QD vs anti rock, vs no sway bar

Ihave a QD front and (come to find out) no rear sway bar, I was wondering if I threw an anti rock in the back what would that do to my (scary) body roll when I'm traversing a trail that has a lot of side lean. I'm assuming it would straighten the body out a little bit, make it a little less likely to tip, or am I thinking that backwards?

My understanding is that the rear anti rock works in conjunction with an anti rock system up front. I would just find a stock rear sway bar from apart out, much cheaper. By the way, I have the anti rock only in the front and love it.

And it was originally built to work alongside the rear stock sway bar. However, running both is supposedly ideal.

First, no coil spring suspension like the TJ's should be running without antiswaybars. Leaf spring vehicles can get away with it since leaf springs are stable in all but up & down directions. Coil springs are unstable in any direction.

So yes, reinstalling the rear antiswaybar would help that in a big way. Soft mushy shocks can contribute to that problem as well.

Front & rear Antirocks are ideal but I'm running a stock rear antiswaybar and an Antirock up front plus OME Nitrocharger shocks and find that combination works extremely well on even scary-steep off-camber trails. It works so well that I'm in no rush to install a rear Antirock.

Well now I,m kind of confused, I thought a rear anti sway bar would make lean (off camber) worse, your saying it would make it better? The travel and articulation on my rear shocks is almost perfect as set up with no sway bar, they travel almost all the way to the wheel well, when fully twisted, But I am planning on adding two jerry cans to my tire holder which should be around 95 lbs total added weight full, I would think maybe then adding the rear sway bar back in would hold the articulation to just the right level and keep me a little more stable in leaning situations, would that be a good assumption?

My front axles actually even with the quick disconnects don't even come close to the wheel well, even with a winch and high lift mounted up front so I might actually lighten those up when I have a chance...

Yeah, in my head I always thought an anti sway bar (tries to) cause the suspension to be linked a little, like if the right tire goes up, it causes the left tire to come up a little bit, which if you we leaning left would only make the lean worse...

Have I been thinking wrong my whole life?

Yes the rear (front too) antiswaybar definitely (!) helps keep the body under significantly better control and will dramatically reduce the Jeep's likelihood of flopping on its side on an extremely off-camber trail. I wouldn't even consider doing the level of trails I enjoy without f/r antiswaybars.

The torsion in the rear swaybar is soft compared to the front and won't hinder articulation. I agree, I have the e-disco up front. My ideal setup would be AR front, stock rear and a good set of shocks.

Having very recently installed an Antirock to replace my front quick disconnects, I agree that having both ends connected makes for a dramatic improvement in handling. I only have 2" of lift, and have absolutely no loss in articulation with the AR on the second loosest setting (even on the middle setting). The difference is that now, compared to being disconnected, the body has something to support it. I have been on some pretty hard leans and the body is nowhere near flopping to the side, where before it did when disconnected. The Jeep is simply more stable and controlled.

In short, yes you have been thinking wrong.

And just to show that even high-end competitive rock crawlers with coil spring suspensions run f/r antiswaybars, check out the below photos. You can see both ends have their antiswaybar connected.

These are of of John Currie's Fireant rig that after a long season of competitive rock crawling events, ended up winning the overall grand ARCA championship the day I shot these photos.
