ICON S2 Secondary Shock System Stage 1 for 2007-2021 Toyota Tundra

ICON Stage 1 S2 Secondary Shock Upgrade System (2007–2021 Toyota Tundra 0-3 inches Lift)

Part Number: K53151

Summary: The ICON Vehicle Dynamics Stage 1 S2 Secondary Shock System redefines the off-road capability of the 2007–2021 Toyota Tundra by allowing for the installation of a secondary shock to an existing ICON coilover setup. This system effectively doubles the damping ability of the vehicle’s front suspension by adding a 2.5 Series piggyback reservoir secondary shock. Designed to enhance performance over rougher terrain and larger off-road obstacles, this S2 upgrade provides professional-grade bypass-style damping without the need for custom fabrication.

Features

• S2 Secondary Damping: Vehicle-specific tuned 2.5 Series piggyback shocks provide increased oil volume and damping force to ensure superior control during high-speed off-road use.
• Performance Geometry: Utilization of factory lower control arms and maintenance of OE track width provides increased vehicle stability on-road to ensure predictable handling characteristics.
• System Durability: Fully rebuildable and revalveable shock components provide a long-term suspension solution to ensure consistent performance over the life of the vehicle.
• Installation: Simple and straightforward bolt-on hoop design (with required welding to the lower control arm) provides a secure mounting point to ensure maximum structural integrity.
