Why Do Trailer Hanger/Equalizer Kits all Use Different Height Suspension Hangers

Question:

I am building a trailer from scratch and have a question about different size hangers and what it affects so I can determine the best size for my trailer. What is the difference or purpose of front/rear/center being the same size versus the front/rear being shorter than the center. What do differences is length cause?

When the suspension hangers, equalizers, and shackles are installed from a kit like the part # APT3 the goal is to have the leaf spring as level as possible. The different height hangers is offset by the height of the equalizer and shackles so that when it's all said and down everything is at a level height. Check out the picture I attached of a kit like this installed to get an idea. The great thing about these kits is that the correct height of everything is already all worked out.
