Running Without a Rear Sway Bar

Think about it as controlling movements. Without sway bars and without adequate shock damping, the body will flop side to side as the Jeep moves through the terrain. The weight shifts uncontrollably towards the downhill.

Add in antisway bars on both ends that also allow for full shock articulation and you create a system that tries to keep the frame parallel to the axles. When the axles articulate in opposing directions, the antisway bars work up keep the frame centered between the forces of the articulating axles. The movements created by weight shift are controlled. Controlled movement aids in stability.

Hey haven't we had this discussion before https://wranglertjforum.com/threads...gineered the Antirock,the weight on the tires.
 
At one point it was everything.



Ever seen a flat fender or early CJ5 on a ramp? They do the same thing. The frame flex was intentional.

Yep.I believe it. TJ frames aren’t so rigid either, I don’t think. I just thought the pic illustrated the frame flex pretty well.

Frame Flex has been around a long time.

From a low speed annoyingly rocky trail standpoint, no sway bars with even remotely good shock valving and decent spring rates you are not flopping uncontrollably all over creation. Low speed in those situations with no sway bars means most of the hash movement of the axles is not transferred to the vehicle. The vehicle is prone to stay more flat, your not lifting tires as often or at all, and your less fatigued at the end of the day from not getting beat up.

Add in any sway bar and your are going to have to compromise something. Full articulation will cost you some level of roll control. You have to pick what you feel is acceptable regarding roll control vs axle freedom of movement. Its impossible to have the best of both. You cant. You have to chose what level of control you want the axle to have on the vehicle.

This whole sway bar discussion really comes down to personal preference and opinion.

Its not a one size fits all kinda thing.

Why do you think so many competitive rock crawlers based on TJs run f/r Antirocks or similar design antiswaybars? Multiple podium finishers like at King of the Hammers with spring suspension Wranglers with Antirocks or similar. I dare say they know what they're doing.

And since I doubt you have seen this video, this is the original intro video by John Currie for the Antirock. You might just learn something if you'll watch it to the end.

Could give a fuck about the racing aspect. They are doing a mix of high and low speed. First sentence in the post you quoted says low speed. Read all the words.

I dont need John to explain to me how a torsion bar works. When you tune a sway bars you have to give up something. You end up somewhere in-between maximum roll control and no sway bar. But you get to pick where you fall between the two.

And please take another read through my last two sentences in the post you quoted.

Did you actually watch the video? I get the feeling you still have not watched it. And racing has nothing to do with why the Antirock is so commonly used. And FYI, John Currie wasn't racing when he won the ARCA rock crawling championship running f/r Antirocks, it was pure rock crawling. Damned few of us running Antirocks race.
