Kargo Master racks are designed to minimize wind noise, but sometimes cab lights, atmospheric conditions or other accessories can cause noise. This wind deflector bolts to the front crossbar, and can be positioned to optimally deflect wind up over the cab, reducing or eliminating noise. Especially recommended when standard length racks are mounted on extended cab trucks. It routes wind coming off the windshield up over the cab to reduce wind noise. Fully adjustable. Black only
