Give your Challenger a more aggressive rear profile with this IMP-style rear diffuser. Sculpted shark fins, a gloss black finish, and an integrated center LED accent create a bold look that complements the car’s muscular styling.
Designed to replace the factory rear diffuser, it adds a distinctive finishing touch to your rear bumper.
