I'm looking to buy a suspension lift for my 2003 f-150 and am looking at the 4in. pro comp and the 6in. fabtech but am not sure which one to get. Does anyone have any opionions on any of these? I want a lift thats going to last..thanks  

I would definitely go for the fabtech lift.  Procomp is okay but I've had better luck with fabtech stuff lasting longer.  Good luck!  

Thanks for the info. I was leanin towards getting the fabtech. I think thats what I am going to go with.
