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

By adding secondary 2.5-inch Aluminum Series remote reservoir Omega bypass shocks, this system effectively doubles the vehicle’s damping capability for improved control over rough terrain, large obstacles, and demanding off-road conditions. It provides a substantial performance upgrade without requiring a complicated long-travel suspension kit.\u003cbr\u003eThe Omega bypass shocks use a two-tube bypass design with multiple internal damping zones and externally adjustable bypass valves. Drivers can make tool-free compression and rebound adjustments across 28 settings to fine-tune suspension response for changing terrain and driving conditions. Vehicle-specific tuning increases damping control and oil volume, while the remote reservoirs help support consistent performance during extended off-road use. The shocks are fully rebuildable and revalveable for long-term serviceability and customization.\u003cbr\u003eThe ICON S2 system features a mostly bolt-on installation and uses the factory lower control arms while maintaining original-equipment track width. Its modular design allows 4Runner and FJ Cruiser owners to install the upgrade in stages or complete the system at once. In addition to improved off-road damping and stability, the system enhances on-road vehicle control. Application Note #35: Remote reservoir mounting brackets may interfere with aftermarket bumper mounts or windshield washer bottles. Professional installation is recommended, and vehicle compatibility should be verified before ordering.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003e2.5-inch 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\u003eOmega Series two-tube bypass design provides adjustable compression and rebound damping\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eExternally adjustable bypass valves offer 28 tool-free damping settings\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVehicle-specific tuning delivers increased damping control and oil volume\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 capability for improved off-road control\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFully rebuildable and revalveable shocks support long-term service\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eImproves vehicle stability during on-road and off-road driving\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eUses factory lower control arms\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMaintains original-equipment track width\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":50543711813872,"sku":"K53123","price":3020.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/6242\/3792\/files\/a903b70843418ee24a80b7e7f6accd61.jpg?v=1790464565","url":"https:\/\/overlandgear.co\/products\/icon-s2-stage-3-secondary-shock-system-k53123-for-2010-2024-toyota-4runner-and-2010-2014-fj-cruiser","provider":"Overland Gear Co","version":"1.0","type":"link"}
