What rear end does the 2000 4wd trailblazer trim have?

 

Do you have an rpo code list in your glove box? There was a lot of generic versions, but also some specialized for the purchaser...

 

 

You have a 3.42 rear end


if your looking for one, find one with the gu6 and the g80 code, itll have the "gm posi lock" as well as the right ratio
