ICON V.S. 3.0 Series Rear Shocks Remote Reservoir with CDEV for 2022-2026 Toyota Tundra / 2023-2026 Sequoia, Pair

The ICON V.S. 3.0 Series Rear Shock Absorbers with Remote Reservoir and CDEV 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 suspension travel than stock and a 3.0" body diameter that provides 50% more piston surface area than ICON's 2.5 Series shocks. Lift compatibility and trim-level 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" shock body increases internal oil volume and external surface area compared to ICON's 2.5 Series, which means heat generated during hard off-road use dissipates faster and shock fade is reduced during sustained trail driving. The larger piston area translates to more consistent damping force across the full range of suspension travel, so the rear end stays composed whether the terrain is a washboard forest road or a high-speed desert run.

Active Damping via CDEV

ICON's Compression Damping Electronic Valve (CDEV) is an electronically controlled valve that meters oil flow to regulate compression damping force. The valve reacts in under 40 milliseconds and is infinitely variable, allowing extremely precise adjustments for changing terrain. Hydraulic circuits are custom-tuned per application to maximize resolution and dynamic range for the Tundra and Sequoia specifically.

The CDEV system is powered by ICON Intelligent Control (IIC) and the ICON mobile app, which uses an onboard G-force sensor and gyroscope to predict terrain and adjust shock settings automatically based on algorithms and user-defined preferences. Note: the IIC kit is sold separately, and an iOS device is required to run the ICON Intelligent Control app.

Construction Built to Be Rebuilt

Shock shafts are 7/8" diameter induction-hardened and chrome-plated. Structural components are CNC-machined 6061 aluminum with a black anodized finish. PTFE-lined spherical bearings reduce deflection and extend service life. Steel shock bodies carry a corrosion-resistant CAD plating. The shocks are fully rebuildable and re-tunable, which matters for buyers who plan to run them hard over multiple seasons rather than replace them outright.

Who This Is For and Isn't

These shocks suit 2022–2026 Toyota Tundra and 2023–2026 Toyota Sequoia owners who want meaningfully more rear suspension travel and electronically adjustable compression damping for off-road use, within the lift ranges and trim-level limits stated above.

These shocks are not compatible with any vehicle equipped with Adaptive Variable Suspension (AVS). The ICON Intelligent Control kit required to operate the CDEV system is sold separately, and an iOS device is required to run the ICON Intelligent Control app (Android is not supported). Lift height limits differ by Tundra trim and suspension type; confirm your specific configuration against the application notes before ordering.

Common Questions

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

The ICON 3.0 Series rear shocks (57845EP) support 0–1.5" of rear lift on non-TRD Tundra models with rear coil springs, 0–1" on TRD Tundra models with rear coil springs, and 0–3.5" on Tundra models equipped with the OE load-leveling rear height control air suspension. Confirm your trim and suspension type before ordering.

What lift heights are supported on the Sequoia?

On the 2023–2026 Toyota Sequoia without the TRD Off Road package, these ICON 3.0 Series rear shocks support up to 4" of rear lift. On Sequoia TRD Off Road and TRD Pro models, the compatible range is 0–2" of rear lift.

Is the ICON Intelligent Control kit included?

No. The ICON Intelligent Control (IIC) kit required to operate the CDEV system on these 3.0 Series rear shocks is sold separately. An iOS-operated device is also required to run the ICON Intelligent Control app; Android is not supported.

Are these shocks compatible with Adaptive Variable Suspension?

No. The ICON V.S. 3.0 Series rear shocks (57845EP) are not compatible with vehicles equipped with Adaptive Variable Suspension (AVS). Verify that your Tundra or Sequoia does not have AVS before purchasing.

Can these shocks be rebuilt or retuned after extended use?

Yes. The ICON 3.0 Series rear shocks are fully rebuildable and re-tunable, which allows them to be serviced and restored to spec rather than replaced outright after hard use.
