Go Rhino’s XRS Xtreme Rack features 4-CORE technology for unlimited ways to haul overland cargo and mount trail gear. 4-CORE is an extruded track system of slotted bars that can accept any 1/4 Inch-20 hex bolt which means almost any accessory can be bolted to the rack. The combination of steel and aluminum offers both strength and weight savings and can easily support OE roofop tents. Installation is drill-free and works with both factory bed rack mounting systems as well as the included bed rail mounting clamps. One Accessory Gear Plate is included. A large family of XRS and 4-CORE compatible accessories are also available to cover all your overlanding and camping needs, such as Quick Release Rooftop Tent Brackets, fold-down Accessory Gear Table, and much more.
