Heath, I really do think your going overboard a tad. If I were you, I would get that DT-466 mounted up and then see if you can break that axle that you already have under your truck. There are guys on the dyno's turning 1000+ HP with 3/4 ton axles in their Dodges and PSD's. To break it, your going to have to keep the tires from spinning. They are going to break loose long before they break in two. I can appreciate wanting to beef up the truck for the sake of scaling, but by the time your said and done, you may have well mounted your pickup body on a S-1600 chassis. What your doing, others will want to do. And like I did with the Bronco, you have to prove that your lighter running gear is or is not up to the task. A lot of people told me that 1/2 ton axles would not carry a diesel, and that the torque would kill the Ford 8.8. Neither turned out to be true, and I could have kept those axles as long as I wanted to. Keep in mind that truck designers expect people to abuse the snot out of something when they buy it. They overbuild it so the company keeps a good reputation. Not only will you build your truck, but you will take care of it, and when it comes time to do something that you would only do if it was someone elses truck, your not going to do it. Unless your going to enter the NTPA pulling circuit, and take the license plate off the back of your truck, I think you may have your priorities out of order.
