    hey guys i was wonderin if u could help me here because ive gotten mixed answers. i have a 10 bolt rear end in my Z71 and it has never not given me the traction i need when off road but i was wondering wut kind of differential i have in it? of course the entire rear axle is just a stock 10 bolt but i herd somewhere that w/ the Z71 option that you get a locking differential standard. any truth to this? i was just wanting to know and i thought this would be less hassling than pulling the cover off lol:biggrin:

    thanks!

    Look in the glove box for the option sheet.

    It should have a lot of numbers.

    They are all the options installed in your truck at the factory.

    I have the 188 page list, ya it’s that long. But I believe Patrick has a link to the list.

    That will tell you what you had in the truck when it was built.

    I forget what the numbers are for the rear axels.

    001 to 009 are axel ratios
