Update: Got off the phone with All-Pro, I was asking about their 4" lift system.  If I ran my stock front hangers and stock lift shackles up front I should end of with about 4" of lift up front.  This is about my limit as far as height goes.  Does any one know if the Marlin 4" springs  are typically taller than All-Pro's?  Any one have a similar height measurement as above but with the All-Pro kit?
