    Default what differential is on trailblazer?

    im considering buying a used trailblazer, probly an 03 or 04. does this car have the stupid g80 locking differential that the tahoes/silverado hds do? if not, what kind of rear diff does it have?

    also, if possible, could i see some numbers of what you guys with 03s 04s or similar models/engine are running in the quarter mile or 0-60?
    thanks!

    If it has a locking diff it will be a G80 but it might not have one. You need to check the RPO sticker.

    I checked the auto wrecker interchange .... if it is equipped with posi-traction, it will be the G80 ...

    Why would you not want the G80?
