Body-roll with airbags?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

In a turn would the weight transfer force the bags on one side to compress and the bags on the other side to inflate therefore causing unwanted body-roll if the rear shared the same fill line and the front shared the same fill line?

I see it like a balloon, you squeeze one side the other side inflates.

Or am i looking too much into this?

Welcome to the forum 66TexasTruck.

Yes, that is correct. I have seen posts that disagree with this, but my personal experience has been that you do not want your bags connected side to side.

This will definitely produce more body roll.

While were on the subject of body roll. Today I was looking at rear shock placement on a bagged TF. The shocks I was using to find mounting points was a pair of air shocks that I removed when replacing with the bags. These were just for mock up. My question is, has anyone tried to use air shocks with air bags. Would hooking the passenger side bag with the pass side shock and driver bag with driver shock give a firmer ride? In a turn the body would roll slightly compressing the bag, forcing more air in the shock firming the ride and reducing the roll? Your opinions please.

So each bag should have its own dedicated air line to prevent this, right?

thats why most run 8 valves. thats, in my opinion the best, one fill valve and one dump valve per bag.

You "can" do it with 4 or 6, but that's not the best way to do it. Each corner should have a fill and dump valve to prevent air transfer.

Here is a diagram showing 6 and 8 valve set ups.
