Looking to put a body lift on my 2004 f150 fx4. Does anyone have any before and after pictures of their rigs? Will it lift the truck up a full 3"?

 

Yes, you'll get a full 3" all around.

 

Looks good when gap guards are properly done, along with coating the frame with POR-15 or even spray painting matte black if there is some surface rust. It is an involved job, almost worth spending the money for a true lift. If you can install it yourself it is worth while.
