Go Rhino’s XRS Cross Bars allow you to mount a rooftop tent on your truck while preserving the utility and capacity of your factory truck bed. The corner uprights elevate and support the 4-CORE cross bars approximately six inches above the factory bed cap, which provides for unobstructed access to the truck bed. Mounted tents and cargo boxes will sit below the roof of the cab, which reduce wind resistance. Each 4-CORE cross bar works with standard ¼-20 hex head bolts which allows unlimited mounting options for gear, trail tools and all your toys. Installation is easy with no drilling however cutting is required on midsize trucks. XRS Cross Bars come with a Limited Lifetime warranty on materials and construction and a 5 year warranty on the Textured Black Finish.
