Why Upgrade Your Chrysler 300?

The Chrysler 300 shares its rear-wheel-drive LX platform and Gen III HEMI engine family with the Dodge Charger, Challenger, and Magnum — which means it responds extremely well to proven bolt-on upgrades. Adding airflow, improving fuel delivery, and dialing in your suspension transforms how the car drives on the street and at the track. Whether you want quicker throttle response for daily driving or a track-ready setup, our Chrysler 300 aftermarket parts make it easy to build exactly what you want.
