I would agree on the weakness of Dodge drive trains. I’ve been to a few deisel truck pulls in recent years. Fords and Chevys did ok. Seems like every other Dodge truck that pulled broke the drive shaft back at the differential.
Of course, at a truck pull, it might have been because those modded Cummins engines have monster torque. The Duramax's are momentum pullers; lot of ground speed. You can get more RPM's out of the V-8 diesels. The old Cummins pulls with shear HP and torque. I've pulled both. Prefer the Cummins, but you need a Duramax to win nowadays. You see very few Ford/Powerstroke pullers. Cost to much to modify.
