Mine really doesnt have that much body roll for a truck, but if your going for good handling or a street truck then I could see wanting one. I cant really tell much of a differents with mine off but maby mine was worn out, flexing, offroad, and 10 years of service have probably weakened it.
I bet you could go to a local junkyard and get one cheap. Nothing has really changed so I would think any sway bar off a ranger with a 8.8 would fit. I think all sport models should come with sway bars. I mean its a SPORT model so it should have some sportiness to it other then the looks.
