      Aggressive Shelby GT500 Styling. Revamp the exterior styling of your S550 Mustang with this GT500 Style Rear Bumper and Diffuser Kit from MP Concepts. MP Concepts Rear Fascia and Diffuser closely mimics the styling of the Shelby GT500 to give your base model Mustang a more aggressive appearance with its polished quad exhaust tips.

      Complete Kit. MP Concepts Rear Fascia Kit comes complete and includes the rear fascia, lower diffuser, LED reverse light and a pair of polished quad exhaust tips. The Kit does not include Side Markers – these will all carry over from your Mustang.

      Quality Construction. MP Concepts manufactures their Rear Bumper Cover from OEM quality Polypropylene. Polypropylene is an extremely strong and durable thermoplastic polymer, making it perfect to withstand the hazards of daily driven vehicles. The Diffuser is also made from Polypropylene and features a slight black stipple textured finish for an aggressive appearance, superior durability and light weight.

      LED Reverse Light. The included MP Concepts Smoked LED Reverse Light replaces the weak stock incandescent reverse light with super bright white LEDS for increased rear visibility. While a uniquely designed, integrated fourth brake light helps to make sure you are clearly seen by distracted drivers when you apply your brakes.

      Straight Forward Bolt-on Installation. MP Concepts engineered their Rear Fascia Kit to be a direct fit upgrade replacement for your original stock bumper. Installation can be completed in about two hours, after painting of course. Please note that some of your original hardware will be reused for installation.

      Not Prepped for Backup Sensors. This MP Concepts GT500 Style Rear Bumper is specifically designed for Mustangs that do not have factory installed back-up sensors. Modifications will be needed if installed on a Mustang that is equipped with back-up sensors.

      Application. This MP Concepts GT500 Style Rear Bumper and Diffuser Kit is designed to fit 2015-2021 GT, EcoBoost, V6 Mustang models.

      Technical Notes. This MP Concepts Rear Fascia Kit ships unpainted. AmericanMuscle recommends professional installation of all body parts. We also recommend test fitting these products before they are painted.
