Air Ride Setup Idea.

[layingC10nK5]

U can have a 6 valve, even a 4 valve set up with no air transfer. All u need to do is run a check valve before the bags and that will prevent the air from returning. Take a look at this pic...( not mine) found it on a previous thread.

The best place for the check valve would be closest to the bag, that will keep the bag aired up in case of hose failure.

N2TRUX you are correct ,theres a million variables. Im sure a burban with worn out suspension could get some good body roll in the back.
I personally think 8 valves is the only way, but i started with 4 on my first truck and had minimal roll in the rear . thats just my experience. Assuming its a chevy truck with a properly setup rear 4link.

i guess if you wanted to you can do about anything with a bucket full of tees, fittings, and check valves.
what are we talking about $100 difference between a 6 valve setup and an 8 valve setup?? im guessing $40 per valve, 20 ft extra hose at $1 a foot retail, and a couple of fittings.
I know every penny counts i'm on a tight custom budget too.

I totally agree and have put my mind stuck at a 8 valve setup and just going to hold off would be the right way to go about it and have it done correctly all at once.
