ICON 57840EP 2022-2023 Toyota Tundra 2.5 Aluminum Series Rear Shocks with Remote Reservoir and CDEV, Pair

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 #23: Compatible with 0-4” of rear lift on Sequoias without TRD Off Road package or 0-2" of rear lift on Sequoias equipped with TRD Off Road package and Sequoia TRD Pro.

• 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
• 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
• 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
• PTFE lined spherical bearings and application specific mounting hardware
• 7/8” diameter induction hardened, chrome plated shock shaft
• Nitrogen charged monotube design with remote reservoir
• 6061 aircraft grade aluminum CNC machined components
• Fully rebuildable and re-tunable

Upgrade the rear suspension of your 2022-2023 Toyota Tundra with the ICON 57840EP Vehicle Specific 2.5 Aluminum Series shocks. Designed and tuned specifically for the Tundra, this pair of rear shocks delivers controlled off-road performance while maintaining a smooth, comfortable ride on the street. Vehicle-specific valving and shock lengths help optimize suspension response for the intended application, while the remote reservoir design improves heat dissipation and helps reduce shock fade during extended, demanding use.
The included ICON Compression Damping Electronic Valve (CDEV) provides convenient in-vehicle compression damping adjustment. Powered by ICON Intelligent Control and the ICON mobile app, the system uses onboard G-force and gyroscope data along with user-defined settings to help adjust shock behavior for changing terrain. The valve can make precise damping changes in less than 40 milliseconds, offering a broad range of control without requiring manual adjustments at the shock.
Each shock features a one-piece digressive piston, premium 5WT shock oil, a nitrogen-charged monotube design, and a 7/8-inch induction-hardened, chrome-plated shaft. ICON’s internal Bump Zone can add 20% damping force near full compression to help control the suspension and reduce harsh bottoming. Hard-anodized aluminum cylinders, 6061 aircraft-grade aluminum components, PTFE-lined spherical bearings, and application-specific mounting hardware provide durability for demanding use. The shocks are fully rebuildable and re-tunable for long-term serviceability. This application is compatible with 0 to 4 inches of rear lift on Sequoias without the TRD Off Road package or 0 to 2 inches on Sequoias equipped with the TRD Off Road package and Sequoia TRD Pro. Confirm vehicle configuration and lift requirements before installation.
