get more involved. Also nice knowing that this forum is pretty laid back, and I haven't run into any assholes so far.
