ICON V.S. 2.5 Series Front Secondary Piggyback Shocks for 2007-2021 Toyota Tundra 6" Lift, Pair

The ICON V.S. 2.5 Series Front Secondary Piggyback Shocks are a sold-as-pair front shock upgrade for 2007–2021 Toyota Tundra builds running 6 inches of lift. Each shock is length- and valving-tuned specifically for this Tundra application, built around a nitrogen-charged monotube body with a piggyback reservoir, and is fully rebuildable and revalveable.

Vehicle-Specific Valving, Not a Generic Tune

ICON's V.S. (Vehicle Specific) designation means the damping tune and shock length are set for the 2007–2021 Tundra at 6 inches of lift, not adapted from a universal shock and shimmed to fit. The one-piece digressive piston works with that application-specific valving to deliver controlled compression and rebound across a wide range of speeds, whether the truck is loaded on a highway or unloaded on a rocky trail. Premium-grade 5WT shock oil maintains consistent damping across a broad temperature range, so performance does not degrade between a cold morning start and a long afternoon run.

Bump Zone: 20% More Damping Where It Counts

A 6061 billet aluminum manifold positioned a few inches below the top cap creates ICON's internal Bump Zone. As the shock approaches full compression, this zone increases damping force by 20%, reducing harsh bottom-outs and keeping the suspension composed during high-velocity compression events. The piggyback reservoir improves heat dissipation during sustained off-road use, helping resist shock fade on extended runs where a standard shock would begin to lose consistency.

Built to Last and Built to Be Serviced

The shock body is CAD-plated, precision-machined 1026 DOM steel. The shaft is 7/8-inch diameter, induction-hardened, and chrome-plated for corrosion and wear resistance. CNC-machined 6061 aircraft-grade aluminum components are used throughout. PTFE-lined spherical bearings and application-specific mounting hardware are included. Every V.S. 2.5 Series shock is 100% rebuildable and 100% revalveable, meaning the shock can be serviced and retuned rather than replaced when it eventually needs attention. These shocks can also be upgraded to ICON's Compression Damping Control Valve (CDCV) for a more user-adjustable tune.

Specifications

Who This Is For and Isn't

These shocks suit 2007–2021 Toyota Tundra owners running a 6-inch lift who want a front secondary shock with vehicle-specific damping tuning, piggyback reservoir heat management, and a body built for long-term serviceability on and off-road.

These shocks are not compatible with Tundra builds at lift heights other than 6 inches, and they are not a fit for any other make, model, or year. They are secondary shocks only and do not include coil springs, a complete coilover, or any other suspension component.

Common Questions

What years and lift height do these shocks fit?

These ICON V.S. 2.5 Series front secondary piggyback shocks are fitment-specific to 2007–2021 Toyota Tundra trucks running exactly 6 inches of lift. They are not designed for other lift heights or other vehicle applications.

Are these shocks sold as a pair or individually?

These ICON V.S. 2.5 Series front shocks are sold as a pair (SKU 59705P-CB), covering both front positions on the 2007–2021 Toyota Tundra.

What does the internal Bump Zone do?

The Bump Zone is created by a 6061 billet aluminum manifold positioned just below the shock's top cap. As the shock nears full compression, it increases damping force by 20%, which helps prevent harsh bottom-outs and keeps the suspension controlled during high-speed compression events.

Can these shocks be rebuilt or retuned?

Yes. Every ICON V.S. 2.5 Series shock is 100% rebuildable and 100% revalveable. They are also compatible with ICON's Compression Damping Control Valve (CDCV) upgrade for owners who want a more user-adjustable compression tune.

Does this listing include a California Proposition 65 warning?

Yes. These ICON V.S. 2.5 Series shocks carry a California Proposition 65 warning: this product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm.
