The AeroBlade Edge

This single Thule AeroBlade Edge crossbar lets you replace a damaged crossbar or add another crossbar to your existing roof rack to help distribute the weight of a load on your roof. The crossbars mounts directly to your vehicle's elevated, factory side rails to create a roof rack that is quieter, stronger, and more aerodynamic than almost anything on the road. The low-profile, arced shape of the crossbar couples with the unique WindDiffuser stripping to produce a bar that is so quiet you'll forget you even have it on your car. Many factory and aftermarket bars produce an annoying whistle that can only be quelled by adding a fairing to the system. Not only is a fairing unnecessary with the AeroBlade Edge, but adding one would actually make it louder and less aerodynamic.

WindDiffuser Technology

A built-in T-track sits along the top of the bar, near the front. When no accessories are mounted, the included WindDiffuser rubber stripping covers the T-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 stripping 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 Edge, is the raised, angled vectors (or ribbing). This textured surface disrupts and redirects the air flowing over the bar, tripping it to create turbulence and clean air release. The result is less wind noise and drag, little to no annoying whistle, and a more aerodynamic crossbar. In fact, the AeroBlade Edge crossbar has been shown to produce 90 percent less sound energy than an elliptical Thule Aero bar, making it the quietest style of load bar in the industry.

Aerodynamic Design

Thule took a note from the manufacturers of high-performance cars, such as Ferrari and Maserati, and designed the AeroBlade Edge 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 Edge load bar is constructed of extruded aluminum to ensure an extra-sturdy roof rack system. During the extrusion process, metal is shaped to form a complex BoxBeam design on the interior of each bar, as seen in the cross section of the AeroBlade Edge. Each fold adds to the overall strength and rigidity of the bar. This process creates a crossbar that is primarily hollow but still reinforced for added strength. The result is a bar that can withstand more than 800 lbs of force, yet weighs so little that it takes up only a slight portion of your load capacity.

AeroBlade Edge Installation

The mounting style of the AeroBlade Edge offers the most surface contact of any side-rail-mounted crossbar, ensuring that the roof rack is solid and secure. To install the bar, first measure the diameter of your roof rack side rails. There are 4 notches in the rubber-coated steel mounting straps to accommodate side rails of different sizes. Once you determine the appropriate notch to use, remove the crossbar covers and connect the straps to the feet. Wrap each strap under and around the side rail, and snap it into place on the posts at the top of the foot. To complete installation, use the included tool to tighten the straps around the bars until they audibly click and then replace the crossbar covers.

Mounting Roof Rack Accessories in T-Slots

Mounting roof rack accessories is quick and easy with the AeroBlade Edge. Simply remove the crossbar cover, slide in your accessory, and replace the cover. Some accessories may require Xadapt hardware (sold separately), and trimming of the WindDiffuser strip may be required to accommodate accessory mounting hardware. To deter theft of your carriers - and the crossbar - add Thule One-Key System lock cylinders (sold separately) to the covers.

Video Transcript for Thule AeroBlade Edge Roof Rack Installation - 2014 Dodge Journey

Today on our 2014 Dodge Journey, we'll be test fitting the Thule AeroBlade EdgeRoof Rack System using part numbers TH7503and TH7502. We'll grab our front bar, which is the TH7503and place it onto the front part of our siderails. To make sure that our feet are going to be in line with each other, we need to find a fixed point on each side rail. On each specific side rails, there's hashmarks that run up and down the side rails. Once we have them placed, we can remove the black plastic cover and install our strap. Now on each end of the strap, you'll notice that one end has four slots and the other end has two slots for the mounting points.

The end with the four slots is the end that will go in the foot pack around the underside of our load bar. The four holes are to accommodatethedifferent size of side rails that we may have. Here on the front, I'll be using slot number three. Now we can use the included hand tool to make our way back and forth tightening it a little at a time. One of the great feature of the Thule AeroBlade Edges is that when we have our straps secured, we'll hear a clicking noise.

Once we have it tight, we can replace the black plastic covers. We'll grab our rear bar and place it onto the rear part of our roof. Again, we'll use the hash mark indicator on the side rails to make sure that our feet are in line. For the rear, we'll be setting our straps on slot number two. We'll bring the straps around, fit it back into end of the carrier, and then we can repeat the same tightening process that we used at the front.

Once we have it tight, we can replace the black plastic covers and we're ready to go. Please keep in mind that we need to have a minimum load bar spread of about 24 inches. That completes today's test fit for the Thule AeroBlade Edge Roof Rack System using part numbers TH503 and TH502on our 2014 Dodge Journey. .
