Now Im thinking about the rear. Is is worth it?
The stock doesn't seem large enough to do much, but now, I guessing its going to get more of a work out.
Or will it be fine?

I have another question about a drive shaft idea i have, Im sure its been brought up before just can't find anything about it.
I think i will just start another thread on it

Longer links may help. I still use my stock rear with the Antirock up front. Seems to work fine.

Rear antirock needs welding. Something to consider if you dont weld.

As much as I like and consistently recommend Currie's Antirock, few TJs need one in the rear. At least in my opinion, a rear Antirock is meant for those with frame-up builds with no previously existing antiswaybar or those whose rear ends have been so modified that the OE antiswaybar can no longer be used. When present and usable, the OE rear antiswaybar actually works very well as is.

I got a chance to drive the jeep around town a little.
It's different feeling but not bad at all, I like it.

It feels like my big block roadrunner, with the left front coming up when shifting gears. (not power wise, lol)

For me, I can leave it hooked up.
And not have to fight with trying to hook up the disconnects after off road ing

The Antirock works with the rear swaybar to give you more stability offroad vs being totally disconnected up front. Plus, it's nice not having to disconnect, and reconnect after offroading.

Wow I had no idea that the anti rock was setup like that. I thought it just ran in the same location as the stock one did. I've been wanting to buy one for awhile but being on a college students budget money is tight especially while restoring a '67 Camaro that gets priority over the Jeep.

What exactly is the antirock supposed to do? I see its very popular but have no idea what its purpose is.

I posted this on another forum so he's a little copy/paste action:


You've got to able to apply some common physics and geometry to this scenario in order to understand it. Here goes my little explanation that I came up with--when it comes to a link suspension, you've got several items that need to take place--support, constraint, and a relationship with the frame. The first item is support--the coil springs support the frame and that's all they do. They determine how high up the frame sits from the axles. Next is the constraining/locating components--those are the control arms and track bar (if applicable). Without those, the axle wouldn't have anything defining it's orientation relative to the frame, nor would it have anything keeping it from rolling around itself. The constraining members define how the frame behaves during moments of weight transfer (anti-squat, anti-dive, roll center and axis, etc). The last component is the relationship with the frame.

Think about this situation--your front axle is articulated one way (let's say driver side drooped) and the rear axle is articulated the opposite way. In a scenario with no sway bars, your frame and axles aren't 'communicating', thus the sloppy, rolly-polly feeling on road. It's not a stable condition regardless of the terrain. With coil springs, you just can't have stiff enough springs to take care of the weight transfers on their own--enter the sway bar. A sway bar flexes in a torsional manner and any time it's twisted/loaded, it wants to return to its neutral state. This force is essentially attempting to keep the frame neutral (LEVEL) while the axles are at an angle...you can view that force as a 'helper' to the springs and shocks as well. The stock front sway bar is too stiff to allow much deflection, hence why it needs to be disconnected. The rear sway bar is much more flexible, hence why it doesn't need to be disconnected.

Enter the AntiRock--it's a torsion bar, just like the stock sway bar. But it is more flexible and works in a more efficient manner than the stocker. Take another scenario--stock rear sway bar + no front sway bar (disconnected). You've now got a sway bar influencing the relationship between the rear axle and frame but nothing going on up front. That's an unbalanced situation and generally, the frame follows the rear axle....ie, if the driver's side is drooped, the frame dips that direction. That's because you don't have a front sway bar evening out the forces acting on the frame. Another scenario--AR up front, stock rear sway bar--now you've got a somewhat equal/opposite relationship and the frame stays fairly level even when the axles are articulated. Additionally, you've got the assistance of the torsional forces helping to keep you upright in off-camber situations.

I've ran every scenario--stock on both ends, stock rear/disconnected front, AR front/stock rear, and now I run AR's on both ends. I can tell you that without a doubt, AR's on both ends is fantastic on and off the road. The rig has never felt so connected. Even with the AR up front and stock rear sway bar (which worked very well), the rear always felt a bit 'separated' from the front, mainly when on the road. With both, it's unbelievably great due to the rear AR's stiffer-than-stock rate. As for the body roll, it's a non-issue. With a good suspension setup--quality control arm joints, gas charged shocks, good springs--the ride is better than the overly-stiff front sway bar and it handles great. With AR's on both ends, body roll is nearly nonexistent and the added confidence offroad is awesome. One recommendation--get over the Jeep world's obsession with the term and idea of "FLEX!!!!". Guess what? Your Jeep will flex as much as the shock travel will allow, regardless of arm length and what sway bar you're using. It's up to you to use components that can put up with that travel without crying for help. Proper sway bars will help you in the traction and stability departments--that's what REALLY matters.

-------------------------------------------------------------------

As for the rear AR, I didn't expect much of a difference. I'll leave it at this--the difference is worth the cost on and off the road. AR's or any comparable torsion bars on both ends are key ingredients to the best driving rigs out there. Jerry, go throw one on yours and report back with how you feel after driving to and wheeling at JV.

Wow, I'm sold. I need to get one. My jeep is my DD, is it still a good idea to use an anti-rock?

Yes. I believe Imped's Jeep is his DD (well, when it's not in pieces in the garage), as is mine. It's definitely one of my favorite purchases.

I DD mine when it's not down for months at a time. I wouldn't have it any other way.....the stock front sway bar sucks.

I mention that as a nice byproduct pretty frequently. It makes perfect sense if you think about it. The stock sway bar is very stiff, hence it needs to be disconnected in order to let the axle articulate freely. The same thing applies in a much smaller scale when driving down the road and a less-inhibitive sway bar allows more forces to be taken by the springs and shocks instead of sent to you.

Only thing I can tell is maybe some grease on the plastic pucks and the bar?
Someone that has had is a few years might could say more than me.
I would like to know about that too

It does require feeding. Lots of rocks. Mine is getting feed in June at Moab.

Dang. I sure wish I had some rocks around here.

I missed a trip to land between the lakes a month ago.
