Like needatruck said, the Titan rear axle but it's pretty much identical. Then you're up to 3/4t Ford stuff because you have to have the ABS tone rings for the speedo and transmission controls. And you have to run 38/40s to get the clearance. That's just too much for a DD.Any 1/2 ton parts swap in? I know some of the Titan front parts can be swapped in. How about the rear?
