Does it fit my truck?

It is listed for the 2015–2020 Chevy Colorado and GMC Canyon. Check your model year before ordering.

Does it work with the windows up?

Yes. The deflector sits in the channel and the window closes against it. Keep the channel clean so the glass seats fully.

Will it block my view?

The smoke acrylic is see-through, so visibility through the side glass stays clear.

The flanged edge goes into the window channel and 3M automotive tape holds it. No drilling is needed.

Can I use a car wash with it?

Yes, but avoid high-pressure spray aimed directly at the deflector edges, which can loosen the tape.

About the Westin 72-39923 Matte In-Channel Wind Deflector 4pc

These in-channel wind deflectors reduce wind noise, heat and glare. Fresh air still comes in when the windows are rolled down slightly. They redirect the air up and into or out of the vehicle, which lowers its volume and strength.

Each deflector is made from smoke acrylic that is transparent, so visibility is not obstructed. To install, insert the flanged edge into the window channel and secure it with 3M automotive grade tape. The set includes 4 pieces.
