2015–Present Dodge Challenger SRT Add-On Rear Diffuser

Gloss Black Rear Detail
Built for a Stronger Challenger Finish

The lower rear bumper helps define how aggressive the Challenger looks from behind. This SRT Add-On Rear Diffuser adds sharper lower-bumper detail to the 2015–Present Dodge Challenger, giving the rear end a cleaner and more performance-inspired muscle-coupe appearance.

Designed as an add-on rear diffuser, this piece enhances the lower bumper area without replacing the full rear bumper. The gloss black finish adds strong contrast around the rear lower section, helping the Challenger look more complete, sharper, and street-ready from the back.
