The offset of the carrier.  The D61 and D71 have the ring gear offset so it can run a taller gear that would not be possible with the typical D60 and D70 design.  You are pretty much stuck with the odd carrier with those axles though a few people have found ways to mount lower gears in them.

When the Cummins was first introduced, they were offered with two transmission options, the 5 speed Getreg and the old 727 Torque-flite. The Cummins has a low rpm range, red line being around 2200 rpm. To get to highway speeds, most diesels really benefit with an over drive in the transmission. The Getreg has an overdrive gear, but the 727 didn't. Dodge decided to take the next best option and use very tall 3.08 ratio gears in the axles to give an overdrive effect. This required a unique offset differential carrier. Dana would produce the unique axle for the Cummins/727 trucks. Other than the carrier, the axles are similar in design, and they can accept other ratios with modifications.
