ICON 57840P 2.5 Aluminum Series Remote Reservoir Rear Shocks for 2022-2023 Toyota Tundra

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. If you are looking for a more user defined tune, consider ICON compression adjustable shock absorbers equipped with CDCV, CDXS, or CDEV. 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
• All ICON 2.5 Aluminum Series Remote Reservoir shocks can be upgraded with an ICON compression adjuster (CDCV, CDXS, or CDEV)
• 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 piggyback reservoir
• 6061 aircraft grade aluminum CNC machined components
• Fully rebuildable and re-tunable

Upgrade your 2022-2023 Toyota Tundra with the ICON 57840P Vehicle Specific 2.5 Aluminum Series rear shocks. Designed for outstanding off-road control and a smooth on-road ride, these shocks use application-specific lengths and damping valving to match the Tundra suspension platform. This pair is compatible with 0-1 inch of rear lift and is engineered for reliable performance in demanding driving conditions.
The remote reservoir design improves heat dissipation to help reduce shock fade during prolonged off-road use. ICON’s one-piece digressive piston and vehicle-specific valving provide consistent damping and ride quality, while the internal Bump Zone increases damping force by 20% as the shock approaches full compression. This added control helps manage high-velocity suspension compression and reduce harsh bottoming.
Built with hard-anodized, impact-extruded aluminum cylinders, 6061 aircraft-grade aluminum CNC-machined components, and a 7/8-inch induction-hardened, chrome-plated shaft, the ICON 57840P is designed for durability and corrosion resistance. Premium 5WT shock oil maintains consistent damping across a wide temperature range, while PTFE-lined spherical bearings and application-specific mounting hardware support precise installation. The nitrogen-charged monotube shocks are fully rebuildable and re-tunable, and can be upgraded with an ICON CDCV, CDXS, or CDEV compression adjuster for a more customized suspension tune.
