Show original supplier description

The American Modified SXT Style Rear Diffuser provides an aggressive, track-inspired aesthetic for your Dodge Charger. Its aerodynamic design aims to increase downforce, contributing to improved stability and handling at higher speeds, particularly during cornering. The flexible yet durable construction helps resist damage from minor impacts. This rear diffuser is molded to OE specifications for a factory-like fit and finish. It comes with a matte black surface that can be painted to match your Charger's factory color, offering customization options. However, some drilling is required for secure mounting, and painting is recommended before installation for optimal results. This SXT Style Rear Diffuser is specifically designed to fit 2015-2018 Charger R/T models and 2015-2023 Charger SE and SXT models. It is noted that this diffuser requires aftermarket round exhaust tips for proper fitment.
