Did a 4.10 swap. These 3.55 are the Dana 3.55's. There OEM and we all know there better than AF. I also have a carrier for one. good quality set no blems. Make me an offer.

 

Some people are confused. Yes they are both Dana 60 matching set not a 60/70 combo they are both Dana 60 gear sets. Sorry just got a bunch of PM where people are trying to tell me it had to be a dana 60 front and 70 rear. I think i would have ran into that problem when i did the swap and tried to put a dana 60 4.10 in a dana 70.

 

well these trucks did not come with a dana 60 rear is why everyone is sending you messages. Who did you get the 4.10's from? There probably is a way to fit 60 gears in a 70

 

Its because the truck I took them out of was a 99 3/4 7800 gvwr GAS. These will go in any Dana 60 besides Fords reverese rotation. I also installed lockers front and rear.
