ICON Vehicle Dynamics 57840CP 2.5″ VS CDCV Remote-Reservoir Rear Shock Pair – for 2022-25 Toyota Tundra (0-1.5″ Rear Lift) | 57840CP

If you’re driving a modern Toyota Tundra (2022–25) and you want real performance from the rear suspension—whether for daily use, towing or rough terrain—the ICON Vehicle Dynamics 57840CP rear shocks are engineered for exactly that. This is a technical upgrade designed to deliver measurable improvements in ride control, handling, durability and versatility.

Engineered Performance – Technical Highlights

• 2.5″ Diameter 6061-Aluminium Body: The shock body is crafted from premium aerospace-grade aluminium, which reduces unsprung weight, improves corrosion resistance and increases heat dissipation—this leads to more consistent damping under demanding conditions.
• Remote Reservoir Design: By relocating part of the oil/gas volume into an external reservoir, you gain increased fluid capacity and surface area for cooling, reducing shock fade during heavy use, towing or off-road.
• CDCV (Compression Damping Control Valve) Adjustable-Dial: This model features a 10-position external dial that lets you fine-tune the compression feel from smooth to firm, adjusting based on load, terrain or ride preference.
• Vehicle-Specific Valving (VS Series): ICON has tuned the compression and rebound characteristics specifically for the 2022+ Tundra with up to approximately 1.5″ rear lift (or compatible with up to ~3″ when using load-leveling air setups) — ensuring the behaviour is optimized for your truck’s geometry and use-case.
• Internal “Bump Zone” Manifold: Within the shock’s design a billet aluminium manifold increases damping force (about +20%) as the shock approaches full compression—this helps control bottoming out and harsh impacts when the rear axle travels quickly.
• Premium Internals & Serviceability: Includes a 7/8″ induction hardened chrome-plated shaft, nitrogen-charged monotube architecture for consistent pressure, PTFE-lined spherical bearings, customised mounts and full rebuild / re-valve ability for long-term use.

What You’ll Feel Behind the Wheel

• Tighter rear-end control: Less sag, less bounce and less body motion when towing, hauling or driving aggressively.
• Adaptable ride quality: With the adjustable compression dial you can switch from comfort-focused to performance-oriented depending on load, terrain or preference.
• Improved heat- and fade-resistance: The remote reservoir and aluminium body keep performance steady even under extended use or rough terrain.
• Better articulation and impact absorption: The bump-zone and tuned valving mean the rear behaves confidently on uneven surfaces without feeling harsh or uncontrolled.
• Durable long-term behaviour: Built to be serviced and tuned, this isn’t a throw-away part—it’s a durable upgrade built for serious use.

Why Buy It

• You own a 2022-25 Tundra and want your rear suspension to match the capability of your truck.
• You carry loads, tow a trailer or drive mixed terrain and need improved rear stability and control.
• You’ve lifted the rear (0-1.5″ typical) or have a load-leveling air setup and want shocks built for your specific geometry.
• You value high-end construction, adjustability and service-friendly components—not just basic replacements.
