Absolutely, now I can say after 9k miles which includes this 2500-mile rugged Baja trip. The NP241 is the DLD - it did well on this over 12k lbs
loaded rig. It got me out of the mud at Shell Island and also from deep sand on the way to Morro Sto Domingo. Although the DHD is a heavier duty
model, I've read numerous failures due to cracking.
The DLD came on the lighter duty CTD's, only the 2500's with the automatic and Dana 70's. The 3500's, high output engines, and some 5 speeds with
the Dana 80 came with the DHD. For those heavier duty trucks, there is a reason for the heavier case. It seems to me that you have a very heavy truck
with a built CTD engine. Long term, more than 9,000 miles, is not a true test. Often cracking comes from those who lift their trucks and screw up the
driveshaft angle, making it very hard on the slip yoke. No way am I dissing you, I hope you are right in the long run.
The reason I ask about the 47RH is because they are notoriously weak. Stock, they can barely handle the power of the CTD. Once you start modifying
the engine and or continuously hauling a lot of weight, they will fail, guaranteed. The only reason I ask these questions is because you have made a
very interesting vehicle. Using the CTD is a good choice, but some of the other components that Dodge used are not really up to snuff. You have built
your engine and are hauling a lot of weight, some of the Dodge components are not up for that. |
