Our rear Challenger Stealth diffuser will fit all* 15-23 standard body 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. Our product is designed to bolt up to the factory valance as an addon.  Depending on your mufflers you may need to trim the aluminum pan to fit.

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.
