ICON V.S. 3.0 Series Rear Shock Absorbers with CDXS for 2022-2026 Toyota Tundra and 2023-2026 Sequoia

The ICON V.S. 3.0 Series Rear Shock Absorbers with Remote Reservoir and CDXS are a bolt-on OEM replacement pair engineered for the 2022–2026 Toyota Tundra and 2023–2026 Toyota Sequoia, delivering up to 20% more rear wheel travel than stock and a 3.0-inch body diameter that provides 50% greater piston surface area than ICON's 2.5 Series shocks. Lift compatibility and trim restrictions vary by vehicle configuration; see the application notes in the Specifications section before purchasing.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

More Travel, Less Fade

The 3.0-inch body diameter increases internal oil volume and external surface area relative to smaller-body shocks. That additional thermal mass resists shock fade during sustained hard use (repeated high-speed whoops, loaded towing on rough roads, or back-to-back trail runs), so damping performance stays consistent rather than degrading as heat builds. The 20% gain in rear wheel travel over stock means the suspension can absorb larger obstacles without topping or bottoming out, keeping the rear tires in contact with the ground longer and reducing the jarring that transfers into the cab.

Independent High- and Low-Speed Compression Tuning

The Compression Damping Dual Speed (CDXS) valve controls fluid flow under compression with two separate adjustment knobs: one for low-speed compression (body roll, brake dive, load response) and one for high-speed compression (sharp impacts, square-edged hits). Each knob has 10 detented positions, so changes are repeatable and easy to reverse. That separation matters because a single-knob shock forces a compromise: softening for comfort also softens for body control. CDXS lets a driver tune handling response and overall aggressiveness independently. When matched with ICON 3.0 Series front coilovers equipped with CDXS, the front-to-rear damping balance can be dialed in as a system.

Hardware Built for Longevity

Shock shafts are 7/8-inch diameter, induction hardened, and chrome plated for resistance to bending and surface wear. Shock bodies are CAD-plated steel for corrosion resistance. Spherical bearings are PTFE lined to minimize deflection and extend service life without requiring lubrication. CNC-machined 6061 aluminum components carry a black anodized finish. The shocks are fully rebuildable and re-tunable, so worn seals or a change in driving style does not require replacing the entire unit.

Features

• 3.0-inch body diameter: 50% more piston surface area than ICON 2.5 Series shocks for increased stability and heat dissipation
• CDXS valve: 10-position independent adjustment of high-speed and low-speed compression damping
• 20% more rear wheel travel: increased suspension travel compared to stock
• 7/8-inch hardened chrome shafts: induction hardened and chrome plated for durability
• PTFE-lined spherical bearings: extended longevity and minimal deflection
• Fully rebuildable and re-tunable: serviceable without full replacement

Specifications

Who This Is For and Isn't

These shocks suit 2022–2026 Toyota Tundra and 2023–2026 Toyota Sequoia owners running stock height or a moderate rear lift who want meaningfully more wheel travel, tunable compression damping, and hardware built to be rebuilt rather than replaced. They are particularly well matched to drivers who already run or plan to run ICON 3.0 Series front coilovers with CDXS, since the two systems can be tuned together front to rear.

These shocks do not fit any vehicle equipped with Toyota's Adaptive Variable Suspension (AVS). Lift compatibility is trim-specific: TRD Tundra models with rear coil springs are limited to 0–1 inch of rear lift, and Sequoia TRD Off Road and TRD Pro models are limited to 0–2 inches. Exceeding those limits is outside the stated fitment. These shocks are not compatible with vehicles outside the 2022–2026 Tundra and 2023–2026 Sequoia application.

Common Questions

What lift heights are these shocks compatible with on the Tundra?

The ICON 3.0 Series rear shocks (SKU 57845XP) are compatible with 0–1.5 inches of rear lift on non-TRD Tundra models, 0–1 inch on TRD Tundra models equipped with rear coil springs, and 0–3.5 inches on Tundra models equipped with OE load-leveling rear height control air suspension. Confirm your trim and suspension configuration before ordering.

Are these shocks compatible with Toyota's Adaptive Variable Suspension?

No. The ICON V.S. 3.0 Series rear shocks (SKU 57845XP) are not compatible with vehicles equipped with Toyota's Adaptive Variable Suspension (AVS). Check your build sheet or window sticker to confirm whether your Tundra or Sequoia includes AVS before purchasing.

What does the CDXS adjustment actually control?

The CDXS valve on these ICON 3.0 Series rear shocks provides two separate adjustment knobs: one for low-speed compression damping (which governs body roll, brake dive, and load response) and one for high-speed compression damping (which governs sharp impacts and square-edged hits). Each knob has 10 detented positions, allowing repeatable, independent tuning of handling response and overall aggressiveness.

How do these compare to ICON's 2.5 Series shocks?

The ICON 3.0 Series rear shocks have a 3.0-inch body diameter versus the smaller 2.5 Series body, resulting in 50% more piston surface area. That larger piston and greater internal oil volume improve damping consistency and heat dissipation under sustained hard use. The 3.0 Series also adds the CDXS dual-speed compression adjustment, which is not present on standard 2.5 Series shocks.

Is installation a bolt-on process?

The ICON 3.0 Series rear shocks are designed as a direct OEM shock replacement for the 2022–2026 Toyota Tundra and 2023–2026 Toyota Sequoia, and ICON describes installation as a bolt-on process. An installation guide is available from ICON. TerrainVault does not perform installation.
