Hi... My new to me 92 PA has front and rear air shocks that I cannot find info on how high to pressurize them. In a some previous forums, I see the "Red ones" are preferred. I have red ones on the front. They are at 50 pounds. (I have heard 70-90 pounds is about right) Im not sure (yet) if I have originals on the rears, but they are only at 25 pounds.
The coach tends to "float"a little going down the road and I suspect this is the cause. I want to add pressure, but I dont want to blow them up. Can anyone help? Thanks in advance!

Hi Glen,

Not sure I would call this a definitive answer but go the following site and click on the instruction link (also included below):
Firestone 4100 Coil-Rite Air Bags - Chevy P30 Motorhome Class A | $102.64

http://www.firestoneip.com/site-reso...ation/4100.pdf

It says 60-90 psi for the front bags on a P30 chassis. I replaced the front bags on my P30 (1994 PA) this summer and have been running them at 75 psi. I do not have bags in the rear so can't help there.

I saw the advice to have the springs replaced but didn't do it due to the extra work involved. In hindsight, I can see that this would have been a better route to take as both front and rear springs on my rig are tired.
