Same aisin as in the ram. As69rc, overkill really.

So this thing has a engine and transmission both designed for medium duty commercial truck usage and a 13 inch rear axle. We know that Nissan has suspension and running gear in their parts bin capable of supporting a 10Kish GVWR truck in their NV3500 van. Maybe this thing is really a 2500 series-spec truck, but they are not marketing it as such because it has considerably less hp and torque than the big 3 diesels.

The 13" ring gear is likely a mis-print. A dually Ram 3500 only runs 11.75".

13" is well into 450/4500 territory.
