Air Ride dually finally here!

[Stab]

If you want to burn up the pump in a hurry go ahead and use the tank for something other than the bags. The system is charged with nitrogen from the factory and nitrogen is used to refill during any service. The system is made to transfer air from the tank to the bags and bags to the tank. The pump is used for the transfer, it's designed as a sealed system. The system can make up for very small loss of air, but loss of significant volume will result in overheat of the pump and system shut down.
If you want to try it out, just change the height up and down a few times and it should give you the overheat warning.

Now that's interesting...... I've cycled this system 7-8-9 times back and forth trying to find what it's doing and it just keeps up no problem. No over heat warning of any kind.

Please inlighten us on where that information is. I'm about ready to air chuck this thing and would like to know.

That gauge cannot be correct 175LBS the bags would be rock hard... ( unless check valve somewhere) 135 psi would max out just about any air suspension. I have the 4 point Ram system in My 1500s (2014) and they have never been over 50psi even on off road 2 or transport mode. Heck I run the Riderite at 15 to 20 Psi.(2013 & 2014 Ram 3500s) if you run over 20PSI empty it will ride like a horse wagon. I would be more concerned about the body roll with the Air-assist then ride, If you have EVER experience that rocking in and Air ride system you will know what I'm talking about. Body roll is the reason (MAIN) ALL commercial Air systems are Cam designed. Yes ,Navistar and Freightliner had spring over-air, but it was still cam design and 4 point weight distribution. The real question Beside body roll, can the New spring design handle the weight distribution equal to Spring (Leaf) or Cam designed air, if it does I will buy it.

If you go form entry/exit to off road 2, 5 or more times In my 1500s the EVIC will give the operator a time out heeheee.

We'll Stab.... I give another heads up, You know that 1 piece drive shaft Aluminum (2015) We had 3 broken this winter alone and when I checked North America 75 national Back order , the real sad part is 1 that broke ,took out the DEF harness that's on national backorder, Some had the incorrect pin-outs (replacement's) witch created new problems and more delays. So before you temper with the system relax a little. Even adding any add-ons could cost $1000s in repairs.

awesome! I have some plans for this system. If you run the air pressure in the tank down low when does the compressor kick on? The ignition needs to be on correct?
Does it react quickly and refill the tank? There was another post on another forum...the guy claimed he had to toggle the system in/out of transport mode to get it to refill the tank. That sounded odd- and I was worried it would jeopardize my plans.

My plans: I want to add a second tank so more air is on board for filling tires....etc... I also have an air ride fifth wheel hitch, so I plan to use this air to fill my hitch when needed.

It started (the compressor) and shut off in less than 10 seconds. The tank NEVER saw less than 173#. I didn't "toggle" the system. It just did what I told it time after time.
I didn't run the system down other than going from "Transport mode" to "Normal Ride Height mode" several times. The ignition system needs to be on.

Now I'm waiting for verification on the nitrogen in a closed system before I air chuck it. Or add to it as you suggest.

Interesting on the pressure, it does seem high.

I recall reading that the air suspension was a closed loop system, is that not the case? Or how did you add a gauge and not mess with the factory fill?


jfcody, have you ever used an oba setup with a tank and small compressor for tires? I have and won't have a tank again. Tires at 80 psi take too much air to make it worthwile. You end up filling the tank and the tires at the same time and it takes longer.

Oh, I'm plenty relaxed waiting on this truck for a year.....So the replacement wiring for the DEF harness is some how intrigated in the air ride system? That 8" aluminum drive shaft reduced to 6" before the rear axle is hard to ignore! How did they break them?

The presure is in the tank, not the bags! I just snaped the gauge on the quick release fitting. I didn't even hear any air escape.

 

[AH64ID]

Gotcha, I didn't realize the hose was OEM... I thought you added it.

The pressure does seem appropriate for a closed system then. I would expect it to be lower id it was open.

Am I to assume I can run my air horns????

I heard that!

 

[AH64ID]

I don't think so.

But I am not sure it was a serious question

 

[Cummins12V98]

OK If he installed a air gage then there is air there. Why can't you run the air to a solenoid for the air horn then to the horn????

It's a closed system, supposedly, so there isn't a way to refill the tank if you let the nitrogen escape thru horn.

In a closed system the pump fills the the tank from the bags, not the atmosphere.

Unfortunately this all makes sense- that it is a closed system. The lack of a moisture drain cock on the tank (or anywhere on the system) is a tell tale, in addition to the high pressure in the tank.
I was hoping it had an air dryer in the compressor, but that is not sounding likely. Too bad...this is a negative in my book once again for this system.

agree- unless it is a large compressor with more output - CFM

Even the biggest of 12v compressors are too small, IMHO.

Then again I often need to air up 2-4 tires. If I only planned on flat repair a small compressor and a 5 gallon tank with a manual valve wouldn't be too bad (I've had that setup).

But in terms of space and use I am quite happy with my Viair 450C and no tank... And it gets a bit of use.

air ride or straight spings

So I am awaiting an air ride 3500 SRW to hit the local dealer to drive back to back with straight spring version as I want the aisin so I need to go 3500. If anyone has done this comparison already can you all write in and tell us what your experience was.

We build & buy trucks for TOWING, not so much HAULING. So in the twenty five years we've been towing with a short bed Dodge Diesel of all cab sizes, there only been one time that I wish we had a long bed instead of a short bed. That's when we were hauling five dirt bikes to one side of Moab UT to the other, leaving the toy hauler set up.

Just my opinion but, you can't load a long or short bed to it's limits anyway. And we've tried!! So in order to utilize the power of these trucks a trailer of some kind is a must.

Except for those of us with truck campers.

What kind of limits? Volume? Weight?
