ARB43 AeroBlade Load Bar Pair Features WindDiffuser™ is a textured surface on the t-slot cover that disturbs the airflow better than a smooth surface, greatly reducing wing noise. BoxBeam™ - The sophisticated Box Beam aluminum extrusion creates one of the strongest load bars in the market. Using a vertical load test, the AeroBlade can sustain over 800 lbf of force. SmartSlide™ – The new SmartSlide™ is a molded measurement system providing a quick, no-hassle, tape measure-free foot installation. SmartSlide™ also covers the underbar slot to improve aerodynamics and noise diffusion.
