ICON 57841EP 2.5 VS CDEV Remote Reservoir Rear Shocks for 2022-2023 Toyota Tundra with 3.5-Inch Lift

ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks 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. Like all ICON'S Shock Absorbers, V.S. 2.5 Aluminum Series shocks are fully rebuildable and re-tunable. 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. 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. 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. APPLICATION NOTE #397: Compatible with 3-3.5” of rear lift on non-TRD Tundras or 3" rear lift on TRD Tundras equipped with rear coil springs

• Fully rebuildable and re-tunable

Upgrade the rear suspension of your 2022-2023 Toyota Tundra with the ICON 57841EP 2.5 Aluminum Series Vehicle Specific shocks. Designed for Tundras equipped with rear coil springs and approximately 3 to 3.5 inches of rear lift, this pair of shocks delivers controlled off-road performance while maintaining a smooth, composed ride on the street. The vehicle-specific length and damping calibration are engineered to match the application for improved suspension control and ride quality.
The included Compression Damping Electronic Valve (CDEV) allows precise, in-vehicle adjustment of compression damping through ICON Intelligent Control and the proprietary ICON mobile app. The electronically controlled valve can respond in less than 40 milliseconds, using input from the onboard G-force sensor and gyroscope to adjust damping based on terrain, driving conditions, and user-defined settings. This provides a broad range of adjustment for changing trail conditions without requiring manual shock changes.
Each ICON 57841EP shock features a nitrogen-charged monotube design with a remote reservoir for improved heat dissipation and reduced fade during extended use. ICON’s internal Bump Zone increases damping by 20 percent near full compression to help reduce harsh bottoming and maintain suspension control during high-velocity compression. A one-piece digressive piston, application-specific valving, premium 5WT shock oil, and a 7/8-inch induction-hardened chrome-plated shaft support consistent performance across a wide range of temperatures and terrain.
Built with CNC-machined 6061 aircraft-grade aluminum components, hard-anodized aluminum cylinders, PTFE-lined spherical bearings, and application-specific mounting hardware, these shocks are engineered for durability and corrosion resistance. The ICON 57841EP set is fully rebuildable and re-tunable, allowing the suspension to be serviced and customized as your vehicle and driving needs evolve. Application note: Compatible with 3 to 3.5 inches of rear lift on non-TRD Tundras or 3 inches of rear lift on TRD Tundras equipped with rear coil springs.
