ICON V.S. 2.5 Aluminum Rear Shocks Remote Reservoir CDXS for 2022-2026 Toyota Tundra

The ICON V.S. 2.5 Aluminum Series rear shock absorbers are a vehicle-specific pair engineered for 2022–2026 Toyota Tundra builds running 3–3.5" of rear lift (3" on TRD Tundras with rear coil springs). Each shock features a remote reservoir, a 6061-billet aluminum Bump Zone manifold, and ICON's Compression Damping Dual Speed (CDXS) valve for independent high- and low-speed compression adjustment, giving Tundra owners precise, tunable control on the trail and a composed ride on the street.

Tunable Compression From Low-Speed Handling to High-Speed Hits

ICON's CDXS valve controls fluid flow under compression with two separate adjustment knobs: one for low-speed compression (handling response and body control) and one for high-speed compression (aggressiveness over sharp impacts). Each knob has 10 discrete detented positions, so changes are repeatable and deliberate rather than approximate. For a Tundra that sees both highway miles and rough two-track, this means one shock can be dialed for a comfortable daily setting and quickly adjusted for a more aggressive off-road tune without swapping components.

Bump Zone Manifold Prevents Harsh Bottom-Outs

A 6061-billet aluminum manifold positioned just below the top cap creates an internal Bump Zone that adds 20% more damping force as the shock approaches full compression. On a heavy truck like the Tundra, that progressive resistance absorbs the energy of high-velocity compression events (square-edged whoops, sudden drop-offs) before the suspension runs out of travel, reducing the jarring bottom-outs that wear on the truck and the driver over a long day off-road.

Remote Reservoir and Aluminum Construction for Sustained Performance

The remote reservoir increases fluid volume, which dissipates heat more effectively during prolonged hard use and reduces shock fade on extended off-road runs. The one-piece, hard-anodized, impact-extruded aluminum cylinder resists corrosion and maintains a consistent finish over time. The 7/8" induction-hardened, chrome-plated shock shaft and PTFE-lined spherical bearings are built to handle the side loads and debris exposure that come with lifted truck use. Both shocks are fully rebuildable and re-tunable, so the investment extends well beyond the first service interval.

Features

• CDXS Valve: independent 10-position high-speed and low-speed compression adjustment
• Bump Zone Manifold: 6061-billet aluminum manifold adds 20% damping force near full compression
• Remote Reservoir: increases fluid volume for improved heat dissipation and reduced fade
• Nitrogen-Charged Monotube: one-piece digressive piston with vehicle-specific valving
• 7/8" Shock Shaft: induction-hardened, chrome-plated for durability under load
• Fully Rebuildable: serviceable and re-tunable for long-term use

Specifications

Who This Is For and Isn't

These shocks suit 2022–2026 Toyota Tundra owners running 3–3.5" of rear lift (or exactly 3" on TRD Tundras with rear coil springs) who want tunable, high-performance damping for mixed on-road and off-road use and expect to service or re-tune their suspension over time.

These shocks are not compatible with Tundras equipped with Load-Leveling Rear Height Control Air Suspension or Adaptive Variable Suspension (AVS). They are not a universal fit and are not designed for lift heights outside the 3–3.5" range stated above.

Common Questions

Will these shocks fit a Tundra with the factory air suspension or AVS?

No. The ICON V.S. 2.5 Aluminum Series rear shocks (SKU 57841XP) are not compatible with 2022–2026 Toyota Tundras equipped with Load-Leveling Rear Height Control Air Suspension or Adaptive Variable Suspension (AVS). Buyers with either of those factory systems should confirm an alternative application before ordering.

What lift height do these shocks require?

These ICON rear shocks are configured for 3–3.5" of rear lift on non-TRD 2022–2026 Toyota Tundras, or exactly 3" of rear lift on TRD Tundras equipped with rear coil springs. Using them outside the stated lift range is not supported by ICON's application data.

How does the CDXS valve work and why does it matter?

The CDXS (Compression Damping Dual Speed) valve on these ICON rear shocks provides two separate adjustment knobs: one for low-speed compression (body roll and handling response) and one for high-speed compression (reaction to sharp impacts). Each knob has 10 discrete detented positions, allowing repeatable, independent tuning for different terrain or load conditions without removing the shock.

What is the Bump Zone and what does it do?

The Bump Zone is created by a 6061-billet aluminum manifold positioned just below the top cap of each shock. As the shock approaches full compression, this manifold increases damping force by 20%, providing progressive resistance that helps prevent harsh bottom-outs during high-velocity compression events. This is a meaningful benefit on a heavy truck like the Tundra running rough terrain.

Are these shocks rebuildable?

Yes. The ICON V.S. 2.5 Aluminum Series rear shocks are fully rebuildable and re-tunable. ICON provides an installation guide, and the shocks are designed to be serviced rather than replaced as a unit, extending the usable life of the product beyond the initial installation.

Is there a California Proposition 65 warning for this product?

Yes. This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm. This warning applies to the ICON V.S. 2.5 Aluminum Series rear shocks (SKU 57841XP) as sold.
