my front leaf springs on my k30 are sagging pretty bad. it only sits about 2 inches from the bump stops and you can see where the bumpstop is hitting the u bolt plate. but when i hit potholes it is freaking slamming hard does anyone else have this same problem...

My K20 used to have that problem, but only with several hundred pound of snowplow hanging off the nose. I added a couple of leaves to the factory spring packs, hopefully that "fixes" mine.

AFAIK, there isn't much space between the spring and the bumpstop. (mine sat about 1 1/2-2") Sounds to me like your springs are tired. This is assuming that your running factory springs.
