Roof bar

Thule AeroBlade ARB43

Aerodynamic aluminum load bars that provide an exceptionally quiet and efficient ride.



  • WindDiffuser™ is a textured surface on the t-slot cover that disturbs the airflow better than a smooth surface, greatly reducing wing noise.
  • The sophisticated BoxBeam aluminum extrusion creates one of the strongest load bars in the market.
  • SmartSlide is a molded measurement system providing a quick, no-hassle, tapemeasure-free foot installation. SmartSlide also covers the underbar slot to improve aerodynamics and noise diffusion.
  • SwingBlade™ end cap pivots open to allow full access to the t-slot for easy accessory installs.
  • The following products are not compatible with the AeroBlade: 503 Load Stops, 516 Prologue, 579XT Canoe Carrier, 558P Tandem Carrier, 597XT Hullavator, 847 Outrigger II, 870XT-873XT Fairings, 884 Roll Model

Great looking and quiet


Fantastic quality and appearance. I see some people have had problems with road noise. If that's the case then they probably forgot to cover the holes with the rubber strips provided in the installation kit. Mine don't make a peep at any speed. 2011 Subaru Impreza hatchback.

I like to camp





I am sorry that others are having issues with these bars. Maybe it's the way that the wind is coming off their vehicles. I have had nothing but a grand experience with the AeroBlades. I had round bars on my car in the past and I can say without a shadow of a doubt... These are exponentially better. The round bars had a horrible howling.. You may save a few dollars by getting the square or round bars but you'll end up spending those few dollars on a airdam to quite the round / square bars. The AeroBlades don't require an airdam. They are quite.. As they can be of course. I hame the same bars on two different cars and getting ready to move them to my third car.. I can't say enough about the AeroBlades.. On a side note... Thule warranty ROCKS IT! I had an issue with the bike trays that I bolted onto these bars and Thule CS replaced them! No questions asked once I provided the proper documentation to prove that I purchased the bike trays... They ran with it and replaced the trays! All I can say..... "Thule for life!" thanks Thule

Not Worth the money.


Nice looking bars, whistles at moderate to high speeds (the openings are covered). No attachments work with them. Stupid end caps that pop off easily and the rubber strips are a pain in the... Excellent capacity. Buy something else
