Default BMC 37' Air bag / air spring

A while back somone asked for air bag for the suspension number for BMC.

I was under the front of my 94 BMC 37' today, and the this is the info on it:
Airide Springs, Firestone, AY, (1T15M-0), L

I wasn't under the back to see if the number is the same or not. I have some more work to do on the coach tomorrow before I start traveling again, If I get a chance I will check the number on the rear.

Dan,

I think you are referring to this thread started by Lee Davis: http://www.wanderlodgeownersgroup.co...ead.php?t=2897

Default Air Bag - Air Springs?

Dan,

Yes I was interested in the part numbers from your rear air bags. I was thinking I would replace mine with higher load bags (if indeed they are higher load) and wondered if they might have changed yours out when you got the 22K axle or if they left them the same. What are air springs?. First I have heard of that. Is this something that goes with the airbags or what?

Thanks,

Air springs = Air bags. Just a different name for the same item.

Lee,

I looked all around the rear air bags today. No numbers, no markings, no info on the exterior of them at all. They are different than the front bags.

I wouldn't think putting in the heavier axel would require different bags. The bags "should" be designed for the weight of the coach they hold above the suspension?

My documentation does not detail what all BB swapped out with the axel upgrade.

Lee,

Was Spartan any help?

Did you ask about the air bags on my chassis using my VIN number and your air bags using your own VIN number?

Just curious if different.

My initial thought would be the rear suspension would adjust the air pressure inside the air bags based on the load and the height valve adjustment. I would think what ever bags you have now would continue to work unless you planned on increasing the load on the rear axle.

Not sure if this is right, but it sounds logical to me. Perhaps more informed people will chime in.

Default Air Bags - Spartan

I talked with Wendy Jarvis at Spartan and she sent me a bunch of info on ride height, maintenance, and specs on the different axles (19K and 23K) but didn't have anything on the airbags but was going to check. I sent a follow up a few days ago and haven't heard back yet.

Brad, I did use your VIN and mine to see if the air bags were different. I may have to call her but whatever I learn I will post.

Best

It's been 6 years LOL but wondering if you happen to remember if the bags were different. Mine has the upgraded rear axle and I'm planning on replacing all the bags as preventative maintenance.

I was thinking of doing the same thing .
I don't know if my rear axle was upgraded or not .
