ICON's exclusive Compression Damping Electronic Valves are included for actively dialing in your suspension performance and improve upon the functionality provided by the factory active shock system. Compression Damping Electronic Valve (CDEV) is an electronically controlled valve that meters the flow of oil to regulate the amount of damping force that is created by the shock when compressed. This infinitely variable valve can react in less than 40ms and has the ability to make extremely precise adjustments for varying terrain. CDEV’s hydraulic circuits are also custom tailored per application to create the highest resolution and dynamic range allowable for each specific vehicle. Powered by ICON Intelligent Control (IIC) and proprietary ICON mobile app, the system uses information from the onboard G-force sensor and Gyroscope to perform calculations based on algorithms and user-defined settings to predict terrain and adjust shock settings via the CDEV accordingly. With the shock absorbers no longer directly wired to the Raptor's ECU the IIC/CDEV system also allows drivers to dial in their preferred shock damping settings independently from the selected vehicle drive mode and with more refined resolution than afforded by the factory system. This allows for a more customized vehicle set up with the perfect blend of comfort and performance.
