ICON Vehicle Dynamics V.S. Series 2.5” coilover shocks are an incredible upgrade for the front end of 2021-2023 Ford F-150 4WD trucks. ICON’s Vehicle-specific valving provides a sport tuned feel on and off-road while 2.75-3.5” of lift height adjustability allows the use of larger, more aggressive wheel and tire combinations. The larger 2.5” shock body and increased piston area over stock components provides improved damping ability and outstanding ride characteristics across varying types of terrain. Remote reservoirs ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during heavy use. The ICON CDE Valve upgrade is included for those desiring an easy way to tune the ride electronically from inside the vehicle. 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 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. When paired with ICON rear 2.5 Aluminum Series CDEV shocks vehicle control will be balanced front to rear, resulting in the best overall driving experience for your F-150 truck.
