Description
ZL1 Addons’ Rear Diffuser for 2015–2023 Dodge Charger is engineered to fit both RT/SXT standard body vehicles and SRT/Hellcat/Scat Pack body vehicles. Built from ¼– and ⅜-inch HDPE paired with 14-gauge aluminum, this diffuser is functional, not cosmetic, and is designed to properly diffuse air from the differential to the rear of the car for improved underbody airflow.
The diffuser bolts to the factory rear valance as an add-on upgrade. Depending on your muffler setup, minor trimming of the aluminum pan may be required.
Rear Cross-Brace Hardware Update
This diffuser now ships with hardware compatible with both threaded and non-threaded rear differential cross-braces.
-
If your brace is unthreaded, you will need a Rivnut Tool to install the hardware inserts.
