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.

Simple, easy install despite the Thule useless instructions. Nice clean look on the car. etrailer.com was great to work with, although they could cut down on their packaging. The shipping box was huge relative the Thule boxes it contained. I made use of it, and it got repurposed, so all is good. 652754

Hi, I was wondering if there is an accessory to correct a 3/4-inch drop from the front to the back bar? See photos. Thanks. 697057


Comments
The slope that you are seeing is due to the profile of your vehicle. I have confirmed with my contacts at the manufacturer and there are no adapters available to level out your roof rack. As long as your lumber is secured properly you should not have any issues.

Attached are some photos of the product crossbars mounted on my 2014 Cherokee. I love the product but have not figured out how to remove without damaging the plastic screw where a lock would be. Probably need to purchase the locks to replace the plastic screws. Product worked beautifully and I am very satisfied with my experience with etrailer.com 138756

I was looking for a low profile roof rack for my new Kia Telluride. These fit the bill perfectly. Look great, and are just high enough for the sunroof to still open. Easy install! Once out the door from eTrailer shipping was fast. 849355

Review from a similar AeroBlade Edge in Roof Rack


The roof racks are of great quality, what you would expect from Thule. The only disappointment was the directions. They were the picture only style with not a clear picture of all the parts, or how to attach them to the roof rails on the Lincoln. We are extremely handy people(we have built kitchens baths ect. )These racks were a good 2 hour project due to the poor directions, and then another hour to attach our Thule kayak racks. Hopefully the ski racks will go on easier!! All in all once installed they look good, have a clean line and don't detract from the car. 414768

Review from a similar AeroBlade Edge in Roof Rack


I was concerned about the fit given that the dealership said this unit would not fit this car with a sun roof. I discovered etrailer during my search for more fit up information. etrailer had better information than even Thule. As a bonus, the cost was lower than other sites I visited. The materials were as advertised, well packaged and shipped on time. The fit and quality of the Thule racks was great. Very sturdy build and easy to install. Very happy. 494795

These crossbars for the factory side rails fit our 2014 Mazda CX-5 perfectly. I chose this style because I did not want anything hanging over the side where I can bump my head getting in and out of the car. The fit gets snug if you try to put the rear rail all the way at the end of the side rails, indicating the side rails are closer together at the back than the front. I was trying for maximum spread since I'm carrying a 17 foot kayak. They work well, look good and are quite sturdy. 157077

Easy to install on my 2019 Hyundai Santa Fe, even for a non-mechanically oriented person like myself. Very solid. Does NOT interfere with panoramic sunroof as some warnings had mentioned. Haven’t taken it on the road yet, but expect it to be quiet based on other reviews. etrailer.com shipping was fast - received in just one and and a half days. The installation video on the site was very helpful...better than the included written instructions. Highly recommend this rack and etrailer.com. 640909

First of, etrailer.com did an awesome job in shipping these out fast. Very pleased & impressed. About the roof racks, these things are awsome. They look great (best I've seen from any manufacturer), installs easily and appear well built & very sturdy. Already went on a road trip carrying a loaded XXL cargo box. No issues at all. Again, very happy with the purchase. 138313

Quick delivery and very happy with the quality of this . Instillation was simple and the end result looks and feels very sturdy. I went for a test drive up to 75 mph and had zero wind noise with the windows and sunroof open. Can't wait to put up the canoe and hit the lake with family. Thank you etrailer! 264754

First class customer service, will do business with etrailer again. Rack installed on my 2014 Jeep Grand Cherokee in about an hour. Now that I know what I'm doing, I can do it in 10 minutes. Thule picture directions are useless, check YouTube. Rack looks good, I like the look on my Jeep. Have yet to endurance/speed test. 103840

ordered these bars for my 2018 Highlander for a Thule force XL, they fit GREAT and the look is sweet! now I need to get some same key locking cores for everything but these are top notch! Never dreamed I would spend a grand on a roof box and bars, but with my family of 5, and the lack of cargo space in the HL it's GREAT! We came from a 2008 Escalade ESV with TONS of space but got sick of the TANK! 485234

Superb Customer service. Prompt shipping. Actually shipment got to my home a day earlier than I was expecting. Product was packaged in oversized box with plenty of padding and protection. Only complaint, (not that it's major) but there were absolutely no instillation instructions with product. IF someone has any mechanical skills they can figure it out, but always good to know your installing properly. Installed withing 15 minutes on my 2016 Ford Flex. 303293

Wow !!!! Excellent service and very fast shipping. I bought the Yakima Megawarrior cargo basket with the Thule Aeroblade roof rack and the Carpod walled folding cargo basket. I love the way these parts fit as well as the cargo carrying capacity. I really can’t say enough about trailer customer service and shipping they really do place value in their customers. Would highly recommend using this company for your part needs !!! 529598

etrailer provided great shipment/notification support. Little more than trivial to install Thule AeroBlade onto 2021 Mazda CX-9, but etrailer was great resource for how-to videos that were key to successful install. Quality materials and convenient design. No significant noise noticeable from wind resistance when driving. 933283
