Rear Bag Isolation - question/opinions?

[JayG]

I'm currently adding a larger fuel tank from Fuelcellguy and am replumbing my rear sleeve bags. I've heard comments about separating or isolating the rear bags from each other, because when you go into a corner, the shifting or lean moves air from one bag to the other and that they should be isolated. I run a large rear sway bar and it's not really an issue at this time. However, I'm getting ready to help some local guys with their projects and not everybody likes a rear sway bar.Most of the diagrams on the large air ride supply company's web sights show a common feed line to rear bags. Is the air push from one bag to the other an issue on rear bags? (I'm more into handling than dragging) Thanks in advance for your opinions and input.

It's much more of an issue up front, but if you have a concern, run 4 valves out back. 2 fills, 2 dumps. This will isolate them.

Its only two more valves and a couple fittings. Theres probably a grand invested already

The question really was if anyone had encountered this theory or actual happenstance. I know how to solve the problem, if it is a problem(really not trying to be a smartass here), I was only curious if it was a real issue or only a theory that had been mentioned to me. I just figured with all the experience here, somebody may actually have had an experience with this. Thanks. And I do appreciate the input.

Well, I don't have any personal experience, but I have quite a few friends running only 2 valves in the back and I've never noticed anything while riding in their trucks. If you're running a rear sway bar it'll be even less of an issue. The reason for running 4 valves up front is because the front end is so much heavier, and in cornering the front has much more body roll because of this.

It is a problem. We are re-doing a system on a Riviera that somebody installed in the same manner. At about 75-80mph the rear of this thing floats like you wouldn't believe while cornering (mild corner like on a freeway). I always recommend isolation the first time... or you will most likely re-do it later!

yeah, what he said..lol

[JayG]

Thanks guys. I felt that on a long sweeper type corner with no rear sway bar that it could get wierd feeling handling. I'll make a point to isolate 'em all, can't hurt.

whats the big deal about running rear sway bars?

[laidout86]

i had only 2 valves on my first truck 98 s10 and it was a big problem...i would recomend on runnin 4 valves out back if u are worried about it 4 up front is a MUST!

[jimmydean]

A lot of setups I see show only 4 valves, your saying run 8 instead? There is a great basic setup I'd like to get, but it includes 4 valves. I just need 4 more valves and with connectors?

[PBFAB.COM]

The "eight" valves referred to are the parker style electric valves. One lets the air into the bag and one lets the air out of the bag... 2 for each bag. Not all air systems use this style of valve, so before you order 4 more, make sure you need them!

[67Fleet]

Right, one fill, one dump for each bag. The valves are the gatekeepers for your air system, and are controlled by your switchbox. You can run 2 valves out back with a tee in the middle, but as already stated it is a good idea to spend the extra money and go with 4.
