So I could not find the thread on someone who was asking about putting in airbags and weather or not the springs needed to be taken out. The answer is no. I just took the bottom bolt out of the shocks, jacked up and pushed them in.

I am happy with them as they level the truck back out to stock from the saggy rear that I had before. Here is a pic of 20 psi in the bags.

 

do u have any pics of the setup and what kind of air system are u using

 

Not much of a setup really. Just the air bags, some hose to a PSI gauge and a valve. The valve you get in the kit is like a tire valve. I just pumped it up with a compressor. I am going to add some on-board-air as the AC pump is just sitting there not being used.
