This is it. Let's leave the debate of running 37's on stock axles out of this particular discussion. The rest of the process is still very interesting. Functionally, this is better than the AEV kit. Who knows why?
Lots and lots of threads out there on DIY high lines. Pretty simple, IMHO. Pull the fender, bolt it back into the tub one bolt hole higher. The grill area gets a bit funky, but nothing a body hammer won't fix.
I think the two hardest things to figure out would be where to put the stuff mounted to the fenders, and how to finish the hood edge.
