Default Title

The SHIROKAI Ford Mustang S197 ducktail spoiler gives your 2005–2009 Mustang a sharper, more aggressive rear profile that stands out on the street and at meets — and it makes a perfect first step toward a full Ford Mustang S197 widebody kit build.

Ford Mustang S197 Ducktail Spoiler Fit & Style

Crafted for precision on the 2005, 2006, 2007, 2008 and 2009 Ford Mustang, this ducktail mounts cleanly to the trunk line and follows the unique rear end of the S197 closely. Durable materials, inspected for quality — no gaps, no rattles. The mustang duckbill shape channels classic muscle cues with a modern edge.

Installation

Installs on top of your trunk — no modifications needed for most stock trunks. 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.

Performance & Finish

Aerodynamics improve with reduced lift for better stability at speed — style without giving up function. The finish resists fading and weather damage, stays easy to clean, and is ready for paint. Built for regular use, mile after mile.
