K30 rear spring question.

[rs74]

If I take the overload springs out will I have to worry about the rear of the truck dropping any. With these springs in there it rides way to rough. It's like it has a solid suspension. I took a 9" torpedo level and put it on the bed rail and it has about 3/16-1/4" of rake from rear to front. So it could use a little drop in the rear to level it out a bit. I am going to have to measure to see what length of new U-bolts I will need to replace the old ones.

Not good pics but here they are.
