The Headache Rack combines functionality with style. It's engineered with a tapered design that matches the contour of the cab providing window protection from large cargo being hauled on top of the cover. It attaches directly to the DiamondBack cover with stainless steel bolts, so there's no drilling into your GMC.

No one enjoys drilling into their DiamondBack. With Base Track Installation, DiamondBack installs the tracks of your chosen rack system at the factory. You'll save yourself time and possible headaches knowing your tracks are installed correctly. Enjoy the outdoors instead of spending time installing the tracks on your DiamondBack.
*Tracks are not installed on the center panel of your DiamondBack.
