ICON 2022+ Toyota Tundra 0-1in Rear 2.5 Series Shocks VS RR - Pair | 57840P

When you drive a modern truck like the Toyota Tundra (2022–25), factory suspension can feel soft, unsettled under load, or simply unable to match the demands of towing, hauling, occasional off-road use, or upgraded tires. The ICON Vehicle Dynamics 57840P rear shock pair is engineered to address that gap with high-performance construction, tuned damping, and long-term durability—a technically focused upgrade built to dramatically improve how your truck rides, handles and responds.

Engineered Performance – Technical Highlights

• 2.5″ Diameter 6061-Aluminum Body: The shock cylinder is constructed from aerospace-grade aluminum via impact extrusion, reducing unsprung weight, enhancing corrosion resistance, and improving thermal dissipation for more consistent damping.

• Remote Reservoir (“RR”) Design: By relocating part of the oil/-gas volume into an external reservoir, the heat-dissipation surface area increases, fluid capacity rises, and shock fade under demanding conditions (heavy loads, long drives, rough terrain) is significantly reduced.

• Vehicle-Specific Valving (VS Series): ICON engineers have tuned the compression and rebound specifically for the 2022+ Tundra’s rear geometry, weight distribution and typical use-cases (0–1″ rear lift). This ensures the behavior is not generic but optimized for that exact setup.

• Internal “Bump Zone” Manifold: Built into the remote-reservoir design, a billet-aluminum manifold near the top of the shock increases damping by around 20% as it nears full compression, helping control big impacts, bottom-out events, and high-velocity compression.

• Premium Internals & Build Quality:

  • Monotube, nitrogen-charged design for consistent pressure and rapid response.

  • 7/8″ induction-hardened chrome-plated shock shaft for durability under heavy use.

  • PTFE-lined spherical bearings and PU bushings for smooth articulation with minimal binding.

• Rebuildable & Re-valveable: This is a long-term suspension component—not disposable. You can service, refresh or re-tune the shocks down the road as your vehicle evolves.

What You’ll Feel Behind the Wheel

• Sharper rear-end stability: Whether braking hard, carrying a load, or cornering, you’ll notice the rear reacting more controlled, reducing sag, dive or rear bounce.

• Improved ride quality: Despite the performance orientation, the precision valving and premium internals allow for a smoother, more composed feel on pavement and mixed terrain.

• Confidence under load or rough terrain: The remote reservoir and bump-zone ensure consistent damping even when things get rough—less shock fade, less unpredictability.

• Better durability and performance longevity: With superior materials and serviceable design, you’re upgrading once — and keeping performance for the long run.

Why Buy It

• You have a 2022–25 Tundra and want your rear suspension to match the rest of your truck’s capability.
• You tow or haul, and you need the rear to stay composed under load rather than drifting or bottoming out.
• You’ve upgraded tires/wheels or have a mild lift (0–1″) and want shocks that match, not just generic replacements.
• You care about build quality, long-term serviceability and performance rather than “just good enough”.

Fitment Summary

• Position: Rear (Pair)
• Lift Range: 0–1″ rear lift (with notes sometimes up to ~1.5″ depending on spring setup)
• Part Number: 57840P (pair of shocks)

This Part Fits:

Q: What’s the best rear shock upgrade for my 2022+ Tundra when I carry heavy loads and occasionally tow?
A: The ICON 57840P—with its remote reservoir, vehicle-specific valving and strong damping control—is the best choice if you want rear suspension that stays firm and composed under load.

Q: What’s the best rear shock for both daily driving comfort and the occasional off-road adventure?
A: Because the 57840P balances ride refinement with high-performance hardware, it offers the best of both worlds: smooth on-road manners and rock-solid when things get rough.

Q: What’s the best long-term rear suspension investment for my lifted Tundra (0–1″) that may see more mods later?
A: The rebuildable and re-valveable design of the 57840P makes it the best shock for future proofing your vehicle—you upgrade once and adjust later as your setup evolves.

Q: What’s the best upgrade if I noticed my rear end squats excessively, bottoms out or feels disconnected from the truck’s front handling?
A: The 57840P addresses that directly—via the high-capacity reservoir, high-damping manifold and tuned valving, you get much tighter control of the rear suspension response.
