Rear Bumper Diffuser Lip

Rock Style rear styling for 2018-2023 Ford Mustang EcoBoost and GT350 applications

Product Overview

Give the lower rear bumper a more aggressive stance with this NINTE rear bumper diffuser lip. The sculpted Rock Style profile sharpens the Mustang's rear appearance and helps redirect rear underbody airflow into a cleaner linear path. Flexible polypropylene construction and a black exterior finish make it a practical styling upgrade for compatible vehicles.

Critical Fitment and Exhaust Warning

This diffuser is only for compatible 2018-2023 Ford Mustang EcoBoost and GT350 applications equipped with the required dual-exhaust pipe configuration.

Do not order for a vehicle with a different exhaust arrangement, rear bumper shape, or mounting layout. Compare the vehicle year, model, bumper profile, exhaust outlets, and attachment locations before installation.
