All lift kits I've seen have the option of a sway bar drop, I'd imagine it would help with bump steer and body roll an all that.

 

Ok fellas,, thanks for taking the time to reply... I'm pretty sure the bronco bar will fit. I'm pretty sure the drop brackets are needed for the 4" lift, I guess the only way to really know for sure would be to put it up on a frame lift and see how far the fronts fall out with no drop bracket, then a 2 inch drop bracket and then no sway bar at all.

Seems like allot of trouble so I wonder if it's even worth it. Maybe just remove the whole thing and just go with the rear only. I guess it just might be a little squirrely at highway speeds in turns/ evasive maneuvers.

 

I don't remember who it was or if it was even on this forum but they said they don't have sways and it really isn't that bad. The springs that come with lift kits for these trucks are so rough that I don't think you would get much flex either way.

 

The sway bar has no effect on bumpsteer.

Look at the angle of the sway bar on a stock truck, relative to the end links - it should be close to 90°. You want it to be CLOSE to that angle after the lift. If it droops too far, it can cause the suspension to ride rough.
