ICON Stage 1 S2 Secondary Shock Upgrade System 0-3.5 inches Lift for 2010–2024 Toyota 4Runner & 2010–2014 Toyota FJ Cruiser

Part Number: K53121

Summary: The ICON S2 Secondary Shock System redefines off-road capability for the 2010–2024 Toyota 4Runner and 2010–2014 Toyota FJ Cruiser by allowing the installation of a secondary shock to an existing ICON coilover setup. This Stage 1 system provides a 0-3.5 inches front lift range and effectively doubles the vehicle’s damping ability to tackle rougher terrain and larger obstacles with confidence. The S2 system utilizes a modular design that maintains the factory track width and works with OE lower control arms, offering a high-performance alternative to expensive long-travel kits.

Features

• S2 Secondary Damping: Vehicle-specific tuned secondary 2.5 Aluminum Series remote reservoir shocks provide increased damping and oil volume to ensure superior control during aggressive off-road use.
• Aluminum Series Construction: One-piece impact extruded aluminum cylinders provide excellent corrosion resistance to ensure a consistent finish and long-term durability.
• Serviceable Design: Fully rebuildable and revalveable internals provide a customizable ride to ensure the longevity of your suspension investment.
• System Integration: A mostly bolt-on design utilizing factory lower control arms provides a straightforward installation to ensure a cost-effective performance upgrade.
