On the PST website and even the Hellwig sway bar the middle hump does down and under the center section of the rear end.

I had mine put together line that but before drilling the holes I looked to see how much mine hung under the housing and it seems to be about 1-1.5 inches below the housing. Has anyone had problems with it catching or hitting anything while it hangs that far below?

Has anyone mounted it the other way with the hump in the sway bar going the opposite direction? It seems to clear the rear center section just fine and gives better clearance with it flipped just dont know if it could be run this was.

@PST maybe you have some insight?

Thanks!

Edit forgot pictures

I run a Hellwig on my Duster, it's about even with the bottom of the pumpkin. I haven't had any issue with it being too low. It's still higher than the header flanges by quite a bit, and my Duster has less than 1" of rake front to rear.

I'll get a picture of mine for you in a little bit.

I may have seen yours before, or at least some of the hellwigs. My headers already hit like crazy on some bumps even after going taller tires and raising the front, and I'd hate for the sway bar to catch on something and get ripped off :)
 
Hey Doc be carefully not to tighten those u bolts too much

I bought an 8 3/4 rear housing only to find the PO had used round u bolts instead of the factory flattened u bolts. Center of the flashlight light is the indentation in the inside of the steel tube.

I would love to know what the factory flattened ones look like? These are the stock ones that were on my 7.25 housing they are rounded?

Right now nothing is tight but 45ft lbs is what FSM states

Your wish is my command

The point is lbs per sq inch. A perfectly round bolt spplys a tremendous amount of psi to the tube. The flattened ones spreads it over a larger area do the psi is lower, for the same nut torque
 
Here’s a shot from the back of my car. The top of the Hellwig bar is basically even with the bottom of the housing, so the diameter of the bar is below the housing. But you can see my headers and even my T56’s transmission mount are lower than that.

I've seen both the round and flat come right from the factory. I'm not sure there was any rhyme or reason there. As long as you don't over torque, that's the main thing.
 
Round might be used on Dana 60 or other with steel tube in cast iron center section, but the formed tubes of the 8 3/4 are not as robust
 
Hey Doc, I noticed on your mounts there is about a inch or two between the u channel mount and the axle tube. In 72bluNblu's photo the u mounts are more like a spring purch and move the mount almost touching the tube, looks like an inch or two

Mines not tightened down, it's just resting there in both pictures.

I was thinking that earlier as well that tightening everything may move it up some as well.
 
Have you sat the car on the ground and checked it, or is the jack in the picture pushing the rear up to ride height?
 
I flipped it back to where the arch points down. It sits pretty good after tightening it up. (Its jacked up again now because I'm going to try and roll my fender)

Thanks for the help!

Driving the car for the first time after the sway bar and radiator installed and holy moly it's like a whole new suspension system was installed on the rear end. Only thing the rear suspension needs is to sit a little higher now.

The rear end feels so much stiffer and the rear end feels so much more planted to the ground. I absolutely love it!
