Airbag pressures

[Ted Constantine]

i have had firestone bags with an airride compressor monitor system in the truck for a couple months. I am wondering what others are running for pressures with different loads. The monitor maintains a minimum pressure which is where I leave it for empty. I tow a 14-16k gooseneck and I have been running about 45psi. What is the max pressure anyone here has put in them and what were you towing? What pressures do you run with the different loads/trailers you tow.



Thanks

Ted

It is going to depend on how much toung weight you carry on your trailer. Ideally you wan the truck so sag into the springs about 2" so load the trailer then add air until the truck comes up to about that level. The bags themselves should be rated to 100 psi.

scott and grant thanks for the replies. Grant your rig set up is about the same as what I am talking about- 31' goose with a gcvw of 24,500 +/-



what i would like to get an idea of is what pressures people run with a given pin weight or bed load.



are you both srw or dually?

When we had our Lance 820 (3000+#s), I'd run between 65# to 80# in my Firestone bags loaded, 5# to 10# m/t. I didn't have on-board air, just carried a small air compressor. Once I got my bags set, I didn't have to adjust them much.

im a SRW for now but soon to be a dually short bed. the max pressure for your system is 100psi. didnt see that in the previous post. i dont know my pin weight like i should. have not had time to figure that out. i will the next time i am able to though.

I usually tow a 24" goosneck from 20-30k but I'm running full air ride so my bag pressures will be totally difrent than yours. Can't help you there.

GW That is some trailer. What's in the box? Hope you have the drive tires at 80 PSI! It does look like the Ride Rite's are doing their job.

When mine was installed, the instructions said to measure the distance from the bottom of fender opening to center of hub. This is because the drive line is supposed to stay as near to stock level as possible because of the angle of drive shaft. Also since I have a Gear Vendor they also stress the fact that IT also must be at a certain angle and remain there, or as close as possible. I usually run about 7-8# empty and with 25-2800 pin weight about 65# BUT I keep a cheap tape measure (6ft) in cab for this purpose; and keep it as close to 24" as possible. This also rides better than saging. Or too much lift.

I run mine at about 40# to50# with the 5er on it is about 1400 to1500 pin weight, I run 15# empty.

When I installed my Fstones I aired them to 5psi truck empty, took my buck knife and notched my shocks were the top tube overlapped the bottom tube. Hooked my trailer up and aired up till my shocks reached the notched line. When I disconnected I checked what presure was in my bags for the next time I hooked up. Those little 12vdc air compressures rock-------RJ

when i had E rated tires on it they are always at 80 PSI. i have 315's now but have yet to tow with them and dont plan on anything but around base to work on the truck that is on the trailer. i keep my 315's at 50psi (max for them :-( ) and will be buying a set of 19. 5's or larger with E or higher rated tires, but i want to wait until i dually the truck out before i start doing any rim buying.



when i was married i had a 2 car grage down in Yuma AZ. when i got divorced and mvoed back to cali for the USMC i had to move everything in the garage. it was a pain in the but loading everything into the truck on and into the blazer on the trailer. i didnt have the goose at the time. when i was in iraq i had my folks find that box for me and load it on the trailer. imagine a two car garage that was a shop with 24k in tools in it. . thats whats in the box.



long story just to say all that... . sorry
