    yea i figured they had totalled it. crawl under the truck and look for a tag on either the rear diff cover or on the rear diff itself it might be stamped onto the axle itself. but if u find that and look up the number it should tell u what ur axle ratio is.

    Get the VIN# and take it to your local chevy dealer parts dept and they can tell you everything you need to know! since its a z71 like mine its probably a posi rear, can't remember what my gear ratio is off the top of my head, sorry


    :great:

    my new truck is a red 06 z71 with 40k miles. its the LT package. we were REALLY lucky to find it. it's the fanciest thing i think i've ever seen
