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 bars in my opinion!


I have had these bars installed on a 2011 Jetta Tdi Sportwagen for about 4 years and have had absolutely no issues at all and NO WIND NOISE! They are super quiet on my car, I don't have any noise at all actually. When installing you do have to have the rubber strips completely covering the gap where the foot pad is installed underneath the bars on each end. Maybe this is where some of the negative feedback is coming from. But I loved mine!

You will rue the day you put these on a Wrangler


If you like to be able to drive faster than 45mph in your Jeep, do not buy these. The wind noise isn't too bad, but there is an awful, awful whistle that will occurs at speeds as low as 45mph, but usually starts closer to 55mph. For that reason, I have to move the front one far back if I am not using it, which makes it quite an obnoxious rack if you use it often but not constantly. I cannot fathom the square bars being louder, and dearly regret not saving ninety bucks and getting those.

Caution-Poor Design


The rubber straps are failing after 18 months and need to be replaced. I would not have bought this product had I known that I would have to replace the straps every year. This could cause a serious accident.
