The all-new DiabloSport Suspension Controller is the simplest upgrade to instantly improve the suspension system on Hellcat or SRT cars equipped with active suspension modes. The Suspension Controller replaces the 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 customer's car will feel planted and handle anything they can throw at it, whether on the highway or the track.
