You need to post some pictures of what you have going on.
Are you doing ruf? It sounds like you just added a bunch of leafs to a stock front pack? Maybe consider picking up some emu springs and going from there.
To answer your question, there is a little over an inch of clearance, on all my trucks. They get real close at full drop and 7 leafs in a ruf pack is the max before spring/tie rod clearance becomes an issue. That has been my experience
