There should be a manufacture label plate on the suspension assemble with a part number and serial number. If you can find it (it take some looking) then contact the manufacture and they can give you the correct information for the air bags. Based on a quick search your suspension might be.

Front HOLLAND/NEWAY IFS-114
Drive NEWAY ADL-120 & ADL-123

Go to their web sites and see it they tell you where the label plates are located.

I did this on my MAGNA and the information Ridewell Suspensions provided base on the label plate information has been invaluable.

Had a nice discussion with Kevin and followed it up with a truck mechanic friend of mine. I believe I’m good. Bags hold air, no flaking of the rubber upon touching, no cracks.

Contact Kevin Waite in Junction Ciy, OR. He can likely locate some bags for you.

When you call Winnebago/CC try and get to speak to Greg Bootes. Greg is usually able to identify most any part if you provide your coach serial #.

I happen to own a coach that absolutely requires that the airsprings in the rear suspension are functional. That is all it has and if one goes out (on my coach's vintage) it cannot be moved.

The real answer to your question is very dependent on the model and manufacture of the specific part. The OE for the coach had a life of about 20 years. The newer replacements seem to only last about 15 years. I personally would have to go with current manufacturing processes and vote that like tires, start worrying at 10 years.

It caught my attention that you must have over 35 years on your coach to answer the way that you did. I am surprised at how many of those old GM coaches are still on the road. I wonder if my 2013 will last even half that long. Keep her going as long as you can!

I drive a commercial truck part time, and its a 95 Kenworth with 700k on it. Just put the 2nd set on it, and he's owned the truck since new.

I changed out the springs on my mh 15 yrs ago and it will sit in my carport month after month and not loose a lb of air, fired it up today after sitting 16 months and still sounds the same as it did when I bought it, air pressure had not dropped a lb, has air suspension from FL70 Freightliner truck that I put in myself for a smoother ride and has never let me down yet. Bags still look good after 4 trips to Alaska and 2 to east coast plus numerous trips to Yuma. Milage now @ 100,000 miles.

What you see on the outside is a protective covering and not the actual air bag

Thanks for the replies. My mechanic says the bags look good but at 14 years I think I’ll change them out.

I believe mine are original. 20 years old and hold air very well and also apear to look good.
