Default Title

Sharpen your rear with the SHIROKAI Ford Mustang S550 ducktail spoiler for 2015–2022 models — a bold, aggressive look that follows the natural shape of your Mustang. It also makes a perfect first step toward a full Ford Mustang S550 widebody kit build.

Ford Mustang Ducktail Spoiler Fitment & Style

Designed for a precise fit on 2015, 2016, 2017, 2018, 2019, 2020, 2021 and 2022 Ford Mustang S550. Built from high-quality materials — strong, lightweight, and shaped to match the bodylines for a clean, purposeful finish. A distinct, duckbill-inspired look without losing the car’s original character.

Installation

Installs on top of your trunk using factory mounting points. You may need to drill a few holes and use double-sided tape and/or rivnuts. Easy install in 30–60 minutes with the right tools. The smooth finish is ready for paint.

Performance & Pairing

More than looks — the ducktail adds downforce for better grip and stability at speed, great for street and track. Pair it with our S550 widebody kits for the full build: the 2015–2017 S550 kit or the 2018–2023 S550 kit. Take your Mustang’s exterior to the next level.
