on the crawler it works great. I have 2 heims at the axle, then a shackle I deisgned with 2 heims too. I will be changing it out with a bushing where the shackle mounts to the frame, to stop the side to side it wants to do.
you will want whatever you do to be around the same length as the DS. my antiwrap bar is about 6 inches shorter than the rear DS. no issues so far
now I my dually I will be doing like ironman did above.
