I'm running them on my f350 and can't tell any difference unloaded. I have tried several different pressures looking for a sweet spot for better ride. If there is one I have not found it. As far as loaded works like it should. Levels the truck. Well worth the money IMO.
I have the firestone air bags and the airlift 72000 wireless compressor on my 2011 F250. When unloaded you are suppose to run 5 PSI in the bags. When loaded you can go up to 100 PSI. I can't tell any difference when unloaded. I have heard nothing but good things of how they help when towing. I have a 29ft. bumper pull toy hauler and was getting some sag even with the weight distribution hitch. Thus why I installed the bags. Haven/t had the chance to tow with them yet but looking forward to it. The install is not too bad. A little tight on the driver side with the tanks on that side. I would recommend getting the wireless remote air as it really COOL....
I have the airbags on my 04 250. I tow a 37ft. 5th wheel. Really helps with leveling a heavy load. I keep about 5lbs of pressure in them when not towing and the ride is no different then before I put them on. I think they are a must when towing heavy loads.
Any Forum vendors sells them? I'm towing an 32 ' car hauler and using a equilizer hitch and still getting sag. How is the ride when towing a heavy load?
I mounted the compressor and tank to the outside frame rail on the passenger side of the truck. Worked well. Its tucked up and cant see it without crawling under the truck. Just another thought if your spare tire is in the way. From the tank to the inside controls I installed a "T" fitting and ran it to my fuel cap area. I installed a female air coupler between my fuel and def cap. Works well so now I also have outsource air for tires and such. Just an idea for you.
I installed my air lift. For you guys that have installed it, how often does your compressor kick on? Mine kicks on about every 10 min for a bout 1 to 2 seconds. I'm just wondering if I have to go spray some soapy water on the fittings.
Have not heard mine run since I installed it.. You have a leak. Just spray some soapy water on the fittings, you'll will find it. I had one when I installed mine at one of the T connections, just took it out, cut and reseated, did the trick....
how does it work with an air tank? will the compresser start up every time i start up the truck and fill up the tank, and then i use the switch and gague to determine what goes in the airbags?
You should have a switch to power your compressor so you can manually turn it off so if you have a leak, the compressor won't continue to cycle and burn itself out. I'm using upfitter/aux switch 4 to power my compressor. It fills my two three gallon tanks in about 2 minutes. Once those are filled, the compressor turns off but there's still power to the compressor as long as my upfitter is in the 'on' position. I have the Firestone kit and it comes with a gauge and switch. I can see how much air is in my bags and inflate/deflate accordingly. I'm pretty happy with it so far. Adding another gauge below my airbag PSI gauge so I can see how much air is in my tanks this weekend. This is mainly for my airhorn so I can ensure it's operating at maximum capacity/loudness. Also adding a couple quick connectors in each of the front wheel wells so I can air up my tires without having to drag a hose around.
A couple of pictures would be awesome!! Are your airbags on the same airline or are they separate? I have the gague and switch setup for both of them together, but i can get the dual setup if necessary. it would be alot easier to do them together...
Sorry for the wait. Here's the pictures. Hope you can make out where everything is and what I did. I put my filter underneath my Roll n Lock tonneau cover. The most common issue for compressor failure is water getting inside the compressor and rusting out the internals. I popped the airline through the pass through/rubber grommet that's in the bed. I've seen people mount their filters inside the cab. Apparently, there is a pass through under the rear seats when you fold down the seat. That's about as much as I know about that.
Filter
T-Connection/fitting
Driver's framerail. Ran my airline and power down it
Dual 3 gallon tanks and compressor mounted on some sheet metal above the rear axle
Bag PSI gauge mounted in cab
Air horn shenanigans. Have a switch on the underside of the steering column/kick panel with a switch to activate the airhorn. When it's in the "on" position and I honk my horn normally, the airhorn activates. When I have the switch turned "off" and I honk my horn, it's the factory horn.
I tied mine in together. There's a line going from each airbag into a T-fitting with hose going to the gauge/switch. This makes it so both airbags have the same pressure. I followed the instructions that came with my kit. You can probably download a copy off of Firestone's website. My friend who's a journeyman welder and has a welding skid on his truck tied his airbags in separately so he could run different pressures in order to level out his truck since there's a 1000+ pound diesel powered welder on one side and all of his wire/reels on the other.
That's ok for towing, but if you're hauling a heavy load in the bed it can be a problem. As the truck rocks side-to-side, the air goes from one bag to the other. So if it leans right, it squeezes the air to the left bag. So there's no real lateral support for the load. It's no big deal to just do it right the first time and separate the lines.
I manual fill mine. I put the valves on the bracket that holds the trailer electric receiver.
I was thinking about getting airbags on my 05 CC long bed dually but since most of you are saying it does nothing for the ride maybe I will just stick with the helper springs that came on the truck when I bought it. My truck has no sag at all when towing my 9k pound fifth wheel or when I put a pallet of stone or blocks in the bed. Towing rides like a Caddy, unloaded is good until you hit the back roads. Not complaining, its the nature of the beast but I would love to find something to tame the rear end from jumping all around.
