Using the proven internal frame for ARB’s classic style roof racks as the basis, a BASE Rack specific mount kit has been developed for the Jeep Wrangler JL Unlimited fitted with the factory hardtop. Internal bracketry is carried over from the previous kit with BASE Rack specific blade brackets developed to suit the 61″x51″ PN 1770020 BASE Rack. The BASE Rack takes accessories and cargo loading to a whole new level of simplicity, speed and personalisation. With a choice of sizes, accessories and attachments, you can truly Make It Your Own. By incorporating a dovetail extrusion around both the full perimeter and along each edge of the internal beams, the BASE Rack provides endless mounting and attachment options. Adding, removing and repositioning accessories and roof loads is quick and easy with the BASE Rack’s dovetail system, making it easier to install and remove individual items without disturbing the whole load. Plus, unlike traditional roof rack channels, the BASE Rack dovetail extrusion won’t collect dust and debris. Each BASE Rack accessory or fixture attaches to the rack with a simple clamp mount, including larger hardware such as Hi-Lift(TM) Jack mounts, rollers, recovery boards and even a BASE Rack custom light bar.
