02 silverado lift kit

[salrod00]

i got a 2002 silverado 2wd pickup. i want to raise it with 4 inches with suspension and maybe 2 inches on body. But for now i just want to do suspension. i know that i can put a 4 inch blocks in the back and it be enough. But what i cant figure out is how to raise the front. i dont think that it has torsion bars up front but i might be mistaken. Does anyone know how i can raise the front without it hurting my pocket. any advice or pics would be great..
