Pickup Truck Owners,

I just installed a set of Firestone Ride-Rite rear air bags on the Dodge Ram 2500.

What kind of air pressure do you usually run in your air bags?? Loaded and unloaded, please.

I ran a common ?? line up into the cab. I have an air regulator with a 5-60 psi range. It is self relieving and I hope to use it with the onboard exhaust brake compressor and an inline check valve. The compressor only puts out 65psi anyway.

Thanks in advance.

Kamper Dave

i have a set of the double convulated air bags and i can go up to 100psi. (60psi. is usually where i keep them for my camper). i had a set of the ride rites on my light duty chevy and i'm pretty sure they were also rated for a max of 100psi.

I have the Firestone bags also. You should keep at least 7-9 # of air in them when you are running empty. As far as how much is needed when you have the 5er hooked on will depend on how your truck sets. You might only need 10# but more then likely you will be up around the 25-30# range.
Set it where you are level and it rides good.
I run about 18-20# but my 5er is a lot smaller then yours. When I had the Lance over the cab camper, I had to run 80-90# to level up the truck.

Thanks Guys.

It sounds like 60 psi might be just fine.

I will order the extra fittings needed and plumb it in.

Yes. The Firestone Ride-Rites call for a minimum of 5 psi and max of 100 psi.



Thanks again

Kamper Dave

It works!

We have the Pac Brake air compressor supplying the air bags via a 5-60 psi self relieving regulator. We needed a piston check valve on the input of the regulator to keep the regulator from feeding back if the Pac Brake systems looses pressure. The air pressure gage was routed up on to the dashboard.

We did go overboard and installed a shut off valve and a valve stem input just in case there are is a failureduring vacation.

It might have been easier to just install a Firestone kit. Guess I am cheap.

Sure wish you could purchase the Firestone Controller without having to buy the compressor also.



Thanks for your input!!

I use about 45 lbs when towing the PP and always leave about 7-10 lbs in them to keep them from flopping around back there when unloaded. You can even put a tad more into the right-side bag to take a little crown out of the road.
