ICON 2007-2021 Toyota Tundra Rear 2.5 Series Shocks VS IR - Pair| 57620P

Product Description

If you drive a 2007‑2021 Toyota Tundra and you’re ready to upgrade the rear suspension from stock to serious performance level — the ICON Vehicle Dynamics 2.5 VS IR Rear Shock Pair (Part No. 57620P) is engineered to deliver. Specifically tuned for the Tundra’s rear geometry and ride demands (0‑1.5″ lift range), this pair of shocks brings high‑end materials, substantial internal improvements and performance benefits whether on highway, hauling, or off‑road. 

Technical Highlights & Benefits

• Large 2.5″ diameter aluminum body with internal reservoir (IR) monotube design which improves oil volume and heat dissipation compared to smaller shocks. 

• Vehicle‑specific valving (“V.S.” series) — these shocks are configured for the Tundra rear suspension in both length and damping tune. 

• Nitrogen‑charged monotube design: enhances performance under repeated cycles, maintains damping consistency under load or heat.

• Premium build quality: 6061 CNC machined aluminum components, 7/8″ induction‑hardened chrome‑plated shock shafts, PTFE‑lined spherical bearings, polyurethane bushings, forged steel mounts. 

• 100% rebuildable and re‑valveable: meaning you’re investing in a high‑quality component with serviceability rather than a throw‑away replacement. 

• Optimized for up to approximately 0‑1.5″ of rear lift on 2007‑2021 Tundra models (when using coil‑spring rear setup). 

Why You Should Buy It

• Better ride quality: Upgrading the rear shocks to the 2.5 VS IR design means your Tundra will feel more composed — less harshness over bumps, improved compliance and smoother transitions under both light and heavy load.

• Enhanced control under load/tow/off‑road: With larger bore shocks, internal reservoir design and vehicle‑specific valving, you get greater axle control, less unwanted rear‑end movement, more consistent behavior when hauling or off‑road.

• Durability and long‑term value: The materials, serviceability, rebuildable design all signal this is a performance investment—not just a height or “look” upgrade.

• Tailored fit for your truck: Because this part is built for the 2007‑21 Tundra rear suspension (in the specified lift range), you skip the guesswork and compromises of generic shock solutions.

• Support for lifted or upgraded builds: If you’ve moderately lifted your Tundra’s rear (up to ~1.5″) or plan to use larger tires, upgraded load or off‑road use, these shocks align with those demands rather than leaving the stock shocks behind.

Ideal For You If…

• You own a 2007‑2021 Toyota Tundra and are looking to upgrade the rear suspension for better performance—whether for towing, hauling, off‑road, or better general ride.

• You have (or plan) a modest rear lift (~0‑1.5″), or simply want significantly better shock performance while retaining near‑stock height.

• You use your truck for more than commuting (e.g., load haul, gear, off‑road) and want rear suspension that keeps up.

• You value engineering, materials, tune specificity (rather than basic “lift shocks”), and plan for long‑term durability.

Installation & Considerations

• The kit is sold as a pair (one left + one right). Confirm you have both sides for full replacement. 

• Ensure fitment with your exact year and rear suspension configuration; this part is for 2007‑21 Tundra rear shocks. Wrong fitment may result in sub‑optimal behavior or clearance issues. 

• Because of the upgraded internal design, ensure other rear suspension components (springs, bushings, mounts) are in good condition to maximize the benefit. Worn springs or mounts will reduce performance gain.

• After installation, check ride height, rear axle droop/travel, clearance (especially if you have larger tires or off‑road use). A full alignment and inspection is prudent.

• Since these shocks are rebuildable / re‑valveable, maintaining proper service intervals may prolong performance, especially if you push the truck hard.

• Although the part is tuned for ~0‑1.5″ lift, if your rear lift is significantly more (or less) than that, check with ICON or your installer whether the tune is still appropriate.

In summary: The ICON 57620P Rear 2.5 VS IR Shock Pair is a technically advanced performance upgrade for your 2007‑21 Toyota Tundra—delivering better ride, control and durability, especially for loads, off‑road or performance use.
