This is our new Diffuser for the 15-21 Challenger across all models. This products comes with an aluminum belly pan to smooth and diffuser the air coming out from under the car that is attached to our HDPE material with an automotive finish that is visible. This product is made to work using the 5 to 10 deg angle of slope from our added rear belly pan to diffuse the air properly. Comes with all mounting hardware.
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 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.
