Air bag operation - The 1947 - Present Chevrolet & GMC Truck Message Board Network

4oldcars · 06-03-2013, 09:39 AM

I've got this Blazer (2wd) that already had air bag suspension installed. I'm old and air bags just ain't me. I took out the front ones. Went back to springs. I'm gonna keep the back ones so I can tow. I currently have the original set up - - 2 air compressors, air tank, etc. I'm wondering if I could/should remove all the above (poor installation and take up a lot of space) and just use a schrader valve to air up the rear bags. Anyone been there, done that?

Easily, just run the two lines from the rear bags to somewhere around your license plate, install the schrader fittings and you're good to go. No need for compressors, tanks, relays, or anything.

You could possibly "recycle" the 2 pumps and tank.

You could do that if it was me i would find a small tank and compressor which is easier to hide.

I have the rear bags only also, for towing. I have two schrader valves at the rear license plate.

I'm assuming by your comments that 2 valves are better than one. I had in mind to tee the lines to one valve. Not a good idea? Thanx for tha comments.

T'd airlines allow shift of air pressure from side to side when there's leaning (in a corner) thus making the issue even worse. 2 valves (or separate airlines w/schraders) isolate each bag independently.

Thanx SCOTI. As usual, I wasn't thinkin ahead. Sounds like a plan.
