I just bought the truck and am interested in using the following set up (a fellow f150 member has this set up too). Looking to install an autospring 2.5" level kit on a set of Bilstien 5100 shocks set at "0" up front with a matching set of Bilstien 5100 rear shocks and a 3" block. For the time being I'd like to install a set of Nitto Trail Grapplers on the factory chrome 18" wheels (LT295/70R18). The goal would be to someday upgrade the wheels to a set of Platinum 20's running the same Nitto trail Grapplers but with the 35"x12.50x20. With either set up is the projected leveling kit enough to prevent any modifications to the inner fenders and such or should I scratch the level and go with an minimal 4"? I am working on a budget and I'm done with my younger years of wanting a jacked up truck. I'm open to anyone insight and if I get flamed it's my own fault for not comprehending the info that may be out there. I appreciate your time and efforts and look forward to your responses.
