Give your Challenger a bolder rear profile with the AAD V2 Rear Diffuser. Its shark fin design adds definition to the lower rear bumper, while the matte black finish delivers a subtle contrast that complements your exterior upgrades.
Made from polypropylene (PP), this diffuser brings an aggressive look to your build without the shine of a gloss finish.
