This is a shout out to those looking to replace their leaky questionable rear airbags. I have galvanized Sullybilt kits in stock that can be to you anywhere in the continental U.S. in 3-4 days.
Kits cost $434 including shipping of $34 for both sides of the rear and include all needed hardware and instructions.
The 9294 Firestone airsprings are IN STOCK at Applied GMC 1-800-752-7052 for the same price you can buy them from any who knows who e-retailer, $139.5 per side.
No tax if you are outside Washington State ---
Total cost to your door in less than a week $713 for a new rear airspring system that-
1. Utelizes a higher load rating spring than the original
2. Operates at a much lower air pressure (typically under 70psi) reducing compressor strain as well as lifting time.
3. Mates well with the wireless air system built and sold by Jim Hupy
4. Offers a firmer yet more supple ride with reduced body roll under cornering conditions.
5. Can be installed in an hour with basic hand tools anywhere you can park your coach.
6. Requires NO modification of any other part of the rear suspension system than the air bag itself.
7. Allows for retention of one original air bag to carry as a quick change spare.
8. Has an integrated bump stop to allow travel with a damaged air spring or line which allows you to DRIVE TO A SAFE PLACE and conduct repairs.
9. Prevents wheel well damage in early model coaches from blown or deflated airbags by restricting tire penetration of wheel wells.

Replacing my airbags with Todd's system was, by far, the easiest upgrade I have attempted so far. less than an hour both sides.

Just a couple of minor issues that I have come across with the sully system.
1. If you are running 245-75-16 tires, clearance is a little close on the stand-offs that the mounting bolt goes though. I chose to cut the corners a little for more clearance.
2. Some coaches may require a bracket that is offset to the outside about another inch so that the bag does not rub the wheel well on the inside. I think Todd has fixed that problem by making them all offset about an inch.
3. Get the Firestone bags, not the other brands that you may find on eBay or elsewhere. While specs show that they are identical, in actuality, the "other" brand that I got was about 1" in diameter larger...hence the clearance problem.
4. Fully inflated, the bags do not raise the coach quite as high as the original's do.
I am running between 38 and 45 lbs in my bags, and have not noticed any difference in ride between the sully system and the old system. The lower pressures allow the coach to raise up to needed height much faster. Very easy to install, and the bags can be found at most any truck stop. This was money well spent. JMHO.

I have to agree that the Sully system was money well spent and have had no issues.

The max lifting height of the Sullybilt system is 1/4" less that the oem when measured across the bogie pins to the ground.
There has been a re design of the Sullybilt system since the original offering to address inside clearance issues to the wheel well on SOME coaches. The current design is now the standard and fits all coaches without ANY modification even if running T skirts.
There is no need to modify anything if you go up a tire size if there is no tire contact to the plate. The spacing between the tire and plate is constant and does not change with suspension movement across its travel range. Obviously if REALLY big diameter tires are installed a clearance problem is possible but at huge diameter increases there will be a multitude of clearance issues to the front body as well as potential to over tax a relatively anemic stock braking system.

And that is OK too. If I had the spare change I would have done a quadrabag, but with the laundry list of repairs upgrading was a luxury that needed to wait. Without the single bag option, the coach would have had to sit while the cash was saved. Anything that gets me on the road faster...

Steve, you know I feel same as you do. I have the q bag. I have been very fortunate to have most every upgrade that Jim sells. We have no "show quality" coach but we try to keep it dependable for long cross country trips. Dont remind me about the two blown engines. But, I believe the Sully setup to be the perfect replacement for many folks. Cheap, reliable, and anyone can upgrade the coach in their own driveway. I bought the qbag for a very different reason than most and gave up brand new original bags. Even today, with all of the options, my personal choice would be the q bag setup. Absolutely no reason to let yourself pay 800.00 for 2 original bags,,,, unless that is just your personal preference. And, that is just "ok". We are blessed with people who are smart enough to help guys like me keep these old machines running.

And kudos to Sully for taking the time and effort to bring a solution to reality. I do like the idea of truck stop availability as well as the bump stop. When the time comes I'll look at all the options, and options are a good thing to have.

I'm trying to digest all of the thread but let me say this-- if you have a quad bag system, you now are modified to use an air bag readily available that it frees you up from having some special bag. Try some of the other systems do that too, the pickup in safety and performance I feel trumps them and buying an original or a retrofit original bag still ties you to some special niche dealer. Yea, that would include me but I would rather you have a quad bag system and now not have to call me in the middle of the night (I will answer the phone) is you need an air bag. Getting them from most anywhere really is a great thing, wish many of the other unique parts were redesigned to do that (1 ton suspension does that).
We can probably go on for weeks people saying why they did what they did and it's human nature for you to persuade folks to do things the way you did them. I will just say I installed a blue million of the first 4 bag system, found a shortcoming and was involved in redisgning to the quad bag set up which I feel is about the best thing going. I appreciate the other ideas and applaud them but for my customers, the quad bag has so many features it's a value added expense for sure.
As far as diluting the market with multiple products, hey we live in America but it sure would help so many in this industry and probably go a long way to bringing us together if we could get behind a product and support it to the community. Probably will not happen on air bags but hey, there we are...
If any of this is refuted on subsiquent posts in this thread sorry but I have not finished reading them all as yet.

Or you could keep one original bag (which you probably already have) as a spare you are unlikely to need then swap it in minutes and call Kanomata who will have a bag waiting at your house or next stop on the way.
