Springs are pretty straight forward. As long as you seated it correctly, there’s not much that can go wrong. When I swapped springs on my 98 to drop springs it took a day or two to settle and get the squeaks out. On my 94 when I pulled the factory springs and cut them, there was no settling... it was just low.
Make sure you are measuring from the center of the wheel to the lip of the fender and not from the ground. Also, how long were the first set of springs in the truck?
