Air bags?

I have coil springs on the front, and there is a red air bag inside each. I found a label on the radiator support that says they are to be inflated to between 40 and 60 PSI.

The rear bags are yellow and have inflation stems under the wheel wells.

My question is, about what pressure should be in the rear bags? I put 60 PSI in the front and the chassis rose up a couple of inches.

I put 60 PSI in the rear and the chassis rose up an inch or so.

I'm curious how the coach will ride now with 80 PSI in all the tires and the air bags inflated. This should be interesting.

Thanks in advance!

Probably Air Lift 1000-series bags up front. If so, they can be inflated to 100 PSI and you should keep a minimum of 5 PSI in them at all times. Here's more info on those.

Great test drive!

I set the front bags to 60 PSI and the rear to 70 PSI. We took a 20 mile test ride today and the difference was unbelievable! The ride was smooth, the rattles were reduced to near zero and the ride was crazy smooth! Body roll was reduced by a large amount. I also set the tire pressures to 80 PSI all around. Upon return I checked them all again and they had increased to just over 90 PSI when warm. Major difference on the road. I'm super happy!

Drove it to work today for an appointment with a tire shop. Hit the interstate to and from, drove like a dream. Funny how that works!

Imagine how it would ride with the proper spring and shock on it??
Also to fully inflate the bags... you need to unweight the front end. Have fun

From the looks of it all, the shocks and springs are shot and need replacement. Its on the list.
