The Westin matte black in-channel wind deflectors for 2021–2024 GMC and Chevrolet Tahoe and Yukon are a four-piece set that reduces wind noise, heat, and glare while permitting fresh air flow when windows are cracked. They install by inserting the flanged edge into the window channel and securing with 3M automotive tape for a clean attachment. Their slim profile helps maintain cabin comfort across seasons without exterior adhesives.
