Thanks

NBS=New Body Style; body style for the full-size GM trucks/SUVs changed in '00.

And in case you come across this...OBS=Old Body Style ('99 and earlier, although I don't remember if there was a previous generation Tahoe/Suburban/Yukon prior to the one preceding the current NBS one).

We need more drivetrains. rzkz8k - thanks for sharing that info. 'NBS' stands for New Body Style, i.e. 2000-up on Tahoe & Yukon, 2001-up on Denali & Escalade.

Take care,
Jerry

Otherwise, I'd be willing to bet that if the Yukon full-time 4WD option was available for the Denali, there would be more than a few takers for it.

The difference is in the transfer case and what GM calls each system. Denalis have AWD and Autotrac in the other vehicles. No 4WD low in the Denali, I wonder why they (GM) decided that.
