ICON V.S. 2.5 Aluminum Rear Shock Absorbers for 2022-2026 Toyota Tundra

The ICON Vehicle Dynamics V.S. 2.5 Aluminum Series rear shock absorbers (SKU 57841CP) are a vehicle-specific, nitrogen-charged monotube pair engineered for 2022–2026 Toyota Tundra builds running 3–3.5 inches of rear lift on non-TRD models, or 3 inches of rear lift on TRD models equipped with rear coil springs. Each shock ships with a remote reservoir and ICON's externally adjustable CDC Valve, and the pair is sold ready to install.

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.

Tunable Compression Damping on the Trail

The ICON CDC (Compression Damping Control) Valve is an externally adjustable knob that restricts oil flow into the remote reservoir across 10 distinct levels. A driver can dial in a softer setting for highway miles and step up to a firmer tune before dropping into a wash or running a high-speed dirt road, without removing the shock or cracking a bleed screw. The remote reservoir itself improves heat dissipation during sustained off-road use, reducing the shock fade that builds when a conventional shock body absorbs all the thermal load alone.

Internal Bump Zone for High-Speed Control

A 6061 billet aluminum manifold positioned a few inches below the top cap creates what ICON calls an internal Bump Zone. As the shock approaches full compression at high velocity, this zone adds approximately 20% of additional damping force, resisting harsh bottom-outs without stiffening the mid-stroke ride. For a Tundra running loaded with a bed full of gear or a camper, that progressive resistance at the end of travel is the difference between a controlled compression and a jarring impact that unsettles the truck.

Aircraft-Grade Construction, Fully Rebuildable

The shock cylinder is one-piece, hard-anodized, impact-extruded aluminum, which resists corrosion and holds a consistent finish through seasons of mud, salt, and UV exposure. The 7/8-inch shock shaft is induction-hardened and chrome-plated. Internal components are CNC-machined from 6061 aircraft-grade aluminum. PTFE-lined spherical bearings and application-specific mounting hardware are included. Premium 5WT shock oil maintains consistent damping across a wide temperature range. Because the shocks are fully rebuildable and re-tunable, the valving and seals can be serviced rather than replaced when the time comes.

Features

• 10-Level CDC Valve: externally adjustable compression damping with a single knob, no tools required
• Internal Bump Zone: 6061 billet aluminum manifold adds 20% damping force near full compression to resist bottom-outs
• Remote Reservoir: separates heat from the shock body to reduce fade during prolonged off-road use
• Hard-Anodized Aluminum Cylinder: one-piece, impact-extruded construction for corrosion resistance and consistent finish
• 7/8" Chrome-Plated Shaft: induction-hardened for durability; PTFE-lined spherical bearings included
• Fully Rebuildable and Re-Tunable: valving and seals are serviceable; vehicle-specific length and damping tune from the factory

Specifications

Who This Is For and Isn't

These shocks suit 2022–2026 Toyota Tundra owners who have installed or are planning 3–3.5 inches of rear lift (non-TRD) or exactly 3 inches of rear lift (TRD models with rear coil springs), and who want externally adjustable, rebuildable rear damping for mixed on-road and off-road use.

These shocks are not compatible with Tundra models equipped with Load-Leveling Rear Height Control Air Suspension or with Adaptive Variable Suspension (AVS). They are not a fit for lift heights outside the stated ranges, and they do not replace front shocks or any other suspension component. California residents: this product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm (Proposition 65).

Common Questions

Do these shocks work with the factory Tundra air suspension?

No. The ICON V.S. 2.5 Aluminum rear shocks (57841CP) are not compatible with Tundra models equipped with Load-Leveling Rear Height Control Air Suspension or Adaptive Variable Suspension (AVS). Buyers with either of those factory systems should not use this product.

What lift height is required for these shocks to fit correctly?

These rear shocks are sized for 3–3.5 inches of rear lift on non-TRD 2022–2026 Tundras, or 3 inches of rear lift on TRD Tundras equipped with rear coil springs. Lift heights outside those ranges are not supported by this application.

How does the CDC Valve adjustment work?

The ICON CDC Valve is an externally accessible knob on the remote reservoir that restricts oil flow between the shock body and the reservoir. Turning it steps through 10 levels of compression damping force, from softer street-oriented settings to firmer off-road tuning, without removing the shock from the vehicle.

Can these shocks be rebuilt or revalved later?

Yes. The ICON V.S. 2.5 Aluminum Series shocks are fully rebuildable and re-tunable. Seals and valving can be serviced by a qualified shop, extending the usable life of the shock rather than requiring full replacement.

What is included with the purchase?

The listing includes a pair of two rear shock absorbers with remote reservoirs and CDC Valves, PTFE-lined spherical bearings, and application-specific mounting hardware. An optional reservoir hose shield kit is available separately.
