Yeah, the Np241D is pretty much just a beefed up NP231D. It has the 6 planetaries as well as larger bearings all around and slightly thicker shaft. But really, where the splines are is all the same for both the front and rears.....so if the shaft was gonna break under certain circumstances for an Np231, it would do the same on the Np241. The reason the Np241D is pretty much a beefed up Np231D is because the Np231D is not like the original Np231! Np231s are found in Jeeps and other small 4x4s. The Np231 in the Rams is an enlarged and built up Np231 just so it can survive in the Ram. So really, the Np231D could be considered an Np241 when compared to the orginal 231s anyway. Ditto what Beast and V10sport have said about the torque and the PTOs. I would love a PTO option, but I couldn't sacrifice what I was wanting to do in order to get PTO.
