I need help and KNOWONE seems to know about it.

Is it possible to drop a 2001 chevy silverado 1500 4wd z71?   Yes i know, why would i drop a 4/4, but its paid off and i want to keep it.  Anyone know my options?  I think i can do the rear notched with a flipper and blocks... but what about the front...  

You could also put shackles and hangers on the back. It would drop it 4 inches, Im not real sure about the front with it being 4wd, you could throw on some coil springs on it, and adjust the torsion key.
