antirock sway bar confusion

Well i just got and installed my Currie antirock sway bar and is all together and works it`s just that I can't figure out exactly how it works compared to the stock sway bar since it's a solid bar that goes through the cross member of the frame. It's driving me crazy. How does it work exactly?

THe same way as the stock unit, just with alot more flex/body roll since its nowhere near as stiff.

Stock sway bar transfers forced laterally; left to right or vice versa. The anti rock transfers those same forces longitudinally; front to rear.

Just got confused since when you disconnect the stock sway bar the axle is independent and the antirock is always connected. Also got confused on the torsion part because one force would be applied to both sides equally, so let's say one tire hits a rock before the other wouldn't the tire that his the rock first cause the other tire to lift to the same height therefore losing traction on one wheel. Or am I just completely over thinking it.

Basically it's a torsion bar that goes across the frame and has built in twisting abilities, so as one side of the vehicle suspension gets compressed it pushes the sway bar link upwards into the anti rock arm and when the arm rotates it pretty much fights what the opposite side wants to do by rotating the steel rod across the frame! So you end up with controlled sway at a softer rate compared to a stock (stiff) sway bar design

thanks for starting the thread CHADWICKY since I have also been driven crazy trying to figure out the effects of the Antirock

near as I can tell, the single torsion bar across the frame twists while under compression and while one side is stuffed the other side "fights" the torque ... i.e. the two arms are NOT parallel to one another when under stress

<maybe?>

Been thinking about getting the anti rock. How much does it affect on road driving?

Pcwolf, that's what id like to know too. I jacked up one side but my jack wasnt big enough to really flex out my jeep to see if one arm would be higher than the other. As for on road driving id have to get back to ya on that as I still have to put on my bumper and winch and haven't driven it yet. Tomorrow probably.

If you want to keep nice on road characteristics.....bypass the Antirock and grab the Oro Swayloc dual rate bar. Its more money, but highly worth it. Its basically 2 swaybars in one. Flip a lever and you can go from stiff on road setting to a soft flex offroad setting.

Give this a read:

As for on the road driving, I have many many on-road miles on my Jeep with the Anti-Rock and I have zero complaints.

Nope, both are anti-sway bars oriented the same way to the frame and both will impart or resist forces in identical fashion. One is just a much smaller bar with longer arms acting against it.

It sorta works the opposite. What we miss is when the body leans over, it is pushing down on the other side.

I've had an Antirock on two different TJs and how it affects your onroad driving is very dependent on your shocks. With soft mushy shocks, your Jeep will be slightly mushier with an Antirock. With good quality shocks like OME Nitrochargers, Bilstein 5100, Rancho R9000xl, Savvy's Fox, etc. it will handle fine if not superbly. My TJ's Antirock is set to its loosest setting yet my TJ handles great... due in part to its OME Nitrocharger shocks.

Also does the anti rock work with the stock bumper. I have seen some other similar products that won't work with a stock bumper and I won't have the money to upgrade the front just yet. Wanted to get the antirock though b4 I head to Rausch sometime in the next couple months. Been on disability for over a year now so money is super tight.

Well I've driven disconnected on the road for about 45 minutes one day because my old sway bar was rubbing a hole in my frame and even then it did seem too bad. I mean you could tell it was leaning pretty good but didn't really bother me at all. So I'm sure the antirock will do just fine.

I have my Antirock set on the loosest setting, and all I do different on the road is to get into the curve and load up the suspension before I touch the gas. I don't feel any severe lean but I don't go into a corner *hot* haha.

The payoff, of course, is only airing down and not messing around with linkage before and after hitting the trails.

I don't air down because I don't have a way to air back up. Could probably do tougher stuff aired down but I still go where everyone else goes on the trails.

A small air compressor isn't going to break the bank. Not airing down when offroad is hard on the tires, reduces traction, makes for a significantly stiffer/bumpier ride, etc.

The anti-rock and the stock (anti)sway bar are exactly the same, except the anti-rock is nowhere near as stiff, and complements the suspension in regards to traction offroad much more than the stock bar. The way an anti-sway bar works is by resisting movement. So when a rock is pushing your tire up, and the other tire comes off the ground with no sway bar at all, when a sway bar is connected that tire is pushed down onto the ground. Now the stock bar was so stiff it didn't allow hardly any uptravel unless you had a TON of weight on that corner. With the anti rock you keep all your uptravel but with the benefit of added stability from the action of the smaller rated antirock sway bar. So you keep traction and suspension travel. That is it in a nutshell. Geimans link is good.
