Anti-wrap bar retrofit
 
1 Attachment(s)
My anti-wrap bar is severely limiting my rear suspension. I'm thinking of cutting off the exising bushings and installing 3 these heim joints in their place. What do you think?




I'm looking at these rock krawler heim joints. I'm thinking it will let the bar turn and twist while keeping the axle in place.

This is my anti-wrap bar, the bushings really only allow it to move up and down.

No idea but isn't that point? I am asking because I do not know, isn't the point to keep the axle from twisting?

It may help.
I run a heim at the shackle side and I think it helps.
I went with a much cheaper heim and have not had a problem with it.

i think he means its not letting it flex proper, when the side with the bar tries to flex up or down it acts more like a sway bar limiting the up and down movement due to binding at the simple bushings. The point of the bar is to prevent rolling forward or backward of the axle

i'd swap and due away with the bushings if it was mine

I have been curious about this. Waiting to have problems with axle wrap after my V8 swap and I've been meaning to look into it more.

I may try those him joints. Anything is better than what I have now.

Correct, the axle will travel up and down but the problem is whatever one side is doing, so is the other. The rear wheels want individually flex.

I also run one heim joint on mine, at the top of the shackle. That's the only place u need one and it does not limit my flex at all. It can tho, depending on ur setup. The anti wrap bar u have shown allows for zero movement. Just one heim joint added to ur setup would fix the problem quick n easy .

The bushings add a LOT of shock prevention to the system. The single heim for flex on the shackle end of the wrap bar is plenty to prevent binding, and the other three points being bushings dampen the shock loads a bit without allowing much wrap. The trick to minimizing binding is have the bar as close to the drive shaft as possible. In my case, the axle brackets are on the left, right next to the carrier casting. I modified the inner of those two axle brackets to allow the nose of the bar (the whole shackle end) to be angled a bit so it's even closer to the vehicle center. I've seen photos of my truck taken by others that show I'm not limiting my flex at all.

Another thing is to monitor the ride height a couple times a year. I disconnect the shackle and see if it is still the proper length to not force the axle to an unnatural position. As springs age, things can change a bit. I've re-drilled holes twice in less than two years.

I'm going to go with the him joint on the shackle side, that makes sense. I know my springs have sagged a little in the back as well. I'm going with RE SOA springs soon and will rework everything then. Never thought about it not letting the axle sit right.

Thanks for the help guys.

I finally got a chance to pull the Jeep in the garage and start on some much needed maintenance. The anti-wrap bar does have a heim joint at the shackle side. I took the bar off and my flex didn't change much. With the Jeep in the air I unbolted the shock from the axle, I still had 2-3" of shock travel which leaves my springs as the culprit. They are just to stiff. So what do I do? Do I take a leaf out of them? Do I run front springs on the rear as well? These are crown factory replacement springs I put on when I did the SOA conversion.

Back up to the beginning, since you now know the start of this thread was on the wrong foot. Why do you think you need more flex? Is there stuff on the trail you're not getting over with the two lockers? Don't just say I need more flex like rich people say I need more money. :cheers2:

I removed the bottom leaf of the RE rear SOA 6 pack leafs to help soften the back just a little.

If the leaf clamps were opened up and a hole drilled in them with a capture bolt & nut as close to the clamp ends as possible, that would help as well.

I'm sure that worked Joe, though RE recommends removing the 2nd from bottom of it feels too stiff.

The springs don't move much at all, there's no articulation in the rear. I have original factory springs in the front and the articulation is great. I tried to jack up one side and couldn't get the rear springs to compress much at all.
