I have rear set of air bags and i ran fill hose to back bumper. So i fill each bag separetly and use a air gauge/chuck to fill each side. I really like and use them. would like to upgrade so i have in cab fill button and compressor on/off. Looked at viair stuff. Also when i do load truck it really feels tippy or rolls weird. Is that your experience. I was thinking of in-bed camper and what that would be like. Anyone with aftermarket sway bars on rear?

 

Thats funny, mine seemed to make mine more stable, I do have bilstein shocks, but I doubt that would stop side roll. How about your tires are they e-rated, aired up, just things I check, I just air mine up at the back bumper, something I read also is make sure if you install a pump that they do each airbag separately, not both on one line as the air will shift from one side to the other, good luck

 

I would look into the airlift wireless kit.

I have an OBA setup with a Viair 400C and just fill my bags like you do now. I would like to eventually get the Airlift kit.

 

I installed the air lif in-cab control, it is really nice to have, makes it SO easy to adjust the pressure. You would probably solve the 'tippy' or 'roll' feeling with a rear sway bar, they def make the srw truck feel more planted.

I never understood how SRW vs DRW effects sway that is cured by a sway bar. Swaybars fixes sway from the suspension, that has nothing to do with the number of rear tires.

 

My truck was originally a srw, I swapped a fellow who wanted to go srw. I had a sway bar on my srw, and YES, it does fix stuff from the suspension, or at least it did from my experience with the srw. When I did the srw-> drw swap, I took off my rear sway bar to see how the drw 'felt' as compared to the srw, and that 'tippy' or 'roll' sensation returned. While the number of tires on the ground does stabalize the truck as far as what I would call 'road grab' and the benefit to the drw is all about load distribution, the rear sway bar seems to 'adjust' the suspension movements front to back, and corner to corner . . I hope I am making sense with this explination . . I am going to put my Helwig rear sway bar back on my truck.

I am not saying they don't work, just pointing out that the kind of sway they eliminate is immaterial of SRW vs DRW, as you pointed out with the return of your roll sensation.

 

here is a cheaper option, I had this on my 01, and will instal it on my 03 shortly
I mounted a air tank(40$) from a transport truck and used the incab mechanical controls (60 or 70$) and once the tank is filled up to 120 -140, it allows multiple up/down before it needs to be filled again, I also added a quick disconnect so I could plug in my hose and air chuck, which allows me to fill up tires if needed.
I used to haul freight daily for a living and even with this set up I did not need to fill the tank very often

I went this route because at the time air compressor set ups were expensive and I just could not justify the expense

 

You can do onboard air on the cheap if you plan the system out.

A 2 gallon tank, and a small 33% duty rated compressor (Viair, Air Zenith, Oasis) is really where your costs come from. 1/4 inch air line (the red stuff) can be had from Les Schwab's or other automotive stores, and the fittings from Home Depot or Lowe's if they didn't come with the air line kit. A pressure gauge, manual override power cut off switch, 90-110 psi switch and a dump valve (drains water from the tank) will finish it out.

I have Firestone airbags and in-cab controller with compressor on board. I added a small air tank to it. With this I control my air bags and my Rancho 9000s. I also added a connection to pump up tires if needed. This works very well for me.

I also have a Hellwig sway bar. This helps to reduce sway, just as designed. I carry a large (for a SRW) cab-over camper and this set-up works well.

The "tippy" or "weird" roll may be caused by too much pressure in the air-bags. Even with a heavy camper in the bed, I run the air-bags at 40-60psi (I also have Hellwig helper springs).

beewize, you'll really like being able to adjust the air bag pressure while rolling down the road, as road conditions change you can add or subtract air for the best ride.
FB maybe right, by having too much air in the bags your not getting the stability of the leaf springs to control tippy/roll?

 

That's what I installed, works great for me.
Since it's wireless, there are no lines to run to the cab, so install was super easy.
It's also digital, so it has memory settings and will maintain any PSI you set, automatically.

Here's a link, you can get them for much less than MSRP if you google prices for it.

I absolutely hate my wireless system. Miss the old tried and true inboard controller. Compressor runs off and on all the time due to screwy logic of the controller and many times it looses signal and then your just plain screwed. I'll make you a deal on mine....:-)

Oh..and I've had several conversations about the drsign with airlift and they admit there is a logic problem with their design.

 

AirLift part numbers 73001 and 73003, if you already have air bags and OBA or are going to build your own OBA kit.

Buy the parts direct from AirLift as they're cheaper than Summit Racing or Jeg's by at least $100.
