ARB's BASE Rack mount kit for the Land Cruiser 250 uses proven attachment methods to keep the roof rack as close as practical to the vehicle roof. It includes a wind deflector and idoesn't impede the rear OE mounted antenna. BASE Rack specific blade brackets suit the 72 x47 (PN 1770010 OR 72x51 (PN 1770030) BASE Racks. 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 Jack mounts, rollers, recovery boards and even a BASE Rack custom light bar. ;
