1990 40xl air bags
From the build sheet on this coach, the steer, drive and tag axle bags are the same and designated as Goodyear 1R11-064…..which does not exist in Goodyear documentation.
I called Prevost and the steer bags number they gave me is 630172…..which does not cross to a Goodyear (or at least I could not find it)…
I thought the steer bags on these older XL’s are 630259 or GY 1R11-244…..apparently not ?
So…A bit confused with these airbags….anybody with an older XL that can verify what steer bags part number should be and what does it cross to for Goodyear or firestone ?

Be careful Marius because as I recall some early coaches were built by converters who exceeded the stated Prevost axle weight limits. As a result Prevost came out with a service bulletin that allowed different air bags than the originals and I believe added two more shocks to the front end.
I think Prevost is going to be your source for correct part numbers because they likely have records by serial or VIN for the correct parts for your coach.

My memory is hazy, but I know I had to replace the “air beam” on my 90 XL. This is a long single airbag that sits on top of the front axle. If I recall correctly, there are no airbags on the corners of this vintage chassis. That is why the Level Low has just up and down controls for the front, but side to side for the rear. So the build sheet may be erroneous. By the way, after replacement of the air beam by Prevost, I was never again able to raise the front of my bus above ride height. The replacement bag used by Prevost prevented it. There was a lot of discussion of this on the Prevost boards back in the late 90s when these air beams began to wear out.
