Air Lines

Where is the best place to come out of the front crossmember with the air lines? One down each side or both down one side to the valves? Will be using 1/4 in lines to a Big Red valve set up on the frame on the drivers side any help or ideas will be great...thanks in advance

Re: Air Lines

Where are you mounting the valves? Are these 1/4" or 3/8" Big Red valves?

Re: Air Lines

1/4 inch Big Red valves mounted on the frame most likely on the driver's side. Unless there is a better location. Tank will be mounted close to valves as will the compressor..thanks

Re: Air Lines

You can run both front lines down the drivers side and cross over to the right side inside the front crossmember,... to get to the passenger side bag.
I drilled a hole under my motor mount stand (from the bottom) and used a rubber grommet to protect the airline.
Use plenty of wire ties to keep the air line away from exhaust heat and from getting pinched.

Re: Air Lines

If you don't have your fitting already, I would consider running 3/8" fittings and lines. The 1/4" Big Red is a bit slow and the 3/8" line will help speed it up.

Re: Air Lines

Thanks N2TRUX i do have 1/4 in fittings, but i can change them i've read post on this board that 1/4 in would make the system more manageable...would 3/8s be better? Not too fast? I have a Thomas 327 compressor and i will be getting a 3 gallon tank to support the system, i'm not looking to be speedy up and down. I just want the available adjustment and recovery. Thanks for your input.

Re: Air Lines

I just went from a manual 1/4inch valve setup with 3/8 line to a full 3/8 electric valve and line setup. I also went from 3 gal to 10 gal tank. The increase in valve size/lose of line due to swithing from manual to electric and they are way to fast. tank at 100 psi and the front bags jump 7-8 psi every tap of the switch. before it seemed really slow, I now see slower is better than to fast. I am purchasing some speed reducers for the dump sides that way I can air it up past the ride height and lower it to the correct pressure without fussing to much with the switches. maybe this info will help with your line and fitting sizing.

Re: Air Lines

Dont mean to hi jack this thread, but I have 1/2 inch xtreme valves (I think) or I know for sure that what I bought was for 1/2 setup (lines,fittings, and so). My question is that im really not trying to hop the truck but want to have good control of ride height but dont want something slow either. What do you guys reccommend? Lines? Valves?

Re: Air Lines

Having had both 1/4" and 3/8" I would say the 3/8" is the better of the two. Yes it is fast, but not crazy fast. I think you would be happier trying to slow down a slightly fast sysptem than you would with a known slow system.

You can always insert a piece of 1/4" line inside the 3/8" line to reduce the speed.

Since you already have the 1/2" system I would go with it. You can add restrictors to slow it down of needed.

Re: Air Lines

I agree. with the old setup I couldn't get any faster without upgrading. with the new one I can alway slow it down.

C10slim add some speed reducers to your system on the intake and dump side during install and that way if it's to fast you can just tune it to your speed. From now on with my installs they are going in just incase.

Re: Air Lines

you can get them at most air suspension websites. suicidedoors,avs,airbagit all carry them. This inline lift side are installed between the valve and bag and you adjust it with a thumb screw. I am acctualy going to get compressor drain valves from lowes for my dump side they work the same way and cost 5 to 6 bucks each. for you the big red valves I belive you will only need one for the lift. just put it between the valve block and tank.

Re: Air Lines

I prefer the up fast, down slower. It's easier to slow your set up down with bigger valves & lines than it is to speed it up with smaller valves & lines if it's to slow, you can buy speed reducers for dumps & lift valves. I'm gonna be running HE8s with dual 3/4" lines & four 3/4" Parker valves for the lift & two 1/2" Parker valves with speed reducers for dumps up front, gonna make one set of the 3/4" valves switchable so I don't run all four all the time. Out back will be RE8s & all 1/2" lines & valves with speed reducers for dumps.

Re: Air Lines

Thanks again all. Where do you guys run your airlines where do you enter the front crossmember. i need to drill 2 holes and i only want to do it once. Inside the frame rails, directly under the rails or on the outside of the frame valves are assembled together so i'll be running all the lines to one point

Re: Air Lines

I'm not sure where mine will be routed outta the bags, yet since I'm runnin dual 3/4" lines. I'll probably run'em out the back of the engine crossmember using rigid stainless tubing & bend with a tubing bender towards the rear on the inside of the frame cause they will be close to the exhaust. I'm gonna try to mount the valves inside the crossmember.
