Drastically improves vehicle damping ability off-road
Increased vehicle stability on-road
Utilizes factory lower control arms
Maintains OE track width
Vehicle-specific tuned secondary shocks provide increased damping and oil volume
CDC Valve technology allows for quick and easy compression damping adjustment
2.5 Aluminum Series secondary shocks feature one-piece impact extruded aluminum cylinders for excellent corrosion resistance and consistent finish
Shocks are fully rebuildable and revalveable
Mostly bolt-on design makes for straightforward install 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. The addition of secondary 2.5 Aluminum Series remote reservoir shocks means rougher terrain and larger off-road obstacles can be overcome with confidence as the damping ability of the vehicle’s suspension is effectively doubled. The included ICON CDC Valve is an externally adjustable valve that restricts oil flow into the reservoir which creates 10 levels of compression damping force ranges. As opposed to overly complicated and expensive long travel kits, the ICON S2 System is an affo rdable upgrade that drastically increases off-road performance, is easy to install, and has a modular design that allows 4Runner/FJ Cruiser owners to upgrade in steps or all at once.
