Where to buy Roadmaster air bags??

[rogerlamb]

We are planning a trip soon and the mechanic servicing our 2007 Monaco Diplomat 40 says our front airbags need replacing. He isnt sure where to source them. Can any one advise??
Thx
Roger

There are a few threads here with part numbers if you do a search. Probably the best bet is to pull one and see what the part number is on the bag.

EDIT: The number you'll get will cross to a contitech or firestone bag.

EDIT 2: @jacwjames might have posted them up

My chassis is a 2002 Roadmaster RM8H, not sure it is the same as yours.



I did order a couple of spare airbags from TruckandTrailer.parts a couple years ago.
Ordered ContiTech AS9376
Other then taking one off not sure how you'd tell. I had the parts page from my coach that showed it as a Firestone



Earlier this year I decided to see how hard it would be to change an airbag. Tackled the front passenger side. Wasn't too bad. The one tool I found came in handy was a 3/4" swivel head ratcheting wrench. I did use an impact wrench out of convenience but could get by without it on the road.


I did check the Monacoers.org parts list but it doesn't list for a 2006 Diplomat. Suggest you join the group and ask the question.

Couple years ago I found reasonable prices at Michigan Truck Spring - https://www.truckspring.com/ and SDTruckSprings.com.

I believe this post should read “Air Bags for a Roadmaster Chassis”. I don’t recall ever hearing that they made their own air bags.

Source Engineering in Oregon has a wide selection of air bags.
Their phone numbers: 1-458-207-9442 or 1-541-915-1149 These folks are former Monaco employees and will know what you need.

Stay safe,

My Roadmaster S chassis I replaced all 10 airbags and sourced them on ebay. Cross referenced to Contitech. They work like a charm. What a huge job replacing them was though. Never again.

I believe all the tag axle "S" semimonocoque chassis use the Conti AS8897 airbag. It has a 3/4" NPT air inlet for use with the ping tanks and can be used with a 3/4 to 1/4 adapter without Ping tank.

This link lists cross references for the AS 8897 (not necessarily the best price though)

This one is for the AS 9376 mentioned earlier (1/4 npt)

I second this. I used these exact air bag part numbers for my rig when I swapped them all out this past summer.

Jim at Source Engineering as been recommended by many RVers. I ordered and received two trailing arms from there. Due to my wife's health, I had to postpone removing the old ones and installing the new ones, in that I plan to do the work myself. In the meantime, I sent Jim an email message asking advise/info about supplying me with air bags. Surprisingly, I haven't heard back from him. I assume with the holidays and work load, he has put me on the back burner. I hope he will get time and answer me. All this work is a dreaded task waiting on me.

I bought mine from my local cummins dealer, original firestones at 165 apiece about 3 to 4 years ago
