ICON V.S. 2.5 Rear Shocks for 2007-2021 Toyota Tundra 6-Inch Lift Pair

The ICON Vehicle Dynamics V.S. 2.5 Aluminum Series Rear Shocks (SKU 57621P, sold as a pair) are nitrogen-charged monotube shocks built specifically for 2007–2021 Toyota Tundra trucks running a 6-inch rear lift. Length and damping are tuned for this exact application, not adapted from a universal shock.

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.

Application-Specific Tuning That Shows on the Trail

ICON configures the V.S. 2.5's valving and body length for each vehicle application individually. For Tundra owners, that means the shock arrives calibrated for the suspension geometry and load characteristics of a 6-inch lifted truck, not a compromise setting shared across platforms. The one-piece digressive piston design translates that tuning into consistent damping whether the road is smooth pavement or broken two-track.

More Oil Volume, Better Heat Management

The 2.5-inch aluminum body carries more oil than the V.S. 2.0 Series, which directly improves heat dissipation during sustained off-road use. Heat buildup is a primary cause of fade in smaller-diameter shocks; the larger oil volume of the V.S. 2.5 keeps damping consistent across longer runs. Premium 5WT shock oil maintains that consistency across a wide temperature range, from cold desert mornings to sustained high-speed desert running.

Built to Be Serviced, Not Replaced

Both shocks in the pair are 100% rebuildable and 100% revalveable. One-piece impact-extruded 6061 aircraft-grade aluminum cylinders resist corrosion and hold tight tolerances over time. PTFE-lined spherical bearings, polyurethane bushings, and forged steel mounting stems handle the articulation and load cycles of off-road driving without the slop that develops in OE rubber bushings. The 7/8-inch induction-hardened, chrome-plated shock shafts resist bending and surface wear.

Specifications

Who This Is For and Isn't

These shocks suit 2007–2021 Toyota Tundra owners who have installed or are building a 6-inch rear lift and want application-tuned damping with a rebuildable, serviceable shock body rated for both street and off-road use.

These shocks cover the rear position only and are not a complete suspension system. Front shocks, springs, and other lift components are sold separately. They are not compatible with Tundra model years outside 2007–2021, with lift heights other than 6 inches, or with other Toyota models. California residents should note the Proposition 65 warning: this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.

Common Questions

What vehicles and lift height do these shocks fit?

These ICON V.S. 2.5 rear shocks are built specifically for 2007–2021 Toyota Tundra trucks with a 6-inch rear lift. The body length and damping tune are set for that exact application; they are not compatible with other lift heights or other vehicle models.

Are front shocks included?

No. This listing covers the rear shock pair only (SKU 57621P). Front shocks, coilovers, springs, and any other lift components needed to complete a 6-inch system are sold separately.

Can these shocks be rebuilt or revalved after heavy use?

Yes. The ICON V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable, meaning the internals can be serviced or the damping tune adjusted without replacing the entire shock body.

How do the V.S. 2.5 shocks compare to ICON's V.S. 2.0 Series?

The V.S. 2.5 Aluminum Series uses a larger 2.5-inch body diameter, which increases oil volume compared to the V.S. 2.0 Series. More oil volume improves heat dissipation during sustained off-road use and helps maintain consistent damping as the shocks cycle repeatedly.
