ICON 57872EP 2.5 Aluminum Remote Reservoir Rear Shocks with CDEV for 2025-2026 Toyota 4Runner, 0-3-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. 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. 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. ICON 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. They feature remote reservoirs and are 100% rebuildable/revalveable. APPLICATION NOTE #55: Shocks are fully serviceable. Lift heights indicated are for a stock equipped vehicle.

Upgrade the suspension performance of your 2025-2026 Toyota 4Runner with ICON Part Number 57872EP 2.5 Aluminum Series rear shock absorbers. Designed specifically for applications with 0-3 inches of lift, these shocks combine vehicle-specific length and damping with remote reservoir technology for improved control off-road and a smoother ride on pavement. The nitrogen-charged monotube design, one-piece digressive piston, and premium 5WT shock oil deliver consistent damping across a broad range of temperatures and driving conditions.
Included CDE Valve technology provides electronically adjustable compression damping from inside the vehicle through ICON Intelligent Control and the proprietary ICON mobile app. The system uses onboard G-force and gyroscope data along with user-defined settings to help adjust shock response for changing terrain. With reaction times of less than 40 milliseconds and application-specific hydraulic tuning, the system provides precise control for both everyday driving and demanding trail use.
ICON’s internal Bump Zone adds up to 20% more damping force as the shock approaches full compression, helping reduce harsh bottoming and improve suspension control during high-speed compression. Remote reservoirs increase heat dissipation to help minimize fade during prolonged use, while hard-anodized, impact-extruded aluminum cylinders provide corrosion resistance and a durable finish. PTFE-lined spherical bearings, application-specific mounting hardware, a 7/8-inch induction-hardened chrome-plated shaft, and a rubber dust boot support long-term performance.
The ICON 57872EP rear shock absorbers are fully rebuildable and re-tunable for serviceability and future suspension adjustments. CNC-machined 6061 aircraft-grade aluminum components provide strength with a refined fit and finish. This set is intended for compatible 2025-2026 Toyota 4Runner applications and includes the components needed for a performance-focused rear shock upgrade. Professional installation is recommended, and lift-height references apply to stock-equipped vehicles.
