Air bag ride height help

[jmlcolorado]

Hey guys!
I'm getting to the point in my build that i need my bags rigged up.
My setup is completely out of the norm for most of the builders on this site as i don't have drop spindles, rather a 6" Z in the frame under the cab.

I would like to use the factory spring mount location in the rear to mount the bags, with some bracing/plates of course. And ill use the typical plate at the front spring perch up front.

I have seen a few folks that use the factory location in the rear for their bags and their getting around 11" of lift. I really only want 6"
Same for the front. I only want about 6" of lift.
I am planning on using a bag cup of some sort up front.
As it sits now, the lower control arms come within 1" of contacting the upper spring mount in the front, and in the rear, i lay frame with a 2" pipe notch.

SO, do you guys have a idea of how much you get in the front using a RE7 bag or something similar?
I'm really looking for advice as to how to accomplish getting only 6 inches of lift all around.

Bags are new to me so a few more questions.
At what point do manufactures suggest the ride height be at? I assume if a bags max hight inflated is 11" and fully compressed is, say, 4", they don't want you riding at 10" all the time. Is it in the middle of max and min height of the bag? for example, 7.5" ride height?
How is that limited so not to overextend the bags? Do the shocks take care of that? If so, how do you find the right shock? Measure shock mounts at ride height then again at compressed height then find a shock that fits those measurements? As i type that out, it seems you wouldn't want the shock to be at max height either so you'd need it above ride height. This leads me to believe that strictly air pressure sets this. If so, what is a normal pressure in front and rear? When you fill your bags, you just have to be sure you stop at that particular pressure right?
So many points to cover, sorry guys.



I know ill get a few punches for having scrub line issues with having the z in the frame and i completely understand where your coming from. I assure you i am taking my time on this project and doing as much research as i can before i execute anything.

Obviously, this z would pose alot of problems using the C10 body, which I'm not so heres the project. Thanks in advance for your input.
