Cj Custom CJ7 Front 3 Link Panhard bar problem

Installing a custom 3 link from barnes4wd.com. Got everything in but the panhard bar is going to be a problem. The axle bracket will be way to close to the bottom of the frame. I can fix the problem if I put two 45 degree bends in the panhard bar.

See the attached picture. Will I have problems?

What size tube will get the bends? If its .120 wall 1.5" tube then yes it will bend under a hard side load or a impact.
Can you build a tower off the axle to raise the mount up off the axle tube. This way you can use a straight chunk of tube and now just chunk of .120 wall 1.5" tube can be used without the fear of bending.

Or over build and use some .250 wall 1.5" with miter cuts and re-welded joints.

Assuming your drawing is actually correct and drawn to scale, you will get a warm welcome to bump steer city.

He's a link to one we're working on right now. Perhaps looking at it will help you see how we are doing it and maybe you can adapt our approach.

The Panhard bar in the drawing will actually be in front of the axle.

It was my understanding that if the overall length from left to right, no measuring the drop, was the same as the drag link and the angles were very similar it would eliminate bump steer...

The track bar and the drag link need to be observed from only their mounting points when comparing them. They can be bent into a pretzel in between the ends and it won't change how they behave (well ignoring the fact that they will want to bend more easily of course).

Imagine the track bar isn't bent and compare that to the drag link. The two angles are very different at that point.

Ideally you want the track bar and the drag link to be parallel, the same length, and in the same plane (one is directly behind the other when viewed head on)

Maybe try to find some builds on here or pirate that use a passenger side drop axle in a TJ and see where they routed the track bar.

That may help out a bit as well.

Mounting point to mounting point of both bars need to be parallel....not sure why you would think anything else other than that would result in good steering?

Mount the axle end of the panhard bar to the inner C.
