If your 2003 GMC Yukon Denali came with a factory roof rack that included crossbars that run side to side, then a 21 cubic foot box like the Yakima SkyBox 21, # Y07184, is a direct fit. The 21 cubic foot boxes are the largest we carry.
If your Yukon has side rails that run front to back but no crossbars, you would first need to add crossbars to mount a cargo box. You can use Yakima RailGrab Towers, # Y00138, and Crossbars, # Y00409. You could then mount the SkyBox 21.
If the vehicle does not have any type of roof rack, but has tracks that run front to back, you would need to add a few parts before mounting a cargo box.
LandingPad 1, # Y00221
Yakima Control Towers, # Y00214
CrossBars, # Y00409
With these parts installed, you could then mount the box. I have included a link to the installation details for the cargo box for you to view.
