This is the winged diffuser for the 15-19 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 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.

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.

Warning: This product will touch the ground on steep slopes and driveways on a stock height Challenger, this product is meant to be functional and close to the ground. If you have lowering springs and or airbags, be warned this product hangs low and will scrape when taking on sharp angled instances. 

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.
