I chose to go with a late model rear that has factory disc brakes w/ e-bake. It came out of a GMC truck with a 6.0L / 4L80e and has 4.10 gears and factory locker. This is an AAM 14 bolt full float axle 8 lug with a 10.5" ring gear.

I had purchased a complete low mileage rear from a diesel truck with the allison trans and it was geared 3.73... This is even bigger with 11.5" ring gear as opposed to the one above that had a 10.5" ring gear.

I decided to go overkill with a D60 front and will probably never use it to its full potential, but I will never have to worry about it when I'm done.. plus the cool factor...

Again these are 8 lugs and would require new wheels... as well as some fabrication to get the rear axle under the truck. I picked up a set of Hummer H2 17" wheels for cheap so that was a plus.
