Air Ride dually finally here!

[SnoKing]

Dang I can't get away with anything! Thanks for the correction. I guess I buy the next round!

That's OK, I did not notice that in the original photo either! SNOKING

Ok, boys & girls it looks like 175# in the tank most of the time. Dead, running, airing up. Really didn't seem to make any difference.
It did jump to 179# while airing up from "Transport mode" but, went right back to 175#. So using air tools (for a short period) should work.

Assuming the gauge is accurate!

 

[SnoKing]

Stab, is that a factory gauge or one you added? SNOKING

 

[Stab]

This is how I measured:

Next pic is "Transport Mode"

Last pic is "NRH mode"

Sooooo, it looks like about 5/8" ride height diff in a brand new truck.
But, I'm also finding that it will stay in "Transport Mode" until the speed of the doors locking on their own. (Aprox 15mph)
So, backing under your 5th wheel should be what some are asking.

A long bed mega cab would have a wheelbase of about 180" which brings to mind the old song that said "give me 40 acres and I'll turn this rig around."

That's a super duper Stabco Repower custom gauge that I got out of my el'cheapo freon recharge kit!

 

[Trowel2013]

Thanks Snoking, you answered for me. MCLB would be a awesome. My current truck is almost too long for modern parking spaces, so what's a few more inches.

 

[Stab]

So now that you have had the truck a week or so, what are your thoughts? Like trans? How's the power/responsiveness of the engine? Any dead pedal?
How's the uConnect system?

If they would make that truck in a long bed version..............I would be at the dealer ordering!

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.

 

[Brocky]

If the pressure shown (175#) is for the air ride system that sounds awfully HIGH!! All the Big trucks only run about 110 to 125 for everything: Braking and suspension, admittedly with a much larger volume capacity.

It's not about weight capacity, it's about room. Load your short bed(with a tool box) up with 15-8' scaffold boards, 10 scaffold bucks and 10 braces along with some adjustable feet and out riggers and close your tailgate so you can tow a trailer. Let me know how that works out. I use my truck for work and on occasion for family. A MC would be awesome for when we need it for family outings. A 8' bed is a must for my line of work. My previous truck was a 6.5' bed and it never had enough room.

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.

Good news!

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.



We ordered (Dealership) 1 with Air-assist 3500SRW it will be here Monday/Tuesday, I will take it home and demo it for awhile.

The air tank and the bags are separated by the regulator/compressor unit. They do not share the same air pressure. They connect via separate air lines to this unit. Because the air tank is fairly small the system probably keeps the PSI in the tank up so the bags can fill faster if needed.

 

[Trowel2013]

Just in case you didn't know this, if the tank is small there isn't a sufficient volume of air to run most air tools such as grinders or impact wrenches. It could possibly run a nail gun or something like that though.

Most pleasing, indeed! Can't wait to get mine.

Still 175PSI, Pac's little tank that runs their Brake (EB) and bags stops at 130PSI,all commercial systems stop at 120PSI that I know of. Its all guess work until the new system get's some time and use.

 

[Trowel2013]

I'm just stating that it doesn't matter if the tank holds 250lbs, it is a small tank in volume. If it could be adapted to run air tools, like suggested earlier in this thread, it will not run air tools that require large volumes of air. However, it's possible that it could run tools that don't require large volumes, if it could be adapted.

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.
