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 Omega bypass 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 ICON Omega Bypass shocks feature two bypass tubes, creating multiple damping zones within the shocks, and externally adjustable bypass valves that restricts oil flow through the tubes to provide 28 settings of compression and rebound adjustment, with no tools required. As opposed to overly complicated and expensive long travel kits, the ICON S2 System is an affordable 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.
