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.. ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks with CDEV are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. These shocks are configured specifically for each application in both length and damping tune. For piggyback and specific remote reservoir applications, ICON'S unique use of a 6061 billet aluminum manifold a few inches below the top cap of the shock creates an internal Bump Zone that when used creates an additional 20% of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity. Like all ICON'S Shock Absorbers, V.S. 2.5 Aluminum Series shocks with CDEV are 100% rebuildable and 100% revalveable.. ICON VS 2.5 Aluminum Series shocks are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. They feature remote reservoirs with CDEV and are 100% rebuildable/revalveable.. ICON's CDE Valve technology allows for in vehicle adjustment of compression damping settings and active adjustment via the ICON Intelligent Control (IIC). One-piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road. TECH NOTE: Vehicles equipped with Kinetic Dynamic Suspension System (KDSS) also require ICON rear track bar part numer 54200. ICON’s internal “Bump Zone” increases damping by 20% to provide more control as the shock approaches full compression. One-piece, hard anodized, impact extruded aluminum cylinders offer excellent corrosion resistance and consistent finish. TECH NOTE: Also requires installation of IIC kit (Part # 53504) and CDEV front coilovers (Part # 58747E). Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range. Remote reservoir design improves heat dissipation to reduce shock fade during prolonged use. ICON 2010+ Toyota 4Runner 1-3in Rear 2.5 Series Shocks VS RR CDEV - Pair.
