Reyco air springs

I need to replace the rear air bags on my 02 Eagle with the Mountain Master chassis and Reyco 240AR rear suspension. The OEM bags are Firestone W01-358-9966. Everyone is out of stock (Spartan #1919-DD4-001, SD Truck, Truckspring, Stengel). Firestone will not be able to make them till late August.

There is a Automann crossover part AB1DK23P-9966 available that is supposed to fit but looking at the specs the min and max travel measurements are different. The minimum is what bothers me since that sets the coach height when deflated.

Has anyone installed the Automann equivalent? My bags are still OK just old and showing signs of dry rot. I plan to hold out for the Firestones but not sure they will even be available by November. Wanted to see if the Automann cross would work in a pinch.

Thanks

There is an older thread concerning Firestone replacement air springs. The OEM springs are NLA but Firestone recommended a current spring that had a 1" taller bump block inside and told the owner they would work just as well as the originals.
Results from using the google search box at the top of this page. This is only one such thread:

I need the same bags and have called all over the country and they all say the same thing. Out of stock and Firestone not releasing any till mid to end September.

For those of you in need or interested, the only option available to replace the Firestones W01-358-9966 right now is the Automann AB1DK23P-9966. The Firestones won’t be available for 3 more months. The operational travel distance is slightly different but other dimensions look to be the same.

One of my bags is damaged so I have no choice but to install the Automanns right now. I will let you know how they work out in case someone else runs into the same situation.

I just purchased automanns looks like they are going like hot cakes. I kept my Firestone’s on back order hopefully they will also come in. Cross referenced Click image for larger version

I am not up to speed on who is making individual components or final assembly of the Firestone bags but there is a difference. I just received the Automann bags and they have plastic bases. My original Firestone’s are aluminum.

It is quite common to have a single manufacturing plant make basically the same item under different brand names. The named brand company may call out certain specs that are different from one brand to another. I do know that the travel distance and deflated set height is different so they may be made by the same company but they are not the same.

I plan to contact Firestone and/or distributor in a few months when they become available to see if they have aluminum bases. If so, I will changing them out again because I’ve heard about some of the plastic bases cracking without a full metal support plate underneath. The Reyco suspension only has 3 inch wide support arm. I am skeptical if I should use them at all. Safety is a huge concern.

Thousands of air springs are running with composite bases. It's only a issue when the base doesn't have full support.

Don't install them w/o a metal plate under base for support. Reyco has a part number for the plate, but I couldn't find it...

When I replaced mine, I attempted to get them from Spartan, but shipping to Florida killed that. However they gave me the part number. I sourced it local and they were composite bases.

Adding a steel plate under the base isn't as bad as sounds. I have the means to build my own, but any local welding/fab ship can whip a few out. Mine have been under coach for 5 years.

In today's hard to get parts world, I'd not be scared to use them at all. Just add the metal plate.

Just received my automann bags today with composite bases. I noticed yours are Firestone with composite bases. When I talked to Spartan a couple of weeks ago I asked about that problem and was told bases where redesigned years ago and no need for steel plates.

What does it matter if when air bags are deflated the MH is say 1 in off? Inquiring minds would like to know before I install my automann bags.
