The Shakedown package is new for 2018 and available only on Challengers with the shaker hood scoop. These include the R/T Shaker, R/T Plus Shaker, and 392 Scat Pack Shaker. Just like on the concept, the stripes are all to one side and wrap around the hood scoop. The only difference is that they're all one color, whereas the '71 custom car had one stripe in red. In addition to the stripes, the package adds white-face gauges and an upgraded Alpine audio system. On R/T and R/T Plus models, this system has six speakers with a 275-watt amplifier, while the system on the Scat Pack has nine speakers with a 506-watt amplifier.
The cost of the Shakedown package is $995, and it's available with any color of Challenger Shaker.
And on the topic of colors, Dodge has also revived Plum Crazy and B5 Blue for 2018 Chargers and Challengers. Those colors will be available on any Charger or Challenger regardless of trim level.
