That picture now looks like the Zone Track Bar, the welds match their install instruction pictures.

Those are pics of the sway bar mounted to the axle, need the pic of the sway bar mounted to the frame which you should be able to see from the side of the truck, not underneath.

 

On the Zone install instructions, look at figure 14 to see the added bracket to drop the sway bar frame mount. Your sway bar is probably not centered.

 

 

So the linkage should be straight up & down?

 

This thread has confused me a bit! It looks like you need a trac bar drop bracket. When you install longer springs, which drop the axle assembly, the trac bar causes the axle to shift to the passenger side. A trac bar drop bracket lowers the trac bar, allowing the axle to return to its original position. Your trac bar and drag link always sit at an angle, stock or lifted.

 

Looks like sway bar isn't centered in mounts pushing to one side, also did you get drop brackets for sway bar , think you need to drop sway bar with lift , I did on my 2.5 lift it came with drop brackets

 

Here is the link to the install instructions, look at figure 14 to see the mounts for sway bar to frame.

If those mounts are in place then you need the shop to center the sway bar into the mounts.

 

The zone kit has a modified trac bar, eliminating the need for a drop bracket.

I'm guessing the sway bar does have drop brackets, otherwise it would still be centered because it wouldn't have been unbolted. Installer just missed center when putting it back in, causing the links to lean like crazy. I'm guessing they installed the sway bar before the trac bar and the axle was hanging way off center.

 

On second thought, I thought I saw a bend in your trac bar, but after looking at a zone stock photo, that bend is pretty pronounced, I'm not sure they did install the trac bar? Does your trac bar have a big bend in it like the one in this picture?

 

We need to see a pic of the sway bar where it mounts to your truck frame

 

stand far behind the truck or have someone follow you as you drive it and see if the front tires are in line with the rear tires, this will tell you if the track bar is correct. If it isn't it will dog track.

 

I made an incorrect statement earlier. Without a trac bar drop the axle will move towards the driver side, not the passenger side!
