Need 4" lift advice for 04

I have an 04 Z71 on 33's with the tbars cranked. Bad bump steer, upper control arms are about bottomed out, no way to live. The problem is the look and height are perfect. I have no want to go to 35's.

I have seen the BDS 4.5", Rancho 4" (and discussion that its more), what else is out there that would allow me to run stock CV angles and clear 33's? I don't want a body lift and I want something that won't push the front wheels out.

Any help, especially pics of others rides would be most appreciated.

I found some dropped upper control arms on ebay, mine were maxed out and lasted a year. Also found a 2" front axle drop on there.

Do you have the link to the axle drop?
