I bought a new to me 2008 F150 recently with adjustable air shocks. I have no idea what type of shock it is to find out what PSI I should be running in them. The air hoses feed to a common valve stem by the license plate. Anyone have any tips? Thanks.

They are not shocks. They are called air bags. Good for leveling the truck when you have a load on.

Or more accurately, air helper springs.


I don't know the brand for sure, but they might be Firestone RideRite.

That's one of the options for the air hoses. The fanciest is an on-board air compressor with controls inside the cab to change the PSI in the rubber springs. The simplest is a seperate shrader valve for each spring. Yours is a middle of the road option, more convenient than crawling under the truck to adjust the PSI in each air spring, but not as convenient as having the controls in the cab tied together with an on-board air compressor.


As to how much PSI, have less than 5 PSI when unloaded. When loaded, add enough PSI to remove almost all the squat from the rear suspension.


After you know the brand of your air springs, go to their website and download the install and operating instructions for those air "bags".

This was the info I knew of when I installed Firestone Air Springs on my F250.

Must have at least 10#s of air in each one. I kept 20#s

Take a measurement of your wheel well lip with 10#s in it. For me it was 42 inches. So if I put 1000#s in my bed, I might have to put the bags at 50PSI to bring the ride height back up to 42 inches.

Never put more than 100#s of air in the bag. I got close when I overloaded my truck and I didn't care, just had to get the work done. I think I had 90#s in each.

Thanks for the info. When I got the truck there was no air in the shocks. I have been keeping them around 8# so I will up it to 10#.

I found this kit which seems to be very close to what I have on my truck but it is only for a 2004.

I wouldnt doubt that the previous owner got creative and put the kit on my 08.

Another question. If i wanted to remove them would I just need to get the rubber stops for the frame that hit the leave springs.

^^^Exactly

I could be wrong, but it looks like you still have the bump stop. The round object on the right side of the photo.
