3.42 Diff?
Since my differential was leaking and out of warranty I was looking into upgrading to a 3.42 diff. The part number I have for the complete assembly is 12551769 can anyone verify for me? Also any suggestions for the best price to get these? :seeya

It's only sold as complete set.
Who are you buying from? Most vendors here don't list it by it's
internal GM parts number though.
Brand new you're looking at about $900 give or take.
Used...? $500, but buyer beware. :cheers:

I do not know if that GM part number is the MN6 3.42 or the hardened Z06 3.42 . But it's one or the other.
