    As I've been gathering parts to bag the Dodge, I ended up with 1/4, 3/8, and 1/2 inch air hose. I picked up 3 different lots of air suspension parts and haven't decided what size air lines to run. I have 8, 1/2 inch valves that are like new and want to run but I've noticed how violently vehicles with 1/2 inch lines go up and down. That cant be good. How limited are my options with out having to buy new valves? I'm on a tight budget.
    Thanks

    In industrial applications we restrict the flow rate to slow down the device. You could run the smaller lines with adapter fittings and that would slow down the delivery rate of air. You can also get adjustable flow regulators. For releasing pressure, when the air vents to atmosphere, you can get adjustable air mufflers to make the pressure bleed off slowly. Look around the http://www.parker.com site (industrial air and hydraulic supplier) or talk to your local supply house for industrial air/hydraulics.

  5. I like air ride, every thing looks better lowered, but you need to raise it up to drive it.

    Run 3/8 lines into your 1/2 valves. Yes they maybe too fast,but you run online slowdowns and slincers with slowdowns on the drop too. Ideally 3/8 valves would've been better,but use what you have or find a mini trucker that wants them.
     

  7. so 3/8 is best? why not use 1/4? too slow?

    1/4 will be too slow,and finding fitting that go from 1/2 not to 1/4 tube will be more expensive. The 1/2 fittings are about twice as much as 3/8 stuff. But you have them so use them. Get the push to lock type fittings in brass too.

    I'd use 1/4" line. The valves probably have 1/2" pipe thread. Just put bushings in to take it down to 1/4".
     


  11. why would you use the 1/4 instead of 3/8

    Why not use the 1/2in or 3/8in line and mount some manual ball valves before the fill valves and after the dump valve so u can dail it in to your personal taste.

    Once you set it, you can unbolt the handle so u won't have to worry about moving it or the handle being in the way

    ^^^all you want to know about bags can be answered using the search function.

    To the OP, a quick search on thread titles with the words (air bags) brought up 4 pages, this question was answered a half dozen times in the first page. Traditional or not, there is alot of info here on bags, doing a search will give you lots of answers.
     



  16. "thats a show rod not a traditional rod". they shut down that thread too.

    Easier to run 1/4" line. It takes up less room and will bend to a smaller radius without kinking. Bag systems on semi tractor trailers use 1/4 or 3/8 lines on bags that are 8" to 11" diameter.

    Run 3/8" lines. 1/4" lines will be too slow.

    As others have said, mount a ball valve before the inlet valve. For the dumps, install plugs with a small hole drilled in them. If it's too slow, drill the hole bigger.

    Thank you fellas, the manual ball valve seams easy to do and inexpensive. I think I've seen them at Lowe's. I went to a salvage yard today, and saw 1/4 inch air lines on modern vehicles. I've seen them work and I think they're too slow. I used the search function for the last two days, and didn't find the answer 'till now. So I appreciate all your input guys. I'm going from 1/2 to 3/8 inch line, which works out great cause I already have the fittings to do that. And manual ball valves for exhaust lines.

    How did your work? Did they fill and dump less violently than the straight 1/2 lines?

    The manual ball valves can work the same as flow regulators and air mufflers, right?

    just buy the right stuff made for the job, ball valves are for sprinklers...
    check out his link. it will have your lift slow downs and dump slow/silencers. i bet you'll have less money in the right shit, then buying adapters and such for the ball valves, and less fittings= less leaks.

    Mine don't dump violently at all, I'm just running 4 valves two for the front and two for rear one fill valve and one dump. But I am gonna go to two valves per corner eventually due to the fact it has a lot of body roll when cornering. Talked about doing just haven't done it yet as I am in the process of redoing the rear suspension on my car and getting it to set lower to the ground.

    I have two air ride vehicles, both run 3/8 valves and line with no issues. I slow down the dump by drilling a tiny hole in a brass plug inserted in the dump valve.

    They get shut down usually when the "air ride experts" get pissy.

    As for the question you can run 1/2 valves for volumn then next then down before the unit. This would also apply to air lines in someone's shop so if someone is reading and wanted to know how to plumb the shop there ya go.

    If you use small line, you will be buying adapters on both ends Bag side and valve side alot more chances for leaks, but the line is alot easier to work with.

    I bulid my own air mufflers by drilling a very small hole into a pipe plug, you can slow down ANY size line and valve combo. I have a full 1/2 set up on my 53 everything is 1/2 inch: bags, valves and line.

    you can regulate the pressure and slow the lift and reduce the size of the muffler hole to slow down the drop. I run 145psi in my system and yes its fast, but I can also run it at 120psi and its alot slower all with the same system and my drop is always slow.

    Just food for thought. and bags are traditional.
    Godspeed
