Those bags look like the standard C10 fronts (2600's/SS7's/Firestone 224c F6873) have about a 6" recommended ride height @ pressure. If/when you deviate from that recommended pressure, it impacts ride quality.

I ran that same size bag in the rear w/no bracket & it took only ~25psi to achieve my desired ride height (top of axle tube @ bottom of frame rail lip/approx. 2.5" from bottoming out on the c-notch). Now, I also had lowering blocks in the rear which should be a wash for your bag bracket since they prob both were similar in height. Below 30psi the ride was too bouncy & felt like it was basically too much for the shock.

You might want to set it up & verify dimensions. The smaller Dbl. Convoluted bag (2500/SS6's/255c F6781) are ~5" @ recommended ride height @ pressure (40-50psi likely). You get a much better ride quality w/the correct air pressure.

Food for thought. You sound like you weren't planning to go as low as mine was so you might be ok. I figure it's worth mentioning while you're still in the build stages.

A pic for reference . This was a bolt-in C-notched frame, bags directly bolted to the frame/Truck-Arm, & 1.5" blocks. I know it's a different year/body style but the chassis' are almost identical for the ride height concerns/comparisons....

Scoti,
I so appreciate your comments and thoughts! That is such a great help to me. It allows me to understand what i can do if what i het is not enough. Thank you for your time here!

No problem. I would just make sure you can mount the smaller bag in the same set-up that way if it does seem it's necessary, you're already set-up for the task.

What brand/manufacturer are the bags?

I am using EZ Air Ride full Deluxe kit for my C10

I know where you sourced it from. I don't know what brand parts they supply. I went back through & found an image that revealed the bag manufacturer (Air Lift)....

i just checked, they are 2600 series.
Thank you for doing this. I understand alot more now and i really get what you were talking about in the ride height vs other.
Surprise, this is my first air bag install. I really like the idea, been in air bag truck and loved it, and so here I go. lol.
Damn, i need to come visit you and buy you and your significant other one hell of a dinner and drinks! I really appreciate your time!!
Anyone reading this that is somewhat new to this site, this is what you can expect from not just Scoti, but there are others who will help you with things you never even knew about.
God Bless you my friend.
Im more excited now than ever to get back out there and work on it now. lol

Again.... No problem.

To be honest, it gets even more confusing because all bags are not created equal. Some bags are inherently 'stiffer' vs. others. Some have bump stops where others don't. Some require fitting adapters vs. threading the fitting directly in place (less chances for air leaks).

I went back & looked @ your set-up again. I missed that you do have lowering blocks as it's assembled now. You definitely will need to scrutinize the set-up if it doesn't ride to your satisfaction @ the height you desire. I recall mine only needed ~25psi for my desired ride height. At that pressure, it did not ride smooth & was overworking the shocks. Once it was around 40psi, the ride was much better/smoother but then the rear was prob ~2" higher than what I wanted (to match the static front drop).
