The BASE Rack takes accessories and cargo loading to a whole new level of simplicity, speed, and personalization. The BASE Rack is fully-welded aluminum for lightweight strength that doesn't flex under load. It can therefore be mounted close to the vehicle roof for a slimline aesthetic and reduced drag. Its dovetail extrusion attachment system runs the full perimeter of the rack and along each internal beam providing endless mounting and attachment options. Adding, removing, and repositioning accessories and roof loads is quick and easy, and individual items may be installed or removed without disturbing the whole load. Unlike traditional roof rack channels, the BASE Rack dovetail system doesn't collect dust and debris. This kit includes a 72 in (L) x 51 in (W) BASE Rack and mount kit with wind deflector to suit the Toyota 4Runner. The longer rack allows for more storage space and ability to distribute the weight more evenly.
