      Description

      Leveled Up Audacity. Level up your ride’s rear-end style to audacious new heights with the HDPE Rear Diffuser in Matte Black. This rear diffuser features angular fins on its center and side sections each mounted on specially designed support plates. This design gives your rear end an aggressive race car profile that’s sure to make your fellow motorists notice. This rear diffuser isn’t just about style as its resilient HDPE construction gives the assembly enough strength to improve your ride’s aerodynamics by increasing downforce. The result is a better handling Mustang, particularly at high speeds and when cornering.

      Resilient Build Quality. This rear diffuser assembly starts out as 1/4-inch thick plates of premium HDPE material, offering outstanding strength without the extra weight. These HDPE plates are then precision-cut to computer-generated designs for an accurate fit when installed. Finally, this diffuser is available in an eye-catching matte black colorway that complements your ride’s factory rear diffuser.

      Convenient Install Procedure. Installing this rear diffuser is a relatively convenient procedure since the assembly includes pre-drilled mounting holes that work as a template for its attachment points. You will need to assemble this diffuser before installation and you will also need to drill into your factory diffuser with the included self-tapping screws. Also, installation is completed using just standard hand tools and the included hardware.

      Application. This HDPE Rear Diffuser in Matte Black fits all 2015-2017 Ford Mustang GT, EcoBoost, and V6 models.
