Attach these premium, aluminum bars to Thule roof-rack feet to create a sturdy, stylish, roof-mounted rack that is supremely quiet and aerodynamic. Pivoting endcaps let you easily slide on T-slot-mounted accessories.
Thule's AeroBlade bars are designed to be among the quietest, strongest, most aerodynamic load bars on the road. The low-profile, arced shape of the bars couples with the unique WindDiffuser stripping to produce a bar that is so quiet you'll forget you even have a rack on your car. Many factory and aftermarket roof racks produce an annoying whistle that can only be quelled by adding a fairing to your system. Not only is a fairing unnecessary with the AeroBlade, but adding one would actually make it louder and less aerodynamic.
A built-in T-track sits along the top of each bar, near the front. When no accessories are mounted, the included WindDiffuser rubber stripping covers the slot. (You can also cut the stripping so that it can be placed in the slot around any carriers or accessories that are mounted.) The rubber strip serves to keep dirt and grime out of the T-slot and provides a little scratch-resistant cushion for any mounted items.
The unique aspect of the WindDiffuser, which comes standard with the AeroBlade, is the ribbing. This textured surface disturbs the air flowing over the bar, tripping it to create turbulence. The result is less wind noise, little or no annoying whistle, and a more aerodynamic rack. In fact, the AeroBlade has been shown to produce 90 percent less sound energy than the elliptical Thule Aero bars, making them the quietest load bars in the industry.
Thule took a note from the manufacturers of high-performance cars, such as Ferrari and Maserati, and designed the AeroBlade with a Kammback (or Kamm-tail) style. This crossbar does not have a full-length teardrop-type tail; rather, it is cut off, leaving a square end at the rear of the bar. The aerodynamic effect is essentially the same as it would be if the bar continued into a full teardrop shape. Air continues to move over it in a streamlined fashion, flowing along the bar as it would if the tail were complete. Because there is no tail, though, the bar is smaller and weighs less.
Strong, Durable Construction
The Thule AeroBlade load bars are constructed of extruded aluminum to ensure an extra-sturdy roof-rack system. During the extrusion process, metal is shaped to form a complex design on the interior of each bar, as seen in the cross section of the AeroBlade. Each fold adds to the overall strength and rigidity of the bar. This process creates crossbars that are primarily hollow but still reinforced for added strength. The result is a bar that can withstand more than 800 pounds of force, yet weighs so little that it takes up only a slight portion of your load capacity.
Installation of Thule AeroBlade Crossbars
To install your crossbars, use the included SmartSlide measurement system. This molded material lines the bottom slots of each bar and is scored and numbered to directly correspond with the instructions included in your custom mounting kit. By covering the bottom slots, around the feet, the SmartSlide manages to further reduce noise and eliminate whistlingas well.
Mounting accessories on your roof-rack crossbars has never been easier. With the AeroBlade you can slide accessories into the T-slots without having to wrestle off an endcap. Just pop the SwingBlade up and swing it out for instant access to the top slot.
