Rack-it 101 Series
Aerodynamics OF WIND NOISE
We Design Racks that Look and Sound Great
WIND 101 and why bigger is quieter
Each rack has an overhang section that cantilevers out over the truck’s cab. We specifically build our overhang lengths for Standard Cab, Extended Cab and Crew Cab applications at a distance set out over the windshield to allow wind to travel up off the windshield and release through the rack. If / when an overhang is recessed above the roofline of the truck’s cab, the wind will roll off the windshield and hit the front bar, deflecting down to the roof and causing wind noise. This can come in the form of a light wind, a hum or even a massive howl depending on how far the overhang sits back on the cab. Typically, this wind noise is exaggerated at freeway speeds.
We did our Homework
We need to be clear, adding a rack to a truck automatically disturbs the meticulously engineered aerodynamics of the vehicle. Those meticulous engineers in Michigan spend hours and hours in wind tunnels trying to insure the quietest ride for your customer’s truck. Now, you’re selling your customer a product that will disturb that aerodynamics. With that being said, all cabs are sized and shaped a bit differently and we have done our homework and due diligence to make sure with our overhang lengths, we offer one of the quietest rides out there.

REMOVABLE CROSS BAR
move the Noise AWAY
A couple last points on wind noise relating to our accessory items. First, many users, especially those with an extended or crew cab overhang like to use a cross bar in the overhang to help break up the long span. These cross bars can increase the presence of wind noise so in most cases we recommend a removable cross bar so that they can be located to another section of the rack while not in use, thus limiting the wind noise opportunity.
