Im trying to lift my ext cab short bed 2000 chevy silverado 9" front 6" rear. I am going to get 3-3 out of that with a body lift so basically 6" front 3" rear suspension.

I have a 3-3 suspension kit now. 3" lift springs 3" blocks. I got it today its in the box I dont want to put it on till I know how and what I am doing.

If I put these springs on the front I was told stock shocks will work for a little bit on 3" but its better to get new ones asap is that true? If so is it possible to use stock shocks for temp on 6" lift too?

Also how can I get the other 3" of lift suspension wise in the front? I was thinking spring spacers, but will that work. If I got 6" lift shocks could I do 3" springs and 3" spring spacers, and that be all I need to do, or is there other things that come in play like camber or any relocating or anything?

Also if any1 has a body lift kit or spacers let me know.
