I had the spring pack that Slotard is installing. I removed the following springs. I installed 4 inch lowering shackles and hangers at the same time. It netted me about 6'' of drop with the combo. The ride was MUCH better thought I didn't drive it a lot before I tore it back apart.
Stock pack.

Removed springs.

I replaced the center pin at the same time.

Just removing the leafs will likely get you level depending on the condition of your springs front and rear.
