Antirock and shocks

I installed a antirock torsion bar on the front of my TJ last year. Since then I have been trying to eliminate the excessive body roll I feel on and off road.

I've read many post where people rave about the antirock system. Honestly the way I'm set up I wouldn't buy it again. It leads me to believe I have my system set up poorly.

To start with I have the currie 4" lift with a antirock torsion bar on the front and stock torsion bar on the rear. Everything was a complete kit from currie with the exception of the bilstien shocks.

At this point Im thinking my choice of shocks per application may be my deficiency. Can anyone shed some light on the best shock / antirock combination? Or am I off base on my assumption about the combination shock and antirock?

I have the 4" Currie kit and AntiRock with Bilstein 5100 series shocks....

What hole/position do you have your AntiRock setup in ?
Have you contacted Currie ?

Jeeps in Az I'm in Mn, long story..

We set the hole position originally second hoe from the rear. Then moved it to second hole from he front. If memory serves me correctly.

Bar is set horizontal.

I have talked with Currie they assured me springs were tested before shipping. They did exchange my torsion bar for a heavier one. It all helped but I would hate to have to do a quick Lange change at highway speeds.

I removed my anti rock because of the effects of the body roll on my TJ . The body roll itself was not my problem . I think my problem is the effects body lean has on a lifted TJ on short arms in their stock mounting location . It seems to make it steer like a skateboard , it leans , it effects steering and an anti rock allows even more body roll. that is just to many things effecting the tracking when going down the highway , constant steering correction it seems . It looks like more work to fix correctly than the Jeep is worth to me

My TJ does not have excessive or, really, even noticeable body roll with my Antirock set to its most rearward/loosest setting. That's with Currie's short control arms mounted into the stock mounting locations which is a very common setup.

If there is excessive body roll, something else is going on which isn't related to the control arms or Antirock, even when it is set to its loosest position like mine is set to. Possibly/probably the shock absorbers, underinflated tires, etc.

Constant steering connection is usually nothing more than an improper toe-in or caster angle adjustment.

The only other thing I can think of would be if the rear antiswaybar was removed or one of its links was broken which would completely disable the rear antiswaybar which will increase the amount of body roll.

My TJ is running short Currie control arms, an Antirock set to its loosest setting, 35" tires inflated to 25-26 psi, OME Nitrocharger shocks, a 4" Currie suspension with a 1" body lift, properly aligned, and it handles like it is on rails... even on my very twisty local mountain roads.

Most of the crew I wheel with in Moab run the anti-rock. Their vehicles all have more body roll than I like and am comfortable with on the road. Most of their vehicles are not daily drivers like mine. Off road I disconnect for articulation. There have been a couple of pucker moments off road being disconnected rather than running an anti-rock, but like I said my rig is mostly DD with some off roading and theirs are mostly off road with some daily driving. That being said I will not be putting one on my DD Jeep. Now if I had a dedicated off road Jeep I would be running one. Is your Jeep a DD or a off road vehicle? That makes a big difference.

Exactly what shocks are being run on the TJ's with the Antirock where you don't like the added roll? That would only happen with soft shocks, it doesn't happen with good quality shocks like OME, Bilstein, etc.. As said above, both of my TJs with Antirocks, even set on their loosest setting) handle extremely well with good shocks. The only TJs I have driven where that was a problem was with soft shocks. You only need to run a good quality shock to run an Antirock and retain good handling.

^^^ Agreed, I wasn't happy with mine until I installed a good high quality set of gas shocks, Really makes a difference.

I had bilistein shocks installed. You may be onto something when you mentioned the rear sway bar. When I get back to Az first thing I will do is give it a close inspection..

I can tell you the front of my jeep is sitting higher ( level wise ) then it was before the lift was installed. When I fill the back of the jeep with a couple hundred pounds it seems to reduce the roll considerably.

Thanks for your help. Anymore advice or ideas are appreciated.

running fox 2.0's and the AR with BDS springs 3"/2" and have little to no body roll on the loosest setting

i'm with Jerry on this one, a set of quality shocks and a properly setup and maintained suspension should give little to no added body roll when using the AR, even in the loosest setting

There is a very good thread on WF about the theory and physics of the AntiRock. Might be helpful to explain how and why it works to the nonbelievers.

I have bilstein 5100s ans my AR on the loosest setting and have little to no body roll. I was wondering when I had it installed how much of a difference it would make and I honestly didn't notice one.

You need to ride in a rig that has been set up correctly. I build them fairly often with A/R's front and rear and never get a complaint that the body roll is excessive or even noticeable and these are daily driven rigs. One in particular lives at the summit on the 74 between Lake Elsinore and San Juan Capistrano.

Once your wheeling expertise increases to the point where performance and traction matter, you won't be disconnecting any more.

The body roll is not the fault of the AR, it's a flaw that shows up when the rest of the rig is not set up well.

You guys are restoring my faith in antirock! I'm sure it's somehow in my setup. Im not sure yet but when I get it figured out I will let you know. If I don't get it figured out I'll let you know :0).

I have Bilstein shocks on my LJ with the Anti Rock on the lowest setting and it doesn't lean too much. I can keep up with traffic on mountain roads without problems. I would also feel safe making a very quick lane change with it.

I love my antirock and wished I would have listened to people who told me not to go with disconnects. Much more secure feeling on side hills and much more capable. I will say outboarding the rear shocks will give you a more planted feel. If you want the feel of a stock sway bar and want to enjoy the benefits of an A/R, you might want to look at the ORO Sway-loc. I've got a friend that runs one and he swears by it.

This thread is pretty educational...

Today I had time to look over my 2004 tj. And the 4" curry lift with front antirock torsion bar. Anti rock torsion bar is set second hole from the front. I have 5100 bilistein shocks. Rear torsion ar and links are in good shape.everything appears to be installed as per design. I have 33" procomp tires. They have two ply sidewalks. I increased air pressure to 45 psi from 35 psi. This only seemed to give me a much firmer ride.

The jeep still has excessive body roll. I'm pretty nervous about highway speeds and having to make a fast maunver. I feel I would loose control of the Vehical.

I'm in the Phoenix area. Any advice who I can have inspect the lift?

My advice would be to post up a picture of your track bars. If there was not a bracket to move your bar back to original position you will have bad body roll.

I reread this tread. I realized I misunderstood Dougzin comment. I thought he was referring to the Antirock connecting bars to the linkage. I'm assuming at this point Doug your referring to the bar attached behind the rear axel. How can I verify its properly set?

Doug,

What in the world are you talking about? The OP should have the Currie 9120 track bar, which uses the factory mounting points. He doesn't need, nor want, any type of extra bracket. The rear Currie track bar setup uses a bracket at the axle side, which slightly raises the mounting point and, thus, roll center. His issues are not stemming from the track bars at all.

I also have the 4" Currie lift with AR and Bilstein 5100s. I was running 33" Duratracs and have moved up to 35" MT/RKs. I think part of your problem is over inflated tires. I ran my 33s at 28psi and my 35s at 26psi. Also my TJ is not a DD but it sees more road miles than trail so I run the AR on it's tightest setting most of the time. Before an offroad trip I change to the most flexible setting. It takes 5 min with 3/4 and 5/8 wrenches.

You went the wrong way with tire pressure, you are way way too high.....drop down to about 28...

45 psi? Even 35 psi was excessive for your 33x12.50 tires, they should be more like 26-28 psi. Generally speaking, the bigger the tire the lower the air pressure it needs.

I'm trying anything, playing with air pressure seemed like a cheap test. Generally I run between 30 or 35 psi. Will bring the pressure back down and play with the lower pressures as recommended.

I feel the roll is in caused by something in the rear of the jeep. Like I mentioned when I have a 300 plus pounds in the back it rides much better. When driving the rear of the jeep is where I feel the instability.

As they mentioned tho, 30-35 is still a bit high.

I have been in a few decently set up TJs with AntiRock and spent lots of time reading/drooling over since I cant afford it right now. My Tj was my daily driver for a long time while on 35s. For a long time I hated the steering/feel. I spent a lot of time going over all the bolts making sure they are tight(track bars, crown nuts on the tie rod ends etc). Found one or two thats holes were rounded. I also replaced the steering stab. and the tie rod ends, went with heavy duty track bar/tire rod.

Now I did all this and Im running a non desirable lift(RC 6" long arm, with RCs 2.2 shocks) and when I was done addressing all the issues up front I was able to drive the Jeep on the road full time with the front sway bar disco'd. I actually broke one of the links and just never replaced it. I experienced less wandering around the road or body roll then some of the guys I wheel with who had them connected.

I know this was a long post that isnt what your looking for but my point is, with time spent ensuring everything else is right you could get away with no sway bar, so adding what many consider to be the best "sway bar" set up should not be causing your trouble.
