Upgrade the rear styling of your 2018–2023 Ford Mustang EcoBoost or GT350 with the Classic Edition Rear Diffuser. Designed to give the S550 a more aggressive and performance-focused appearance, this diffuser enhances the lower rear bumper with deeper contours and a cleaner, more muscular profile.
Featuring a vehicle-specific design that complements the factory rear bumper, the Classic Edition Rear Diffuser creates a wider and more planted appearance while maintaining a clean OEM+ look. Its sculpted fins and performance-inspired shape make it an ideal upgrade for street, show, and modified Mustang builds.
