Need airbag suspension info
 

I'm looking for any info I can get. Pics are a big plus. I have a truck i'm working on now and I want to bag it, but its hard to find info, I want to make my own setup, but I can't find info on spring rate of airbags. what brand are people using and what size. Also, what pressure are people running when going down the road and how long are the bags when at ride height.

Re: Need airbag suspension info
 

It's only a matter of looking for it. This forum has TONS of posts on the subject, all you have to do is read them.

Lets start with what year truck, coil or leaf, and how low you want to go.What is your budget, and do you plan to cut the fenders, bed, etc?

Re: Need airbag suspension info
 

I recommend taking a quick visit to the suspension section of this forum. Plus do a search there are more then plenty of bagged set-ups thats are posted on here...

edit: I just realized i was already in the suspension section LOL.... but I will say I do most of my installs with the dominator bags. I really like'em I was using slams but the bit of savings I get and still good quality i think its win-win. If you do get the slams you want a 7" bag in the dominator is the 2600lbs. But like N2Trucks said we need more info on your particular ride...

Re: Need airbag suspension info
 

I've seached on this forum, but there is not alot of detail to the setups, there are some good pics of the whole truck lowered, but no info. I have a 1970 C-10 longbed, I don't want to notch the frame, cut the fenders/bed or anything like that, its a budget build, so I just want a simple setup, something that will ride at stock height but I can drop it down to the suspension stops. Also ShowSS12 said " 7" bag the dominator is the 2600lbs" this is the type of info I can find on other posts, don't get me wrong,I do appreciat this info, but its vague, I assume its 7" diameter and 2600 lbs is its max capacity, but what is its spring rate and at what psi.? They only tell you the max psi. and how tall is the bag at ride height? I don't just want to buy some bags and plates, weld it in wherever looks good and just drive it, I want to engineer a system and do it right the first time. Its funny how I read through other peoples "builds" and they start out with an airbag system that looks good, but a few months into the build, there setup is totally different. I know i'm coming off as a bit of a jerk, thats not how I am, I just want some good info, not someone telling me to look harded, if you have some info, just lay it on me. Thanks.

Re: Need airbag suspension info
 

look at slam bags they have all their info on the website

Re: Need airbag suspension info
 

This is the info from ***************** on the dominator 2600 "The latest and greatest from AirLift Company! Design height range from 6.0 to 9.0" with a 9.7" usable stroke. Maximum pressure of 600 PSI. 1/2" port." This ifno doesn't really help.

Re: Need airbag suspension info
 

This does look like a noce bag for $60

Re: Need airbag suspension info
 

why not just go buy a slam bag for 100$ and be done with it,
also are you wanting to build your truck to do roadcourse or autocross with? if not you should just fit the largest bag you can and then buy a good shock

Re: Need airbag suspension info
 

check out my build it all there..I used ALL STOCK suspention parts except the bags....

front I run about 50 psi rear 35 psi

Re: Need airbag suspension info
 

If you decide to go with the dominator bags check ebay they have them on them on there 4 bags for 175shipped

Re: Need airbag suspension info
 

thats a start, I thought the psi would be much higher than 50/35, now I have some idea, thanks, and those Ebay bags, hell yeah! My truck is going to be a daily driver that I will use to haul my boat and a trailer only a couple times a month, so I don't need a big fancy setup. now how about the air lines, I just want a front/back setup, do I still need 2valves per bag (up/down) or can I just use 1 pair for front and 1 pair for the rear?

Re: Need airbag suspension info
 

You really need atleast 6 so when you turn corners the air dont transfer and cause body roll

Re: Need airbag suspension info
 

http://cgi.ebay.com/ebaymotors/Domin...ts_Accessories THIS KIT IS FROM THE SAME SELLER FOR A REALLY GOOD DEAL YOULL WANT TWO MORE VALVES

Re: Need airbag suspension info
 

I wouldn't consider anything other than an eight valve system and I'd definitely notch the frame.If you have a welder (you didn't mention) and a bit of pipe and plate then it won't cost much at all and you can take full advantage of the low end of the system.I could be wrong,but I don't think you'll find much info on the spring rates as they are changing as pressure changes.Set them where you like it,get it aligned at that pressure and drive.My bags have a recommended inflated height of 7" and I'd imagine the others have their recommended heights as well.Why wouldn't you phone PB or SD or one of the others and ask some questions?These are the guys that do this day in and day out.They will have the info you want.

Re: Need airbag suspension info
 

Rollie if he had read and followed my build he would be on air for cheap!! its all there and I'm happy to help .......hell I pout the 472 in my truck 9 days ago and have over 500 miles on it and I'm leaving today for at least another 150 so I guess I would comsider my truck a DD...but I will say the Pro Streets are getting pretty bald..they don't wear well

Re: Need airbag suspension info
 

I have a welder and tourch at home, and I'm a painter/powder coater at a metal fab shop and I can get any supplies I need and help if I cant do something so notching the frame would be no prob., I just didn't want to cut a hole in the bed to make room, I like the setup Hottrucks has, he can still use the bed for haulin

Re: Need airbag suspension info
 

So 8 valves is a must, each bag has to be isolated from the rest so they dont transfer air from one to the other while making a turn, this would increase body roll, correct?

Re: Need airbag suspension info
 

Correct. Independent control of each corner limits air transfer and/or body roll.

Re: Need airbag suspension info
 

I think I would definitely notch the frame if I was you then.The pumpkin on mine stuck through the floor about 3/4" when I did mine.I was like you and didn't want a hole in the bed so I raised the floor.If you don't want to go to that much trouble,you could always put in some bumpstops that would limit the travel while still getting as low as possible and not having to worry so about the axle bottoming out on the frame while driving.Just another idea.

Re: Need airbag suspension info
 

I'm gonna check out your build thread later on....sounds interesting.

Re: Need airbag suspension info
 

measure fifty times never cut????....2 1/2" is the most you can go and the rear will be tight to the bed.....and flip your shock mounts

Re: Need airbag suspension info
 

Dude, statements like this can confuse the heck out of people w/limited knowledge & are asking questions.

Re: Need airbag suspension info
 

Here is some info I found, the larger the diameter of the bag, the less PSI it will take to raise the vehicle the same height as a smaller diameter bag,and this should give a softer ride.

Re: Need airbag suspension info
 

I just installed 4 2600 dom bags and manual paddal valves. Man those are smooth. All I want is to go up and down. It takes me 10 sec to get to ride hight. I made a mainfold fed by 1/2" line then breaks down to 1/4" to the switches then 3/8 to the bags.

Re: Need airbag suspension info
 

Keep in mind, the 'less' air (softer spring) is not always the better ride.

I had 7"/2600# bags mounted where OE rear coils go @ 30psi & had a very bouncy ride. If I bumped pressure over 35psi, the ride improved but now the height was more than desired. So in that case, a smaller diameter bag requiring slightly higher air pressure to achieve the same overall height would have a better ride even though it has higher pressure.

Re: Need airbag suspension info
 

Hey jjjmm56, thanks for the pics, looks like a nice basic setup, do you have a sketch of how its plumbed? Also, where did you buy that manifold and switches?

Re: Need airbag suspension info
 

I was doing a websearch on something totally off topic of air suspensions when I found this link, Its a good air ride build http://67-72chevytrucks.com/vboard/s...d.php?t=377272

Re: Need airbag suspension info
 

that's my build. I have Dominator 2600's on my truck and I've been very happy with them. if you need any info outside of the build thread, get back to me.

Re: Need airbag suspension info
 

The switches and guages you can get from AVS. I got mine from a local shop. Paid about 150.00. Much cheaper than electric setups. The mainfold I made. As for the plumbing, the mainfold is fed by a 1/2 line to the bottom ,that feeds the 2 double 1/4 lines that supply air to the switches. There is a post on manual valves with pics. You may need to search for it. I"ll take some pics of the bottom of the mainfold this week
