My truck came w/o one, so I went to the Ford dealer and bought the OEM one and also had to get the bracket and hardware to mount it. I Probably could have gone to NAPA or somewhere similar and got pretty much the same thing for a lot less. Unless you are having shimmy problems or are running huge tires you shouldn't need to spend a lot and get some nice dual setup...so if I was you I would price the one from the dealer then compare to an aftermarket replacement from the parts store and just go with your gut. A steering stablizer isn't that big of a deal and I've seen the OEM Ford ones leaking as low as 40,000 miles so unless you want to spend $$ on a real nice one just get a cheapo IMO.
