Aggressive Modern Design. Make your Mustang stand out at your next car show with a set of Defenderworx Quarter Window Louvers. These stepped Louvers were designed to give your fastback S550 Mustang a more aggressive muscle car appearance. With these Quarter Window Louvers on your Pony, you are guaranteed to turn heads wherever you go.

Polyurethane Construction. DefenderWorx manufactures their quarter window louvers from industrial-grade, OEM quality injected molded polyurethane for superior strength and long lasting durability. These Louvers are completed in a matte black finish that allows them to be installed straight out of the box.

Easy Installation. No fuss, no muss installation. DefenderWorx Quarter Window Louvers are designed to attach to the factory C-Pillar glass with the supplied 3M doubled sided automotive bonding tape for a quick and easy installation. Just clean the surface, peel the backing and stick in place - it's that easy.

Recommended Styling Upgrade. When installing exterior quarter window louvers or scoops on your Mustang it is recommended to add a set of quarter window blackout decals to hide the ugly back side that wasn't meant to be seen by human eyes. See option above.

4-Year Warranty. DefenderWorx guarantees to the original purchaser of its products a 4-year, 36,000 mile warranty, against manufacturer defects in materials and workmanship under normal use. Some exclusions may apply, please see manufacturer's warranty for details.

Application. Defenderworx Quarter Window Louvers are designed to fit all 2015 to 2018 Fastback Mustangs, including the V6, EcoBoost, GT, and Shelby GT350 models. Sold as a set of two, one driver side and one passenger side.
