When you sport a Chrysler, Jeep, or Dodge with a Hemi under the hood, you should be proud of the power you have. But, in order to save on gas your Hemi is designed to cycle down to just half of your cylinders at a time. But now you can keep firing on all cylinders at all times with the  Range Multiple Displacement System Manager.

Your Range Multiple Displacement System Manager allows you to avoid the sluggish moments in your Chrysler, Jeep, Dodge, or Ram. By keeping your Hemi running on all eight cylinders at all times, you’ll find the additional power you need to conquer snow, steep hills, mud pits, and more! Because power is divided even at a light throttle, you can actually see improved fuel economy overall.

The plug-and-play installation couldn’t be easier. Just pop the device into your OBD-II port and you’re ready to go. Removal is just as quick and easy, and your Hemi-equipped vehicle will automatically revert back to factory settings. Backed by a 1-Year Warranty.
