Rear Air Bag setup done simple??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

72 Cheyenne402 · 06-22-2007, 11:17 AM

Right now I have a 2.5 drop in the front and a 4" spring in the rear. When I put a load on the rear springs they just bottom out. I am thinking about going with airbags on the rear of my truck just to adjust the ride height under load conditions. What would it take do do this as a simple setup that could be expanded later, maybe?

Thanks

"Swapping to manual fill bags will get you where you want so why not bags? You're going to go through the effort of swapping springs anyway.... installing a couple of bags isn't much more work.

From SuicideDoors site:
255c 2500# Firestone air bags @ $70ea x 2 = 140
25ft 1/4" Reinforced DOT air line @ $6
90° elbow fittings @ $5ea x 2 = 10
Schrader fittings @ $5ea x 2 = 10

Grand total for everything = $166
Price for 5" drop springs from board vendor GMC Pauls = $115

$51 difference to get that 7" drop & still tow a load....."

Scoti,

Is this something you have done? Do you have a pic of this setup?

Yes.... That's how I initially installed the bags on my 68.

I ran them that way for almost 3yrs before installing a tank/compressor w/controls. I've added more again. The front has bags now & I switched to Slams (I thought I would try them out). I also re-engineered a couple of things on the suspension to work a little better.

As far as pics.... there's really not much to it. Bags in place of rear coils & 2 airlines running down the framerails to the bumper where I mounted the 2 schrader valves (they were installed behind my flip-up license plate).
