    Okay I've got a question. I've clued in from reading posts that OBS is the older 88-98 chev and NBS is the newer one, but I'm still lost as to what the BS stands for. Not to sound stupid but if anybody could explain that I'll learn something new today.

    Oh its really that simple. I figured somebody would come back with the bull **** comment lol but thanks crete. Now that I have that figured out Im gonna say OBS is better. I like the interior in my yukon way better than my dads 01 sierra, way more room. I will admit his 5.3L hauls way more ass though, but it might be because of his 3.73s as opposed to my not so optimal 3.42s.

    Now that you have it figured out time to learn again. NBS is 07-09 and OBS is 99-07 and pre 99 is a dinasaur. 07 has both, new and old. :dizzy:

    Now that there's a few OBS's...guys (including those at the dealer) refer to them as:

    '07-up = NBS
    '99-'07 = Classic body
    '88-'98 = OBS

    Designations can be confusing since different people refer to them in different ways. Which is why many also go by the original platform designation..GMT400, GMT800 etc...

    Don't forget the mid years at 07 and 99.
