I like a small compressor and storage tank on board for adjust-ability on the trail. It also comes in handy for tire inflation.

FIREBUG,DO YOU HAVE TO HAVE THE TANK OR CAN YOU HOOK THE COMPRESSOR DIRECTLY TO THE BAGS AND USE A SWITCH TO ADD AIR AND A VALVE TO DUMP

i was thinking 1 of those small and light 12volt compressors would be ideal

either way you need to go through switches so you can air the bags individually,,,or use a hose. The tank just stores air so it is much quicker,,,it also stores enough air to blow up tires when they break the bead.

So we are all clear, nothing but a shrader valve is needed on the bag to fill it up. If you desire to fancy it up, all good.
The bags should be isolated from each other so they work independently.
This is the bag I installed on JIm's car and the "free" set goes on my SS2.
#3800
Double Convolute
Air Spring
Diameter 8.50"
Closed 2.8"
Extended 12.50"
5,000lbs per bag
400psi rated
$89
Simple rules to follow on installation,
Use largest bag you can fit into the suspension. Bigger the bag the less air it takes to maintain your ride height and the softer the ride. If for some reason you install too big of a bag it can be made smaller by adding antifreeze into the bag. Adding liquid reduces the volume of the bag raising the spring rate. Should you install too small of a bag it can be made larger, to an extent, by adding a tank to each bag increasing it's volume which decreases the spring rate.
With the arms, cv's and axles in place raise the arms to max cv angle, and with the bag almost collapsed you now have an idea on where the top of the bag needs to live. The best result would be that in that max up posisition the bag should be directly on top of the arm.
The bags are very forgiving. They can be mounted where the top and bottom plates can be as far as 2" off center from each other and as much as 30 deg out of alignment. As long as they are protected from abrasion, they won't break. I have only seen 1 air bag explode on a tractor trailer. It was a 15 year old bag on a heavy haul trailer that had 120,000 lbs on deck. And it did go bang, big time. Differance for us is it had 120 psi in it, ours will only have 40 or 50 psi so no problems.
Using the hinge set up on the arm makes the bag and arm work togeather so sweet, no gross bag mis- alignment anywhere in the travel.
The bag should be mounted on the arm about 1/3 the way down, or further, from the inboard pivot. With the arm as far down as the cv angle will allow, inflate the bag and see where it will fit, the parts will show you where they need to live.
