mopar part# 82213979ab fits 300, charger, challenger. Shows it fits 2019 challenger hellcat, 2016 charger hellcat. Frames are same thru 2020. There is a disclaimer to not exceed owner manual recommended weight limits. These cars do have rear frame rails up above the rear mufflers, you have to fish the bolts thru, no drilling. My son in law put one their 5.7 charger, long after warranty.
