ICON 57840CP 2.5 Series CDC Valve Remote Reservoir Rear Shocks for 2022+ Toyota Tundra, 0-1-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 CDC Valve is an externally adjustable valve that restricts oil flow into the reservoir which creates 10 levels of compression damping force ranges. 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 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.

• One-piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road

• 6061 aircraft grade aluminum CNC machined components
• Fully rebuildable and re-tunable

ICON Part Number 57840CP is a vehicle-specific rear shock set designed for the 2022 and newer Toyota Tundra. These 2.5 Aluminum Series shocks are engineered to deliver controlled off-road performance while maintaining a smooth, composed ride on the street. The application-specific length and damping calibration support Tundras with 0 to 1 inch of rear lift, providing suspension control suited to the vehicle and intended ride height. This set includes a pair of shocks with remote reservoirs and ICON CDC Valve technology for externally adjustable compression damping.
Each shock uses a one-piece digressive piston with vehicle-specific valving to improve ride quality and suspension response across changing terrain. ICON’s internal Bump Zone increases damping force by 20 percent as the shock approaches full compression, helping reduce harsh bottom-out events and improving control during high-velocity suspension compression. The remote reservoir helps dissipate heat during prolonged or demanding use, while premium 5WT shock oil supports consistent damping across a broad temperature range.
The hard-anodized, impact-extruded aluminum cylinders provide corrosion resistance and a durable finish. CNC-machined 6061 aircraft-grade aluminum components, PTFE-lined spherical bearings, application-specific mounting hardware, and a 7/8-inch induction-hardened chrome-plated shaft support long-term performance. The nitrogen-charged monotube design is fully rebuildable and re-tunable, allowing the shocks to be serviced or recalibrated as vehicle use and suspension requirements change. ICON CDC Valve adjustment provides 10 levels of compression damping control through a convenient external knob.
