The all-new DiabloSport Suspension Controller is the simplest upgrade to instantly improve your suspension system in your Hellcat or SRT vehicle equipped with active suspension modes. The Suspension Controller replaces your factory controller with a simple Plug-N-Play installation. The upgraded calibration featured in the DiabloSport Suspension Controller improves handling and traction across the board by controlling the OEM shocks electronically to optimize them with performance in mind. The changes are instantly noticeable as the shocks will feel much more linear and predictable. With reduced understeer and improved handling, your car will feel planted and handle anything you throw at it, whether on the highway or the track. The DiabloSport Suspension Controller will only work on vehicles equipped with active mode suspension. Hellcats, Redeyes, Demons, and most SRT packages will include active suspension modes. *NEW SUPPORT* DS1000 now covers Trackhawk and Durango Hellcat models!
