Did the modification today and did it go smooth. I am pulling our trailer and it did not sway as much when cornering and really held better in turns!

THIS FIX/MODIFICATION IS WHY I JOINED FORUMS! Looking forward to more good advice!

Finished the rear yesterday by replacing the links with Helwig adjustable links. Had to crank them almost all the way down to keep the original geometry. We will see what difference was made by this one last mod.

I don't think you will even notice the difference. Actually, geometrically, it should be slightly worse than without the Helwig links. Without the new links, the anti-sway bar is ever so slightly shorter than with them. You see what I mean? As far as the bar hitting the dif, unless you are jumping those motorcycles, it won't happen unless the rear jacks are fully extended...... like that matters?

I hadn't done the mod to the rear yet anyway so there should be some difference, As for the Helwig links, I got them for free with points so they are more for me than the MH.

It should be interesting to see if you notice "more of a change" by doing the rear after driving with only the front done. I did both at the same time with only having driven 5 miles home from the dealer and not knowing about the sway or mod.

I think I've read all the posts, and can't recall anyone having an adverse effect.
Some, including myself noticed that the bar hits the diff at full jack extension, but nobody has posted that it caused a problem. I could put the front links on the rear, but with only ~1" longer, it's not worth the trouble.

I just did the quick fix on my front sway bars and I talked to my mechanic about the fix and I did some extra research.

Here's what I've determined. The sway bar's function is to transfer the force of the compressed spring on one side to the other side of the vehicle. It does this by using the downward force on the outside of the turning wheel to twist the sway bar. The twist in the sway bar acts to compress the springs on the other side.

The long and short of it is that the reason this fix works is because it shortens the effective length of the sway bar, thereby stiffening the bar and transferring more force from one side to the other.

This is important for two reasons: 1) the adjustable links probably don't make any difference. Since the issue is twisting, the angle of the sway bar shouldn't matter. It's simply bent that way to keep clearance from the underside and leaf springs. 2) The stiffer the sway bar, the less independence each wheel will have. So if you hit a bump on one side, the other side will react in concert and feel the bump.

I haven't driven the coach since I made the change this afternoon, but I can't wait to try it. I'm sure the tradeoff between anti-sway and independence will be well worth it.

Totally agree (the original links would have worked fine), the only reason I used the adjustable links was for MY desire to keep the original geometry, nothing more, nothing less.

Since your hands were already dirty, and you had the tools in hand, you shoulda done the rear while you were under it.

I thought about it, but I wanted to get home (the RV is at the office) and I wasn't sure if I'd need shorter links for the back once I flipped the Z-bar. I already have a tiger trac, track bar installed in the rear and figured it wasn't as pressing to do the back.

Is the back as easy as the front? Do I just flip the z-bar and reverse the holes?

Yep, and yep. It may hit at full jack extension, but it won't hurt anything. If anything, you need longer links in the back.

Not by much though, about 1/2 inch.

Drove about 30 miles today after doing the MOD to the rear (front done a while back, see earlier posts), not a big difference but the rig was unloaded and "dry." About to go to New Orleans next week, that will tell the difference!

I have added the Firestone air suspension to the front and it has made a great improvement to the sway and helps when trucks pass me or I pass them.
