What should the PSI be for air bags?

The psi will vary with how much weight your are towing or hauling and the condition of your trucks suspension. While we are discussing air pressure, we have to mention minimum air pressure. The most common cause for failure in air bags is running them without the minimum air pressure. This causes them to bottom out, tear, etc.

Is there a problem with the coach air system?

The air gauge on the dash is reading about 50 psi. All the air is out of the air bags and the coach is sitting down. When I start the coach the pressure comes right up no problem. This is the second time I have noticed this happening. My question, is this normal or do I have a potential leak?

Why are the air bags not inflating on my truck?

I have a 2000 fld 120, I noticed the warning air suspension light came on inside the cab, and the suspension bags are not airing up. The tanks are building pressure to the normal psi. the tag axle still functions to air up and down, Does anyone know if these trucks have a relay for the suspension bags, or can hint at , why they’re not airing up.

Yes, if you have air leveling, most systems have a 12 VDC compressor. If it runs for more than a couple of minutes every hour, you have a problem. Could be the compressor, could be the small auxiliary air dryer on it or an air line.

What should the air pressure be on Firestone air bags?

Thank you Other than saying that the air bags need to be kept between 5 and 100 psi, Firestone does not offer much in the way of specifics. The instructions mention that as a general rule of thumb, 1 psi will support approximately 40 lbs of load.

When to use an air compressor for air bags?

We recommend an air compressor kit if you plan on using your air bags frequently and tow more than a few times a year. Air compressor kits allow you to inflate and deflate your air springs from the inside of your truck and monitor the air pressure at all times.

When to inflate or deflate your air bags?

Inflate or deflate your air bags until you have the height you want. If you are planning on filling the back of your pickup truck with logs, obviously you’ll want to over compensate for the upcoming load. Now that your truck is level, take if for a ride and check the ride comfort and stability. If it feels stiff you may have too much air pressure.
