Our rear Charger diffuser will fit the 2015 to 2021 RT/SXT standard body, and the SRT/Hellcat/Scat Pack body. This product is made of 1/4 and 3/8 HDPE and 14 gauge Aluminum. 

Our diffuser does work! Unlike many out there, it has the 5 to 10 degree slope to our added rear belly pan and 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 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.
