Finaly gather all the parts.
 

Quick back story. I bought an "06 Tahoe a few months ago. With the 30 day tags still on(goal was to finish before they came off) I decranked the front. To drop the rear I had some parts to replace the rear coil springs with bags.

Money and issues of trying to make a air bag directly replace the coil spring has gotten me to today. It has look rather goofy since with large rake.

I have finaly almost 4 months later rounded up all the parts! The valve has a dump feature so that if I want to drive under a trailer I can dump the air and fit under it easily. Then let the truck air back up and hitch it's self. The tank is 1 gallon.

It will not work out like I was planning. I will cut the ridge for the coil spring off the axle mount and weld a plate with a bolt for the bottom. On the top I will build a bag mount out of 1/4 plate. I am very dissapointed that I will not be able to make an "air coil spring." But how often do things turn out like your original plan?

Please don't let this spiral out of controll.

Dude...you WILL get flamed for this. Why do you even try?

Ppl take you for what you have been in the past and its really hard to change that...especially when you post retarded threads constantly. I just saw the op under the thread title and thought to myself oh lord not again. Idk why I even opened it, its not like the project thread youre gonna post is gonna be helpful to anyone, so im done

Why not just use CoolRide components from Air Ride Tech?

wtf is a "air coil spring"?

Thank you. I am going to build my bag cups just like the cool ride ones. They are a direct replacement for the coil spring just like I was wanting to do. I will have to go monday and get some 2" OD tube, because, that is how they locate the cup on the inside of the coil spring lip.

I am glad you brought this up my buddy was looking at the Steve Mead Tahoe but it wasn't giving detailed info about the cup set up, turns out he installed the coolride air springs. It is simply pull the coils and install the bags.

Are you still planning on welding those things to the thin sheet metal of that body??

No I don't need to weld anything to the truck. That was they plan of making the bag a direct replacement. Therfore if I ever want to go back to coil spings I can do so.

The smaller tube fits into the cone that locates the coil spring and the outer pipe holds the weight on the factory perch.

And PS,

1.I don't know why some people "waist" their time either
2.it's been proven in the past that you don't and or can't take advise..
3.you're not building it like anyone else would....

;)

How do you plan on airing them back up once that magical dump valve does it's job? That 1gal tank won't be enough to take those two bags from empty to holding up the ass of a Tahoe... Definitely not with a trailer on it... But I'm sure you have some magical math in custm2500 world that says otherwise....

And lastly, you plan on letting your family ride in this thing farther than the end of the driveway?? What's going to happen when you're riding down the highway, you have an air line start leaking and next thing you know the tires are rubbing the fenderwells with no way to pick it back up? Then your late for supper because your "engineering" has eff'd you... :jest:

It isn't a a magical dump valve. It is used on semi trucks all day every day, for the same purpose. So that they can get under a trailer if it is a few inches too low.

The tank doesn't empty if you dump the valve just the bags, therefore wile it may take a full tank and 30 seconds to a minute of the pump running to make it to ride height but it takes much longer to get the trailer hitched up.

Here is part of the directions. Just in case you think I am making all this semi truck stuff up.

The Ridewell Height Control Valve (HCV) is a mechanical device that
automatically adds to, or exhausts, air from the air suspension when changes in
vehicle load are detected. The HCV will respond to dynamic changes, but does
so by limiting air consumption for small changes in suspension height.
· The HCV is available in three configurations:
1. Non-dump (Figure 1).
2. Pressure dump (normally open). Pilot pressure (75 psi minimum) is
required to exhaust the suspension air springs (Figure 2).
3. Zero-pressure dump (normally closed). Removing pilot pressure exhausts
the suspension air springs (Figure 2). If connected to the emergency air
source (red line), the HCV will automatically dump when the red line is
exhausted.· HCV ports use push-to-connect (PTC) fittings for 3/8” tubing.
· Dual HCV mounting is allowed. The vehicle OEM should be consulted if
converting from a single to a dual HCV configuration.
· Various HCV and linkage kits are available. Contact Ridewell or the OEM
for selecting the correct kit.
· The Ridewell HCV is interchangeable with most other brands of valves.
