Tom, the only reference I find to 'sway bar' for pre-ZF coaches seem to be from Gordon Hummel talking about his 1991. I need to talk to Newell tomorrow. I will try to remember to ask about sway bars on pre ZF coaches.
I had Newell add an anti-sway bar to my 2003 about 6 months ago. Wow! What a difference! Before when I went into a curve with the road tilted the wrong way...I was holding on for dear life. I felt like the coach was going to tip over. Now with the rear sway bars I am much, much more stable. (Already had sway bars in front)
Before the sway bar, I would never get over 70 on interstate...Now, I can go as fast as the front tires and my bank account will let me go.
I think it was $2500 but don't hold me (or Newell) to that. The bar itself is a u-shaped thingy that required a little welding to mount the brackets...but it did not seem overly complicated.
I have done a lot of upgrades to my coach...but this is by far the biggest bang for the buck!
Talked to Chuck Clark, parts manager, at Newell this morning. He said that service has installed some sway bars on pre-ZF suspensions. He said that they were special ordered from IPD he thought.
You might want to talk to Jim Gerring in service department. When I did mine it was not a special deal. ActUally an afterthought on a regular service visit.
That particular receipt is not among the rest of my Newell paperwork...but I will keep eye out for it. I will also try to bug the service guys to see if they can find and reprint the receipt.
In the meantime, here is picture. The bracket to the left was welded onto frame and the right was bolted to suspension.
