This is a used factory 4.88 IFS ADD diff. I bought it 3 years ago and put the ADD needle bearings in it as well as a Spartan locker and new oil seals. It performs extremely well but I highly recommend having manual hubs as it is hard to turn and only engaging one hub helps tremendously for turning, I do have WARN HD hubs that I can sell for $100 as well. I am doing a solid axle swap so I don't have any need for it anymore. I can sell it as just the diff or the entire ADD front depending on if you want those parts or not. $450


This WILL work in a non-ADD front, you just have to move the oil seal onto the diff on the ADD side and put your non-ADD axle tubes onto the diff.

 

I also have an open 4.88 front 7.5" diff for $300

Locked diff sold still have the open diff

 

Shot in the dark. still have the 4:88 front diff?

 

No I sold it right after that. 4.88s sell super fast
