Product Overview: Beat The Elements And Add Some Attitude To Your Truck, Van Or Suv. Sidewind Deflectors Allow You To Keep Your Windows Partially Open, To Provide Ventilation To The Interior. Today's Modern Aerodynamic Body Styles With Form Fitting Doors And Windows No Longer Feature "Rain Gutters" To Channel Away Water. The Result Is Usually Water Dripping Into The Interior. Sidewinds Act Like A "Drip-Edge" For Your Vehicle, This Allows You To Keep Your Window Partially Open For Ventilation, Without The Rain Getting In. As Air Flows Around The Outside Edge Of The Sidewind It Creates A Small Low Pressure Area Underneath It (Much Like An Airplane Wing) Which Creates Suction To Keep Out The Wind And Draw Out The Stale Air From Inside Your Vehicle.Product Info:Stampede 2019 Compatible With Chevy Silverado 1500 Double Cab Pickup Tape-Onz Sidewind Deflector 4Pc - Chromematerial: Modified Acrylicstyle: Outside Mountcolor: Chromesold As: 4 Pc SetManufacturer Part Number:Part Number: 6010-8Guarantees And Warranties:30-Day Satisfaction Guaranteesee Manufacturer's Website For Most Accurate Warranty Information.
