This is our new winged diffuser for the 15-23 Challenger that will fit across all models. Designed with an aluminum belly pan to smooth and diffuse air coming out from under the car along with an additional wing to provide added down force and attached to HDPE material with an automotive finish.

This product is functional and will diffuse the air properly from the differential to the rear of the vehicle unlike other brands. Our product is designed to bolt up to the factory valance as an addon. Comes with all mounting hardware.

Additional down force will be noticeable at 75+mph and will provide a more planted feel for the vehicle. Compared to our standard Challenger diffuser, this product is 1.75" taller in a fin to fin comparison.

Product Update: This product will ship hardware that will work with a unthreaded or threaded rear differential cross brace. Please verify if you have threaded or unthreaded rear differential crossmember. If your rear end is unthreaded you will need a Rivnut Tool to install the hardware nuts that the bolts will screw into.

If you have lowering springs and or airbags, be warned this product hangs low and will scrape when taking on sharp angled instances.
