I'v read up on this truck a bit...
Fairly beefy axles..not sure exactly what, but they are probably AAM. Probably d44 equivalents. Lockers. Manual tranny (heard about a 6 speed but itll probably be a nv3500 and some slushbox). 4.10 or 4.55 gears, depending on the tire choice which is 33/35's which I think a 17 inch wheel is standard with either. Hemi 5.7 is the standard (and only I believe) powerplant.
When, and if, it comes out, it won't be as glorious as the prototype. We will still see the truck, but probably in the form its flaunted as currently, it will cost a pretty penny. I'm willing to bet they will come with the 4.7 and the old 360 as an upgrade, with the hemi being an option. I don't know about a locker in the front, but it will have to be selectable...And quite possibly another option.
Either way, it looks like its gonna be a good truck and its just another step in the ongoing truck war.
Expect GM and Ford to have some similar vehicles in the future. Until GM offers the exact truck I want, my 3/4 ton is, and probably always will be the ultimate truck/moneypit in my eyes
