Modern Aggressive RTR Styling

Install the same exact Rear Diffuser that is featured as original equipment on the Ford Mustang RTR to your very own late model muscle car. Designed and developed by Vaughn Gittin Jr., this Diffuser will add a modern, yet aggressive race inspired appearance to your ride.

Quality Construction

RTR manufactures its Diffuser from OEM quality, high-pressure injection molded, high-strength thermal plastic olefin (TPO) for its long-lasting durability. This RTR Rear Diffuser features a grained texture for an OEM look and to hide rock and stone impacts that occur during daily driving.

Straight Forward Installation

Installation of the RTR Rear Diffuser is simple and straight forward. However, it will require permanent modification to the stock rear bumper cover to remove the factory diffuser. Installation can be completed in about two hours.

Backup Sensor Compatible

This RTR Rear Diffuser can be installed on Mustangs equipped with or without factory-installed back-up sensors and will not affect sensor operation.


This RTR Rear Diffuser is specifically designed to fit 2015 - 2017 GT and EcoBoost Mustangs equipped with the factory Premium Chassis Packages only (Trim Levels: 200A/201A/400A/401A).

    2015 Mustang GT RTR Diffuser

    The RTR Diffuser was very easy to install and only took about 2 hours. There is some cutting involved so make sure your ok cutting the bumper up. But after the RTR Diffuser was installed it looks amazing on my 2015 Mustang GT! As always the products from RTR are top notch and match the factory ford parts very well.
