Yakima's SkyLine FX Car Roof Rack is designed to install on vehicles with fix-points, factory racks, factory tracks, permanent mounts for fiberglass pickup truck caps, and permanent custom mounts. With the Yakima SkyLine FX Car Roof Rack, the JetStream bar does not extend beyond the SkyLine FX Foot. Yakima SkyLine FX's snap-fit design provides an easy-to-use, solid, secure fit to your vehicle. With BarBed Pitch Adjustment, crossbar pitch can easily adjust to keep crossbars level on vehicles with curved roof-lines. A pre-calibrated torque driver is included to assure the exact tightness level during installation. Yakima SkyLine FX Car Roof Racks are sleek, quiet, attractive, strong, custom fitting, aerodynamic and look as good as they function. The SkyLine FX features a push-down infilled t-slot for maximum noise reduction. Simply push down the rubber insert and fasten your accessory into the t-slot. Other carriers designed to fit factory racks, such as Yakima Ski and Snowboard Racks can also be mounted on the FlushBar. The width between the towers can be precision adjusted for your vehicle and snapped in place along the bottom of the cross bar.
