Air ride vs. Coils
Does any one have thoughts on how the ride is changed when going to air bag suspension? Is it rougher or smoother? can it be made firmer for better handling or softer for a cush ride by adjusting the pressure on the fly? I realize this would probably raise or lower the vehicle by doing so. Are slight increases in air pressure noticeable on the ride, in other words, would it force the vehicle way up on the ride height before you really noticed any ride firmness, or it would firm up a lot before the ride height changed much?

Re: Air ride vs. Coils
I had the same question, myself, about a month ago. I looked at all kinds of different suspensions. If you want to give the truck a lowered look, with large wheels - your best, in my opinion, is the air ride. Go with a quality air ride system and you should be very happy.

Re: Air ride vs. Coils
coils dont lose air and leave you layin frame in the middle of rush hour on the interstate

Re: Air ride vs. Coils
I've got bags on the back of the truck, but retained the coils up front. My reason was to keep the bed at the same height regardless of the load/trailer I was hauling. The ride is better, but the compromise is there's a little more roll in corners. You would not feel any appreciable difference in stiffness with slight pressure changes, basically, all you'll do is raise-lower your ride hieght.
I left the coils up front, and have over-load springs on the back for the very reason cdowns mentioned above....if you have a system failure your in a bad way, unless you build in stops or snubbers to prevent your ride from being immobilized. My rationale for using the bags was most of the over the road trucks are using them with success. Their purpose of course is a weight-saving measure, (bags are lighter than springs) and they're adjustable.

I'm so glad i'm getting some informed answers. I have zero experience with bags, and now I have 2 new thoughts to consider -weight savings, and failure posibilities.
How bout some more folks chime in. I would love to have multiple opinions and be able to weigh many pros and cons. I figured if I called a place that sells bags and ask questions all they are going to do is paint a rosy picture so I buy something from them. Still would love to have opinions on whether the ride might be firmer or softer. Thanks in advance, Drewski |

Re: Air ride vs. Coils
I have air ride and never had any issues or get stuck on the interstate. But sure its as much of a possibility as getting a flat.

Re: Air ride vs. Coils
I don't have anything bagged yet but have done lots of research and reading. My opinion is if you take your time and do every thing correctly they are very reliable. Yes there is always the chance of something wrong. Probably a little more than a static suspension. You can run dual compressors and add a schrader valve to the tank for alternatives if those fail.

Re: Air ride vs. Coils
Drewski, I had coils in the rear that came out completely. The trailing arms and panhard bar keep the third member lined up so there's no side loads on the bags, only compression.

Re: Air ride vs. Coils
I asked the salesman at Stylin Trucks this very same question. He said the benifit of bag's over coils is adjustabilty and softer ride. I like a firm ride and I do not like roll into corners. I also do not care about adjustability. So I am keeping the spring suspension. I now have DJM tube upper A arms and I will purchase DJM lower a arms and 2" drop springs. This will give a total of 5" drop in front. I will drop the rear 7" when complete.

Re: Air ride vs. Coils
you won't end up stranded laying frame on the freeway if you do it right, every semi on the freeway is running on bags and you don't hear of them blowing out too much. when you bag your truck you can build it to your desired ride height, increasing air pressure will make it stiffer and decresing will make it softer, of course either way is going to effect your ride height. use a sway bar and shocks with your bags and find the right pressure for the perfect ride quality and there's no way coils will compete with bags....just my .02.

Re: Air ride vs. Coils
oh, and if I put 100 PSI or more in my front bags it's almost like I replaced my coils with steel bars instead of bags, bags can ride way stiffer than coils or leafs if you add enough air pressure.

Re: Air ride vs. Coils
do you guys really think it's that easy to lay frame? It takes a lot more than just bags to lay frame.

Re: Air ride vs. Coils
It's not the frame I'd be concerned with. It would be the inner fenders laying on the tires and not being able to steer that would bother me.

Re: Air ride vs. Coils
that is possible, but if you're bagged you probably don't have inner fenders anyhow. I had to take my inner fenders out for my static drop before I bagged my truck.

Re: Air ride vs. Coils
definately, I can make my ride 100x better than stock or 100x worse than stock with the flip of a switch. but to be honest, once you're bagged you'll probably go more for the coolest stance over the best ride. I usually have my rear end too soft cuz I damn near drag my bumper everywhere, I do drag it when I hit bumps. I tend to keep the front in the sweet spot though.

Re: Air ride vs. Coils
from what I've read, if you plan to tow or haul with it you'll want your rear bags as far apart as possible and preferably behind the axle. I don't know that from experience as I'm bagged for the whole lowrider thing, but I've read that in more than one place.

2. Install the bag to designed proper "installed height" , then align the front end with bags sitting at proper "installed height"..you can fine tune your ride comfort with minor pressure adjustment. 3. For safety sake...if it's a driver, ALWAYS design your installation to insure your ride will roll, even with no air in the bags 4.Once you learn what pressure YOUR set up requires to inflate to proper installed height, you will find that 5 or 10 pounds either way makes a big difference in ride. When adding weight in the bed or towing a trailer, just add enough air as needed to maintain your bag's installed ride height 5. My experience with using any air lines larger than 1/4" & you'll loose your fine tuning capability. With 3/8" air lines & quality 3/8" Asco valves, any "bump" of the air valve switch will add or remove more than 7 pounds at a time, making it harder to find the "sweet spot" 6. And the best part is having the ability to raise your ride to get thru or over bumps & dips eg: parking entrances. It's a "no-brainer" (I'm sure this'll stir some debate)

Re: Air ride vs. Coils
also, your body roll will be a lot different depending on whether have have a front/back kit or a FBSS, basically whether you run 4 valves or 8. with both rear bags sharing an up and a down valve, it allows air to transfer back and forth between the two bags. that means when you turn corners the air will be forced from the outside bag to the inside bag allowing the body to roll a lot more than if each bag had it's own pair of valves.

Re: Air ride vs. Coils
My thoughts:
Pro's: Ride comfort. Adjustability. Con's: More complicated. More expensive. The design of the system is where you need to focus. If it's not setup up right, you won't be happy. Individual bag control is a must. A ride leveling system will also aid in the operation of your system once you have the bags installed where you want them. You must make sure you have clearance for the tires if air pressure is lost for any reason. I have both setups AND like both setups. My 68 SWB S/C truck has a static drop (6/5) and I enjoy it for what it is. My 69 Burb has bags with a ride leveling system and I exepect it to look cool (it doesn't lay frame but goes really low) and ride great, while still being able to pull a camper. Just my opinion, continue to do a lot of research, and I'm sure you'll figure it out, ![]()
