The kit is length-optimized for 4WD but will also fit 2WD 4Runner models; buyers seeking maximum wheel travel on a 2WD build should reference the 2WD-specific part numbers instead.\u003c\/p\u003e\n\u003cp class=\"product-shipping-note\"\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground.

For the 6th-generation 4Runner, the coilover's travel envelope is sized to the factory geometry so the suspension cycles through its full range without binding or bottoming, whether on pavement or on trail. The 2.5-inch shock body provides greater piston surface area than the stock unit, which translates to more consistent damping force across a wider range of speeds and terrain inputs.\u003c\/p\u003e\n\n\u003ch2\u003eInternal Reservoir and Rebuildable Construction\u003c\/h2\u003e\n\u003cp\u003eThe internal reservoir separates oil from nitrogen gas inside the shock body, reducing aeration and heat buildup during extended off-road use. CAD-plated shock bodies resist corrosion, 7\/8-inch diameter shafts handle side-load stress, and FK rod end bearings minimize deflection over time. The shocks are fully rebuildable and re-tunable, so a worn valving stack or seal kit can be serviced without replacing the entire unit. That serviceability is a meaningful long-term cost consideration on a suspension component in this class.\u003c\/p\u003e\n\n\u003ch2\u003eLift Adjustability and Wheel Clearance\u003c\/h2\u003e\n\u003cp\u003eThe coilover's threaded body allows lift height to be set anywhere in the 1.25–3-inch range, letting the builder dial in ride height for a specific tire size or load. OEM wheels and tires are compatible at the lower end of the lift range. For aftermarket fitment, 17x8.5 with 6.32-inch backspace or ICON Alloys 18x9 with 6.6-inch backspace are recommended. Tires up to 33x11.50 fit without modification; larger tires may require fender trimming.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5\" shock body with internal reservoir:\u003c\/strong\u003e increased piston surface area and reduced aeration for consistent damping\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1.25–3\" adjustable lift height:\u003c\/strong\u003e threaded body allows on-vehicle ride-height tuning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e6061 aircraft-grade aluminum CNC components:\u003c\/strong\u003e machined for dimensional accuracy and weight reduction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCAD-plated shock bodies with 7\/8\" shafts:\u003c\/strong\u003e corrosion resistance and side-load durability\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFK rod end bearings:\u003c\/strong\u003e extended service life and minimal deflection under load\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully rebuildable and re-tunable:\u003c\/strong\u003e serviceable without full replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2025–2026 Toyota 4Runner 4WD (length-optimized); also fits 2WD\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift Range\u003c\/td\u003e\n      \u003ctd\u003e1.25–3 inches (gasoline engine models; stock-equipped vehicle)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Body Diameter\u003c\/td\u003e\n      \u003ctd\u003e2.5 inches\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eReservoir Type\u003c\/td\u003e\n      \u003ctd\u003eInternal\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShaft Diameter\u003c\/td\u003e\n      \u003ctd\u003e7\/8 inch\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpring Material\u003c\/td\u003e\n      \u003ctd\u003eICON-engineered coil springs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBearing Type\u003c\/td\u003e\n      \u003ctd\u003eFK rod end bearings\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBody Material\u003c\/td\u003e\n      \u003ctd\u003e6061 aircraft-grade aluminum (CNC machined components); CAD-plated shock bodies\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003e58692\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShip Weight\u003c\/td\u003e\n      \u003ctd\u003e60 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThis coilover kit suits 2025–2026 Toyota 4Runner owners, 4WD or 2WD, who want a rebuildable, adjustable-height front suspension upgrade that supports larger tire fitment and improved off-road damping performance over the factory setup.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis kit is not compatible with 4Runner models equipped with Adaptive Variable Suspension (AVS).
