I have a 4" pro comp, it's pretty beat and saggy now though, and I have removed both trac bars, but since almost getting run off the road by a pickup truck last fall, I keep the sway bar connected except when wheeling. I know it feels fine on the street without it, but if you ever need to do an emergency maneuver, you will see the need for the sway bar - it ain't pretty. believe me if you choose to.
As for sway bar disconnects, I see no need in spending $80 or whatever they get for those things. Remove your lower nuts, pry off the link with a pry bar, grease the bushing good with antiseize or grease, and put it back on. Find / make / steal from a friend / borrow a pry bar / pry tool with the right bends/support points for ease of pry-off, and the 3/4" wrench, and keep it handy. When I remove the lower end, I zip-tie the links up under the fenders with heavy zip ties. I can do both sides in maybe 3 minutes, max.
Done.
Good luck,
Pete
