The Thule Aeroblade and Rhino-Rack Vortex bars both feature noise reducing strips that makes them almost silent in many applications.All shipments must be Canadian bound only. The new aero foil cross bars provides a significant improvement in roof rack noise. And it's a fraction of the price of a new profiled bar. The system connects to the roof of your Tacoma using the stock mounting. This does an amazing job of bringing down the noise. The Rhino Rack Backbone 2 Base Mounting System is a complete dual-rail system. If you want to go low-tech, try wrapping some bungee cord in a spiral around your cross bars. In many cases the padding also reduce side to side movement. An added benefit is that the pads serve as protection when strapping surfboards, SUPs or any other flat piece of gear to your roof. Wrapping the cross bars in pads also disturbs the airflow over and around the bars thereby reducing the humming or whistling noise from a naked roof rack cross bar. This helps reduce windnoise significantly.īut what about a square or round bar? We recommend using padded cross bar pads. Most of the premium racks comes with some type of textured rubber insert that disturbs the airflow and breaks up the frequency of the Aeolian noise we mentioned earlier. ![]() Using a wind fairingwill definetely help in reducing wind noise, but let's face it, it's just another piece of flimsy kit that gets in the way of loading and unloading your gear.

The secret to reducing the noise from a roof rack is by either diverting or disturbing the airflow around the cross bar. A square bar has a drag coefficient of about 1.05 a sphere is around 0.47 and an airfoil is as little as 0.04. If you compare the different shapes of cross bars, there is a masive difference in the drag coefficient between them. The higher the drag coefficient, the more noise is created. The amount of noise depends on the speed of the airflow (how fast you are driving) and the drag coefficient of the cross bar. Backbone rails connect to your factory mounting points with included hardware. If the surface the wind passes over has a consistent shape, the disturbance becomes tonal and at certain frequencies very annoying. 4 Pack Rhino Rack The Rhino-Rack Backbone system lets you mount a Pioneer platform rack on the roof of your vehicle. ![]() The wind noise we hear from some roof racks is known as Aeolian no ise and is produced by wind when it passes over or through objects.
