Best place to buy air bags?

AAA had the best price on Riderites when I did them on my Excursion, summer of '05. Are you gonna add an "infinite reservoir" air tank, so that you can ride around empty with them aired up? I'm sure happy that I did.

(on my rig they are collapsed when empty, and would get destroyed).

Not sure what you mean by the infinate reservoir?? I was not planning on having an air tank, but maybe you can convince me otherwise.

I just wrote a big long response and RME forgot that I was logged in and zapped it.

The air tank softens the effective spring rate of the airbags without lowering the capacity. Say you have the bags at 50psi. When you hit a bump, the volume of the bags decreases and the air compresses (spikes) from 50psi to 100psi (example) and doesn't wanna compress anymore. By adding a tank, the volume of the system is MUCH larger and the spike is less, say from 50psi to 55psi. There's a good write up by Bruce1954 at thedieselstop.com.

Run the small line from the valve to a big tee at the first airbag, then 1/2" line to a tee at the tank and then 1/2" line over to the other airbag. The tank is one of those 7 gallon deals at wallyworld for $20. I put the valve in the license plate hole in my rear bumper. Plenty of room for the tank underneath mine. RideRites have bigger fill holes so a 2nd hole isn't needed for adequate airflow.

Rides great. I keep it anywhere from 20 to 40 psi. Sits a little tail high, even when loaded. The bonus is that I didn't have to add rear blocks when I put the F350 V-code springs in the front of my Excursion.

I have airlifts and I'm happy with them.

I don't have an ""infinite reservoir" and they ride great, even when I have them up to 80 PSI with a heavy load. You'd have to really compress the bags to have them "spike" from 50 to 80 PSI. They're not designed for desert racing :)

Yup. PV=nRT :D

Generally speaking, if the bag is 4" tall, and you hit a bump that compresses it 2", you just spiked it from 50psi to 100psi. (assuming the bags don't expand horizontally...which they shouldn't)

Bottom line is that you're happy with it, and it sounds like you are. A nice ride at 80psi with a heavy load is what you are after, isn't it? How is the ride at 80psi with no load?
