If you've ever done this before please add your input.
This is a leaf pack from the front of my Jeepster. They are Alcan Springs built in about 2005. They are too tall and unload severely when I get the rig close to verticle. My shackles as they are now are completely vertical. I'm hoping to flatten them to lower the front end a couple inches.
I laid the assembled pack on the floor and drew a line around it and then dissassembled it and did the same for each individual leaf except for the one with the clamps on it.
I'm thinking that I'm going to de-arch the front of the springs about 3 inches. I'll do this to the main and military wrap leafs and maybe the third one. I'll leave the rest alone.
What do you think my results will be? OR how much should I bend them?

I've done the opposite to a pair of YJ springs. They had S-shaped on me and lost some lift. I took the spring packs apart, and flipped the main leaf over with the eyes on the garage floor. I then measured from the floor to the top of the spring to get my starting point measurement. I stuck them in my Harbor Freight press, starting at one end, and moving it in probably 4"-6" increments bending the spring just a little at each location and repeating and checking until I had gained the amount of arch back in the spring that I desired. I then moved on to each of the other leaves bending them to match the contour of the main leaf I had started with.
