You won't even notice the difference of the rear sway. Even the front I didn't notice that much, although I did a little and keep it connected. The rear though is WAY to small for the size of the jeep, especially if you're running much of a lift. You would be better off going with wheels with more offset, or carry less weight.
As long as you have the same amount of anti-sway stiffness, it should handle the same whether the stiffness is in the front or the rear. For a front engine, rear wheel drive car, you want most (if not all) of the stiffness in the front. Sway bars in the back tend to lift the inside rear wheel causing them to slip (spin under power).
Its also not true that you want all your stiffness up front, that creates understeer; depending on the rest of the suspension. Not to mention having a straight axle, vs independent, will play more of an influence on removing or adding anti-sway stiffness to either end.
Don't forget your 4.5" leafs are much stiffer so that helps control sway too. Also a good set of shocks.

I took my rear swaybar off after about of year of a 3inch lift with it on.
Didn't even notice it was gone till I went on an offramp doing like 45mph. Was a bit sketchy. BUT, when I later replaced the front sway bar links with proper sized ones, it feels better than it ever did stock. Not to mention do that offramp at 45mph now hah
Ditch the rear swaybar. Get new swaybar links for the front for your lift size. Disconnect or not.

Ok how about towing the jeep with a tow bar. I was thinking about throwing all my gear in the jeep and towing it behind my Yukon. I have heard it will sway pretty bad. Anyone done it ? With? With out?

from my limited research in oem front sway bars for xj/zj was that there were several different size diam. ranging from 23-28mm. the only way that you're gonna find out what you have is to measure & go from there. i need to do this to replace my sway bushings. i'm sure a quick search (or maybe dukie?) would reveal which years/models/trim packages came w/ what. but it would make sense that tow packages, upper trim levels, & larger engines would all incorporate thicker front sway bars.

yea..that would make sense, but it seems completely random. For reference sakes, the v8 grand cherokee and my 1995 sport sway bars were 1" O.D., and were shaped differently






An anti-sway bar (ASB) increases effective spring rate, but only when one side of the chassis is loaded more than the opposing side. The increased spring rate is intended to come into effect primarily in corners, and it affects only one side. The increased spring rate originates from the torsional twisting of the transverse part of the ASB, caused when one end link is in a different plane than the other. Hit an undulation in the road and both of the sway bar's end links are pushed upward the same amount and the torsional effect does not occur. Enter a chicane and the suspension on the outside wheel compresses. This compression pushes the ASB end-link on that side vertically, toward the floor of the chassis. That force is transmitted through the transverse part of the ASB to the end-link on the other side, at the inside wheel. The weight of the XJ on the inside wheel is telling the end-link on that side to stay put. That resistance to vertical movement on the inside wheel versus the upward force from the outside wheel is what twists the transverse part of the ASB. This is what adds effective spring rate to the outside wheel. The additional spring rate reduces compression, which reduces chassis roll. In short, the XJ has rear leaf springs. These have a fairly linear response to loads compared to most coil springs because they are wider and mount across a larger surface area on the chassis. This stability lends itself to a more forgiving suspension with a generally much rougher ride. They also do not "bend" horizontally like large coil springs can. They have less "sway" to begin with. Thus the reason leaves are often preferred by those on a tight budget.

^^ wow long winded post, but correct.
The rear leaf springs and live rear axle setup negate pretty much any need for a sway bar in the rear.
