94 C3500; what towing bags for rear?

I have a 94 dually with a 2 link and just noticed that my bags are weathered and am going to need to replace them. Question is: What bags should I buy to keep most, if not all, of the towing capacity of a 1 ton and still keep a good ride? It is an over axle bag set up if that helps? I am new to this and dont want to make a costly error. Thanks!

I have some Chassis Tech 3800lb double stack bags on my dually over axle and it handles the weight good.....they get decent lift.....if you need big lift grab a set of triple stacks

I dont think I will need big lift (I say that now.. lol). I will check out those, thanks!! How do they ride? (Empty weight and towing weight)

They ride good.....about 15-20lbs in rear when i ride...when i hook up the trailer and put some weight on it have to bump it up to about 60-80psi depending on weight....rides better loaded than empty....and im running fairly stiff shocks which i would recommend

Just ordered this set...


with this gauge set up.



Plan is to eventually lose the AVS 7 switch controller and put switches in the center console and have the gauge sitting in the stock stereo location. I have no need to run the long AVS controller and would rather a clean look of the switches placed in an inconspicous location.

I want to have a slower air up, what parts should I be looking at to slow it down? At the moment the rear bounces up real fast! I prefer to have a little more control rather than going to full PSI with a quick blip of the switch. The front goes up slow-ish due to the weight but the rear bounces up real fast!

I'm running the 3800's on all corners. I have them on my 04 Dodge Cummins and my 99 Chevy 6.5 diesel. On the Cummins I typically run 75 psi in the front and 20 in the rear. If I have the trailer hooked up, even with 10K+ I never go over 40psi. On the Chevy I run 60psi up, front and 10 in the rear. I'm running Bilstiens off a 00 Escalade. The Dodge I ran 1/2" valves 8 total. But the rear was too fast up and slow down. The front was ok up but fast down. For the Chevy I ran 3/8" valves but I ran 2 for up and 2 for down and the front lifts nice and drops nice. The rear I did different this time. I did 1 for up and 2 for down with each down valve close to the bag so there is less line to purge the air. So a total of 7 valves. It is pretty even on drop. The lift is not fast like it is on the Dodge. So I don't have to bump the switches like the Dodge because it is nowhere near as sensitive.

Thank you for taking the time to respond and explain your set ups!!

So if I understand this correctly, you are running the two rear bags into a T then to one valve to raise both at the same time? They fill up at the same time and the PSI is combined for the total of the two bags as opposed to one bag per gauge?

Yes, I'm not worried about having four corner control.
But for stability the fronts need to be seperate. Putting a "T" for the rear makes for a simple control. It is a suggested method on big trucks that come from the factory. By having the rear "T"d together,if a bag loses pressure you still have control. If you would run 4 corner and a front bag goes down the vehicle tends to take the load off the vehicle diagonally. It will make it a little scary if turning and a bag goes down. Most buses that have handicapp access has 4 corner so it can drop a side for easy access for wheel chairs. Or big dump trucks that can play with weight transfer. On these little trucks in comparison it isn't a problem.

My truck looks like I am into the FBSS thing but really, I just like lowered trucks on bags since they are still able to be used and look good at the same time. So I guess once I get these new bags in I can look at the set up in more detail and get the rear on one switch and keep the front two on seperate switches.

I was thinking about your setup and mine... you say you put 3/8" on the rear but I think we have the same bags... mine are 1/2"... did you put a reducer on the line going into the bags?

Sorry for the elementary questions, this is a whole new world for me and I want to get this truck right the first time so I am not messing things up and having to spend more money. This was suppose to be a minor fixer upper but already looking at about a grand just to get it semi right and safe. Thanks again for all you help!!

Yes they are the same bags I use (Airbaggit 3800's). Sometimes they come with 1/2 holes even though they are listed as 1/2 they can come with 3/8 holes. either way a simple reducer will work. Usually Airbaggit sends the reducers with the bags.
