You'll love the look and performance of the JetStream Crossbars, part of Yakima's truly innovative StreamLine roof rack system. The aerodynamic shape was designed in a wind tunnel to efficiently reduce noise and drag. The premium aluminum crossbar is extruded with Yakima's JetTruss for unparalleled strength. The asymmetric JetFlow shape controls the laminar flow and maintains a thin boundary layer of air flow that results in low drag and a quiet bar. Top T-slot has a push-down infill that allows you to attach mounts while maintaining air flow over the bar. High-gloss automotive-grade polymer end caps create a sleek, high-tech look.
