Sure, but I don't have the Yakima system for the Denali yet. I've only spec'd it out because I'm running into the limits of the factory cross bars on mine (I need to be able to put 4 bikes on top but the factory bars will only support 2 before they start to bow and feel unstable). I do have the Yakima towers and bars though that I used on my '02 Suburban and they look like they would work with the landing pads I linked for the Denali, so I will probably buy those shortly. Hopefully the same would be true for the pads for the SLT roof rails.
But, at least you can see how the roof rails on the Denali might differ from your setup. Seems like the key will be to find the right landing pads for your rig and from there your old towers and bars should hopefully bolt up just fine.
