This trim fits the Prinsu Roof Racks front wind deflector. It limits the amount of wind that can travel between the roof and bottom of the wind deflector thereby reducing the wind noise.
Noise reducing edge trim for 2nd & 3rd Gen Tacomas, 4th & 5th Gen 4Runners, Lexus Gx460 & GX470 Series, and Chevy Colorado Roof Racks
