How to Prevent Crossbar Whistling with Rhino Rack Aero Crossbars

Question:

Hey guys I did not want to leave you a rating yet because I believe you guys can still help me make this a five-star experience. Im getting some whistling from the underside of these racks. Is there any way you can send me some more of the rubber s so I can fill those holes? I believe I need roughly about 3ft for each rack.

The bottom of the Rhino Rack Vortex crossbars do have openings in them which can cause whistling. The openings are typically due to the measurement sections that get removed for securing the bar to the feet.

Best solution is a fairing which will direct air over the bars and prevent the whistling. For that we have the part # RRRF2 which would fit well for the part # RRVA126B-2 that you have.
