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 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.\nThe ICON S2 Secondary Shock System redefines off-road capability by allowing the installation secondary shocks to an ICON coilover setup.

By adding secondary ICON 2.5 Aluminum Series remote reservoir shocks, the system effectively doubles the suspension damping capacity, helping the vehicle handle rough terrain, larger obstacles, and demanding trail conditions with greater control and stability. The system maintains the factory lower control arms and original track width for a practical upgrade that does not require a full long-travel conversion.\u003cbr\u003eThe included ICON CDC Valve provides 10 levels of externally adjustable compression damping. This allows drivers to fine-tune suspension performance by controlling oil flow into the remote reservoir, making it easier to adapt the vehicle to changing terrain and driving conditions. The vehicle-specific shock tuning increases damping performance and oil volume while the one-piece impact-extruded aluminum shock cylinders provide corrosion resistance, durability, and a consistent finish. The shocks are also fully rebuildable and revalveable for long-term serviceability.\u003cbr\u003eThe ICON S2 system features a mostly bolt-on installation and a modular design, allowing the upgrade to be completed in stages or installed as a complete system. It improves off-road damping and on-road stability while retaining factory-style packaging and compatibility with the existing ICON coilover configuration. Before installation, review ICON Application Note #35, as remote reservoir mounting brackets may interfere with certain aftermarket bumper mounts or windshield washer bottles. Professional installation is recommended to ensure proper fitment and suspension setup.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003e2.5 Aluminum Series secondary shocks use one-piece impact-extruded aluminum cylinders for corrosion resistance and a consistent finish\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVehicle-specific shock tuning provides increased damping control and oil volume\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eICON CDC Valve offers 10 levels of externally adjustable compression damping\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMostly bolt-on design supports a straightforward installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEffectively doubles suspension damping capacity for improved off-road control\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFully rebuildable and revalveable shocks support long-term serviceability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eImproves vehicle stability during on-road driving\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eUtilizes factory lower control arms\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMaintains original equipment track width\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFits 2010-2024 Toyota 4Runner and 2010-2014 Toyota FJ Cruiser models with an ICON coilover setup\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\nCompatible With\u003cbr\u003e\n2010 Toyota 4Runner\u003cbr\u003e\n2010 Toyota FJ Cruiser\u003cbr\u003e\n2011 Toyota 4Runner\u003cbr\u003e\n2011 Toyota FJ Cruiser\u003cbr\u003e\n2012 Toyota 4Runner\u003cbr\u003e\n2012 Toyota FJ Cruiser\u003cbr\u003e\n2013 Toyota 4Runner\u003cbr\u003e\n2013 Toyota FJ Cruiser\u003cbr\u003e\n2014 Toyota 4Runner\u003cbr\u003e\n2014 Toyota FJ Cruiser\u003cbr\u003e\n2015 Toyota 4Runner\u003cbr\u003e\n2016 Toyota 4Runner\u003cbr\u003e\n2017 Toyota 4Runner\u003cbr\u003e\n2018 Toyota 4Runner\u003cbr\u003e\n2019 Toyota 4Runner\u003cbr\u003e\n2020 Toyota 4Runner\u003cbr\u003e\n2021 Toyota 4Runner\u003cbr\u003e\n2022 Toyota 4Runner\u003cbr\u003e\n2023 Toyota 4Runner\u003cbr\u003e\n2024 Toyota 4Runner","brand":"ICON","offers":[{"title":"Default Title","offer_id":50543713190128,"sku":"K53122","price":2595.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/6242\/3792\/files\/4267f807b96e7183055b68eb4683c4fc.jpg?v=1790464589","url":"https:\/\/overlandgear.co\/products\/icon-k53122-s2-stage-2-secondary-shock-system-for-2010-2024-toyota-4runner-and-2010-2014-fj-cruiser","provider":"Overland Gear Co","version":"1.0","type":"link"}
