ICON S2 Secondary Shock System – Stage 3 for 2010-2024 Toyota 4Runner

ICON Stage 3 S2 Secondary Shock Upgrade System (2010–2024 Toyota 4Runner / 2010–2014 FJ Cruiser)

Part Number: K53123

Summary: The ICON Vehicle Dynamics S2 Secondary Shock System redefines the off-road capability of the 2010–2024 Toyota 4Runner and 2010–2014 Toyota FJ Cruiser by allowing for the installation of a secondary shock to an existing ICON coilover setup. This Stage 3 system features 2.5 Aluminum Series Omega Bypass remote reservoir shocks, effectively doubling the vehicle’s damping ability to conquer aggressive terrain. A key differentiator is the Omega Bypass technology, providing 28 settings of compression and rebound adjustment without the need for tools.

Features

• Omega Series Bypass: Two-tube bypass design provides 28 settings of external compression and rebound adjustment to ensure precise damping control for any terrain.
• Secondary Damping: Vehicle-specific tuned 2.5 Aluminum Series shocks provide increased oil volume to ensure consistent performance and fade resistance during high-speed off-road use.
• System Durability: One-piece impact extruded aluminum cylinders provide excellent corrosion resistance to ensure a long-lasting, consistent finish.
• Installation: Mostly bolt-on design with required welding for lower shock tabs provides a secure fitment to ensure maximum structural integrity.
• Chassis Integrity: Maintenance of OE track width and use of factory lower control arms provides a cost-effective performance increase to ensure straightforward integration with existing components.
