ZL1 Addons rear Challenger Stealth diffuser will fit all 2015-2023 models. This product is made of 1/4 and 3/8 HDPE and 14 gauge Aluminum. This product ships with the main diffuser and two rear extensions making it a 3 piece install.
This product is functional and will diffuse the air properly from the differential to the rear of the vehicle, unlike other brands. ZL1 Addons product is designed to bolt up to the factory valance as an add-on. Depending on your mufflers you may need to trim the aluminum pan to fit.
Please verify if you have threaded or unthreaded rear differential cross member. This will determine the hardware required for mounting. You MUST verify ahead of ordering. (See the install video below on where to look)
If your rear end is unthreaded you will need a Rivnut Tool to install the hardware nuts that the bolts will screw into.
