Description
Winged Diffuser Performance. The Deluxe Diffuser is engineered as an aerodynamic enhancement for the vehicle, designed to smooth airflow from under the car and increase rear downforce. It functions by properly diffusing air from the differential to the rear, improving vehicle stability and providing a more planted driving feel at higher speeds.
Construction and Appearance. This diffuser features an aluminum belly pan combined with HDPE material finished for automotive use. The attachment plate is available in raw aluminum, showing fine manufacturing marks, or black powder coated aluminum for a sleek look. The design ensures durability while maintaining effective airflow management.
Installation. Installation bolts directly to the factory valance and includes all necessary hardware. The rear differential cross brace type should be verified prior to installation; a Rivnut tool is required if the cross brace is unthreaded.
Application. Designed to fit 2015-2023 Challenger models, compatible with both threaded and unthreaded rear differential cross braces when properly installed.
