Both sets have been in my 2002 silverado, 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 on either set.

 

Bump, I need to sell this stuff

 

Do you have front and rear for 3.73?

 

Just the rear

 

10 bolt or 14 bolt?

 

8.6" 10 bolt
