I have a 2006 GMC Sierra 2500HD with Firestone air bags. I tow a 34' 5th wheel that's about 11k lbs. How much air should I run in the bags? 100 psi is max.
Thanks, Tony

 

Got them on my 3500, and with a 40ft 13k trailer, i run around 45-50 empty trailer.
40psi is probly a good starting point, relly have to just run them and adjust to suite ya. If you are going on a long trip set them around 60 that way you can let the air out till ya like it. Personaly i got the compressor on mine so I can adjust on the fly to suite me.

 

thaks for the info. I've been playing with different psi's and haven't found the sweet spot yet. I was to cheap to buy the onboard compressor so I do it manually.

 

When i haul heavy i usually start around 60-70 psi and go from there. I also have a onboard air compressor.

 

I'm going to try adding a tank for the air to expand into,see if I can't smooth mine out.
I've noticed that unless I'm hauling something ridiculous I don't need em'

 

I have a 10,000 5er and only put 30-40lb, any more than that is too hard on my back.

 

I am new on here. I was think about firestone on my truck. This will help me out.

 

Get a on-board air compressor, well worth the money.

Did you ever sell the air system off of the F150, that you had posted?

 

I had a set on another truck I used to own, it was a 1/2 ton and I would load that truck with firewood and run 60 lbs usually and it never would drop.
