How about a front spindle lift?
I've got one of these on my 99 ECSB NBS 2wd. With the taller rear blocks, the truck is pretty much "leveled." I'm actually not a big fan of leveled trucks because adding a bit of weight to the bed causes a negative rake. I prefer factory rake. I honestly can't remember the kit that I installed (3"? 4" maybe?,) but I don't remember if I actually measured the before and after. I wish they did like a 1" less kit to maintain rake. I've had that kit on that truck for a while now. I plan to lift the rear just a bit more at some point.

Also note that the front tires get pushed out a bit. Not much. I run LT265/75/16s.
