4 valve system

[au03z71]

Anybody ever seen a 4 valve system utilized? Basically just a common fill and dump for the front and a common fill and dump for the rear? I'm not really interested in being a switch maniac. I just want a good ride and a mean stance with the ability to alter ride height.

Thanks

The vast majority of people I know who went this route later went to 8 valves (or 6). The 4-valve setup has an inherent problem in that it allows air to be transferred from side to side. As a result, you end up with a lean problem when cornering because the air on the 'heavy' side transfers to the other side, thus causing more lean... rinse and repeat. The 8-valve setup isolates the sides from one another, which eliminates this problem.

Wouldn't check valves cure this problem?

yes, but they are pretty close to the same price as a solenoid valve ... sooooo

and without the control.

check valves at ace hardware are around 10 bones a piece..........

I wouldn't advise putting the kinds of pressures seen in a bag when it is being compressed by a 3,500 lb truck on a $10 check valve ... but that's just me.

[joe231]

if they are rated for 200-250 psi working pressure, burst strength is typically at least 3 times that. The factor of safety, i believe is somewhere between 3 and 5....but I can't find the page right now to get the specs....
but i agree, it is not much in the way of savings, and the loss of function is probably not worth it......

3X safety factor on all 316 Stainless Steel fittings by Parker Hannifin ... can't say for import variety from Ace Hardware ...

6 valves or nothing, the weight transfer is def too much to put on a check valve...were talking about your life here!

I ran 4 valves on my 88 for years and drove it daily. It It had hardly any air transfer in corners.But I still have my front sway bar and stiff slam ES-72s.

You could try it and if you dont like the way it drives. Just add more.Youre not going to crash cause youre truck leans in corners.

So if I pull out 4 of my 8 valves, I'll no longer be able to crash?

With 4 valves, the lean will likely be significantly more than even a stock vehicle with stock suspension. Rubbing/cutting tires is not a good thing. Increasing the body roll characteristics beyond what the factory thought was safe is not a good thing.

[redsled04]

I didnt mean you wont crash. But the lean wont be significant enough to be the cause if you know how to drive.Most of these old trucks get driven with old wore out stock suspension and lean way more than a rebuilt and bagged with four valve suspension ever will.

I just know from my truck. Mine drove great but not everyones will.

OK,... say you do install check valves in-line to the bags. You hit the fill button. Air goes to the bags. Air will not transfer because of the check valve. Now,... how do you let the air out? The check valve keeps the air from transfering back out of the bag.
4 fills.
4 dumps.
Why not make your truck enjoyable to drive.
I'd leave it static before I'd run 4 valves.

I never said I had check valves.Just 2 valves for the rear and two valves for the front.

I enjoyed it for about 50,000 miles this way.Most the time about an inch off the ground.

Redsled04,... I wasn't neccessarily talking to you. Sorry.
Just everyone that says to just install check valves. These check valves just flow "one way".

Its all good.The check valves definatly wont work the way you described.
