🧾 Overview
The ICON Vehicle Dynamics 2.5 VS Secondary Piggyback Shocks for 2007–2021 Toyota Tundra are engineered specifically for use with 6-inch lift systems. Designed as a secondary front shock solution, these vehicle-specific tuned dampers provide improved ride control, heat management, and high-speed compression stability for lifted applications.
ICON’s 2.5 Series monotube design features a large 2.5” shock body paired with a piggyback reservoir to increase oil capacity and reduce fade during prolonged off-road use. An internal “Bump Zone” delivers approximately 20% additional damping force at the end of the compression stroke, helping prevent harsh bottom-outs during aggressive driving.
Each shock is application-specific in both length and valving, ensuring proper suspension balance for lifted Tundra setups. Like all ICON shocks, these are fully rebuildable and revalveable, allowing future tuning adjustments as your build evolves.
