Engine/Transmission (1998.5 - 2002) What rear end?

[Wyatt 1]

Any help with this would be much appreciated, I have an 02 2500 4x4 with a 5spd manual transmission, what rear end should it have? I have looked and looked and come up with either a dana 80 or dana 70 which one is it, or neither? I recently bought the truck and I have been away on buisness for 5 months so I cannot go out and look at the differental or take any measurements. I am adding some power and I am trying to cover all the bases, if needed, thanks for the help, Henry.

I would say the dana 80 which is on my 01, but they may have changed that for 02? anyone else know?

From 1994 to 2002 all 2500's with manuals were D-80 Hibrid's, meaning the center section is D-80 and the brakes, spindles, and wheel bearings are D-70, all auto's were D-70's, 3500's are full D-80's auto's and manuals.

Absolutely correct, you have a D80 hybrid.

Your rear end is not one of the bases that needs to be covered. It has covered itself.

The Dana 70 and 80 are virtually unbreakable.

Thanks for the reply, what about the front axle? Any parts or pieces besides u- joints that are prone to breakage under pressure of motor upgrades? Same for the transfer case any known problems?

Your truck has a Dana 60 Front end. These "little" dana are what was used on the half ton trucks for rear ends. These are also stout little axles if you are going to keep your power levels reasonable. What is reasonable? The only time "I" have ever seen one break is a 800+ HP truck that was pulling a 40K sled down the track when it broke a shaft. If you want to sled pull you will need to upgrade the front drive shaft or you will either break the U-joint or twist the shaft like a pretzel. Now that was a funny thing!! Well for me at least, the owner of the truck did not agree it was funny :{



Transfer Case depends on which one you have. If you have a snow plow prep package or cab lights you most likely have a 241 DHD which is the heavy one. Those are almost unbreakable... . even you high HP Pulling Trucks. The other option is the 241 DLD which is the light duty brother the the DHD. Also a very good transfer case. Can be broke under Truck Pulling conditions and stupid pavement acts.

You can look on the red tag on the back of the transfer case to find out.

Very good info Whitney, nothing but the best support from this site, dont plan on pullin, yet, we will see?? But for now I guess no need to upgrade any of the drive components seeing as they are stout enough already, thanks again for the help everyone,
