Update on my Air Lift 5000's…
So Far so Good, Bags are holding Air with no problem (hopefully didn't just jinx myself). I ran each line independent and mounted the valves in the bracket that holds the 7 Pin/4 Pin Plugs, valves come through the top of the bracket sticking out the bottom.
I did decide not to get an air tank and got a small 12V air compressor from Harbor Freight, I got a 12V power port that plugs into the 12V power on the 4 Pin connector so I can plug the power port into the 4 pin plug, plug my compressor into that and add air to the bags in no time, I over inflate a little then let air out of the to bring them down to where I want them, so far works good.
Have not found the need for an onboard compressor, have about $25 in the compressor and 12V power port.
Was reading about the issues with the install of the Firestones, I did my Air Lift 5000 install with hand wrenches and manual sockets, wasn't too bad, may have gone faster with pneumatic tools but many places I could have only gotten wrenches in anyway. I do need to get under and check they are still tight.
So far I am happy that I installed Air Bags as I like the flexibility of them.
