Air Bags For Towing

Air Bags For Towing
About a year ago I swapped in some chevy 63" springs and took out the overload and one other leaf (was WAY to stiff with them in for every day driving) and rides like a dream and holds its own flexing, but lacks in the towing department. I tow/haul on a semi-regular basis, maybe about once a month, and the rear just squats like nobodys business to the point my rear tires rub when I hit bumps. What are your guy's thoughts on air bags for towing? are there any avaliable for lifted trucks? is there a way to make them work with flexing like only mounting the top or bottom side? I would most likely only have pressure in them when i tow and leave them at 0 psi the rest of the time.

I would love them if someone came up with a quick disco setup.
Technically the truck should not be lifted by the frame with them on as some manufacturers are afraid it will pull the bags apart if you let the suspension fully extend.
I have never used airbags on my trucks for that reason though, so I'm not speaking from experience.
And as Zach said, they should have 5-10psi in them all the time.

I have them on my truck with 4" of suspension lift and have no troubles, but mine is by no means set up for flex. I have installed them on my buddies F150 with 6" of lift and his definitely don't fully extend. They are great to have for occasional towing because you can quickly and easy change the load characteristics.

this sounds like a good. i am a truck and coach apprentice and airbags have been proven to be the best for towing (if set up properly) because they always maintain a constant ride height and very good ride comfort. they are also eaily removable. if you run synflex line like used on trucks instead of a rubber line you can use quick connect push style fittings that allow you to remove the line in about a second. then most bags are only two or three bolts to pull out.

I still don't see why a person couldn't hard mount the top of the airbag to the frame, and put an upside down "cup" sort of on the bottom of the airbag, facing down. That "cup" would rest on top of a hard poly bumpstop on the top of the axle. This would help support weight like an air bag typically would, but allow the axle to droop well below.
Maybe I am missing something though, I've never had them but always thought it would work well for a multi-purpose truck.

But again it would depend on the airbag and everything too, I don't know how rigid they are side to side. I don't know if they would fold under weight without being firmly bolted on both sides. I thought about buying some cheap used bags at one point but I don't have any way to fab something up anyway..

How about limit straps holding a base that the bag is mounted to? So it acts like an external bumpstop kinda thingy. So if you flex down the bag will extend untill the limit straps are tight and the axle can move farther. I would think that some teflon strips under the mount and a flat surface on top of the axle will have to exist.
Requires some more fab work but will work sweet i think.
Or just go buy some air shocks...

That 91 is lifted in my picture and its mounted the normal way just with a body lift spacer under the bottom air bag mount so it wont over extend, Firestone air ride bags are great, next choice would be air lift which is what i'm getting this week because i could get it cheap from work.

have any closer pics of that bag set up?
ok, I have just never seen air shocks used in conjunction with anything else. can they be filled with air or does it have to be co2 or something of that sort? basically i want to know if i could hook it up to my on board air and just have a switch and guage in the cab to control the pressure with. If regular "humid" air can work and these type of shocks aren't super spendy this may be the route I go since i am looking to replace the rear shocks anyways. are you thinking like the fox style air shocks popular with rock crawlers or something else?

I'm not sure I would run air shocks as a supplement to leaf springs. I think they do fade, and are designed to be used as stand-alone spring/shock, and I'm not sure they will dampen the leafs properly. Plus if they are carrying a lot of weight you'll need to build stronger shock mounts. I think they are charged with nitrogen..?
But I don't really know for sure. If I were you and I could cut/weld/fab stuff I would just buy a set of airbags, and see what you can put together for some disconnect mounts.
