mac springs bag 22inchs of lift

jsut read in the new sport truck mac springs ahs a bag that is triple bellow can collapse to 7 inchs and has 15 inchs of travel for a max height of 22inch hmmm that might be a good bag for the rear or would you be concerned of it collapsing under a load?

it still only equals out to 15" of lift, right?

Thats just the same bag as the 3b14. It has a collapsed height of 4.9'' and extends to 20.5''. Ive got a catalogue of over 150 airbags if anyone needs some specs on one.

oh damn and to think i thought i stubbled upon something new awe damn

I was gonna run actual double bellow semi truck bags but the frame rails on the box bodies are too narrow.

There are Semi Truck bags that are double bellow? Do you have any specs on them? That actually sounds like more fun than running the F2107 Firestones....

They make several different sizes. They look just like a firestone but are about 12" in diameter. They were too big around to fit between my frame rails the way that I wanted them to.

hmmmm, I think that might actually work for me. The F350's have a pretty wide frame from what I can tell.

Most semis are a single bellow design, and take forever to fill.

Alot of the Freightliners and alot of the dump trailers have the double bellow bags. They look like a really big firestone 2600#
