[GMCnet] NEW SULLYBUILT BRACKETS WITH AIR BAGS
Mike Miller
I noticed a post in the swap meet section. As it looked like it belonged here, I reposted it. It is the author's (rollis20) 3rd post and figured he needed a break... this time. :twisted:

> By late afternoon Friday I had everything needed and had already removed my old ones. So I began the installation. It was not long I had everything ready for a test drive. The new system required a lot less air to set the motorhome in the travel level position. That means that the ride is softer with less wear on the bags. The cost was much less than the original if they were available or any other offering for that matter.

brakets and baught the air bags on E-bay from
Airsprings (no shipping charges) at $118. The installation was very easy.

I've looked on ebay and the airspring site, and can't find specifics (part #'s) on the sully built bags. These sound like a good replacement. Would any one have the specs on building the brackets. Sorry if all this was once posted and I missed it.
I had considered the quad bag set up, but have heard it rides quite stiff and rough. And then there is the cost.
Any opinions from quad bag owners would be appreciated.
Thanks.

I've heard that the Quadrabag ride is about the best you can get. There are a bunch on here who have them, so just wait - you'll be hearing from them soon, I'm sure!

Did you replace the shock absorbers when you installed the Quadrabag system? Some of the improvements you list such as the bouncing and wagging are typical of failed shocks(the bouncing especially)

I saw where Chris posted something like that the other day. I do not understand how he came up with that conclusion but he is entitled to express his opinion.
We have had the Quadrabag since 07. I love it. The ride, on our's, is perfect. I had almost new original bags on the GMC when we went to the Q. bag. I did it for safety reasons but have been quite impressed with the ride. My original bags were bouncy. I did not like that. The Q. bag is more firm so the the back of coach does not bounce like a ball when I cros railroad tracks and the like. With the Q. bag the side to side swaying of the tail wagging the head has stopped. Overall the ride and driveablity has improved a lot. We have about 35,000 miles on the Q. bag. I would never consider going back to a single bag system. Now, if we were "weekenders" maybe I would not have gone to the expense. Glad we did it. Would do it again.

I think the main difference between systems is one relies on the design of a single bag to both carry the load AND provide the rigidity necessary to keep the bag between the bogie arms. The dual bag (Q-bag, 4 bag) system employs additional structure to keep the bags in place. Hensley split the baby so to speak and relied on the bag and compression alone to hold the bag (that I think was deigned for vertical application)in place.
I looked at the dual bag setups and thought the additional structure added unnecessary complexity and the possibility that the design goal of easy welding-free assembly might compromise the strength necessary (but not being an engineer, that's merely eyeball speculation).

In speaking with engineers at Firestone I was informed that this spring is demand built meaning that they are not produced until an order is placed. They will tell you to expect to wait up to three weeks but I had mine in less than two. I like the idea of a fresh born airbag. Worth a little wait to me.
I have stated in earlier e-mails on this forum that I approve of personal individual reproduction of my design for personal use. This is a hat tip to the weekend warrior shade tree fabricator as I consider myself one. If you have questions, don't hesitate to contact me.

I suspect all these concepts have different spring rates with different resultant ride and roll rates. The amount of air pressure required to hold them up is a tip-off. Without making any judgements on which is better, the subjective handling will be different. Even then, it may boil down to personal preference.

What company built our original air bags? Wasn't it Firestone?
If so, why couldn't they build exact duplicates upon demand?

> Mark G has posted measurement specs for his original design including a picture of the plate drawing. The Sullybilt system is similar with a few key changes in design. Info on the Sullybilt system can be found on my website. www.bdub.net/sully/ The spec sheet for the firestone spring is there as well. If you are searching for the spring, www.truckspring.com has them available.

I guess I am also afflicted with a little of the "overkill" disease myself.
No, on the shocks. There was just too much spring action in the original bags to suit me. I ran with and without extenders. I do know what you mean though on old warn shocks. I had a bad bouncing in the front of the coach. Put on new KYBs and that eliminated the problem. To get propper rear ride height, I normally run 75-80 lbs in the Q. bag.
It is great to see so many replacement options for the bags. There is something out there to suit everyone because we have so many "thinkers" in our group. I am always happy to reap the benefits of such a great group of designers here on the net.

replacement systems should edit the document to list Sully's system. Sully,
you should provide information whoever the dude is.
As to ride -- it depends on what you want. Firmer or softer and whether
you're always towing a vehicle or not. Some people like riding on rails and
other like riding the waves.

It was Andrew that put the spreadsheet together, see new Suspension System Comparison message. He hasn't posted since October,
hopefully he's OK. I sent him a PM asking him to take the credit!

Thanks for the message. It got me off my duff to bring the spreadsheet up to date with all that I could find. As for credit, I'm just the scribe. All the work was done by others.
It looks like most of the popular systems have had price drops in the last six months. And I've added Sully's, of course.

Sully, take a look and let me know if I've captured your system properly. I found the airbags for $140 online, and I used the price for the painted steel brackets, since that's the most directly comparable to the others.
Thanks!
