ICON 57840XP 2.5 Series Rear Shocks with CDXS Remote Reservoirs for 2022+ Toyota Tundra and 2023 Toyota Sequoia

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. ICON's exclusive Compression Damping Dual Speed (CDXS) valves are included for precisely dialing in your suspension performance. CDXS controls fluid flow under compression, with independent adjustability of high speed and low speed compression force. 10 discreet detented settings for both low and high-speed adjustment knobs allow separate adjustments for handling response and overall aggressiveness. 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.

• 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 your suspension performance with the ICON 57840XP Vehicle Specific 2.5 Aluminum Series rear shocks. Designed for select 2022 Toyota Tundra applications and 2023 Toyota Sequoia models, these shocks are engineered with vehicle-specific lengths and damping tunes to deliver controlled off-road performance without sacrificing street comfort. The pair includes remote reservoir shocks suited for rear lift applications, helping maintain consistent damping during demanding driving conditions.
The ICON 57840XP shocks feature Compression Damping Dual Speed (CDXS) adjusters with 10 detented settings for both high-speed and low-speed compression. Independent adjustment lets you fine-tune handling response, suspension aggressiveness, and overall ride behavior. A one-piece digressive piston with application-specific valving provides responsive control, while the remote reservoir improves heat dissipation to help reduce shock fade during prolonged off-road use. ICON’s internal Bump Zone adds damping force as the shock approaches full compression, helping control the suspension and reduce harsh bottom-out events.
Built for long-term serviceability, each shock uses a nitrogen-charged monotube design, premium 5WT shock oil, a 7/8-inch induction-hardened chrome-plated shaft, and a hard-anodized aluminum cylinder for corrosion resistance and a consistent finish. PTFE-lined spherical bearings, application-specific mounting hardware, and CNC-machined 6061 aircraft-grade aluminum components support dependable installation and operation. The ICON 57840XP is fully rebuildable and re-tunable for continued performance. Application note: compatible with 0 to 4 inches of rear lift on Sequoia models without the TRD Off Road package, or 0 to 2 inches of rear lift on Sequoia models equipped with the TRD Off Road package or TRD Pro.
