Both sets have been in my 2002 silverado (8.6" 10 bolt), went to 4.30s. Don't need these anymore and don't want to store them any longer. 3.42s were the factory gears and have around 100k on them, I was told the 3.73s were factory gears as well but I haven't verified that, they have around 100k on them as well. Both sets look very good, I can send pictures via text message. $100 shipped or $75 picked up on either set.

 

Bump, I need these gone

 

Are these series two carrier? I'm thinking not bc of them being in a truck but figured I'd ask

 

I honestly don't know. They came out of a factory 2002 silverado 8.6" 10 bolt

 

Bump.

 

Interested in the 3.73 gears. PM sent
