The kit centers on a 2.5\" diameter shock body paired with a remote reservoir and ICON's Compression Damping Control Valve (CDCV) for external tune adjustment. SKU 58795C ships as a front kit; a compatible 2.5 Aluminum Series CDCV rear shock set is available separately for balanced front-to-rear performance.\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. Lead times vary by part and some items are built to order, so please allow extra time.

On 4WD models, the kit is designed to pair with ICON's front differential drop (part #55160, sold separately), which together yield the maximum wheel travel the front end can achieve. More travel means the suspension can absorb larger obstacles without the wheel losing contact with the ground, which translates directly to traction and vehicle control on uneven terrain.\u003c\/p\u003e\n\n\u003ch2\u003eRemote Reservoir and CDCV: Heat Management and Tuning Precision\u003c\/h2\u003e\n\u003cp\u003eThe remote reservoir increases total shock oil volume and expands the heat-dissipation surface area, reducing the risk of overheating and cavitation during sustained hard use. Overheating and cavitation are the mechanism behind damper fade on trail or high-speed desert runs. The CDCV adds 10 positions of external compression damping adjustment, letting the driver dial the suspension for street commuting, slow technical crawling, or high-speed off-road running without disassembling the shock. Fluid flow under compression is controlled at the valve, so changes are precise and repeatable.\u003c\/p\u003e\n\n\u003ch2\u003eConstruction Built for Longevity and Serviceability\u003c\/h2\u003e\n\u003cp\u003eShock bodies are CAD-plated for corrosion resistance and machined from 6061 aircraft-grade aluminum. The 7\/8\" diameter shaft and FK rod end bearings are specified for extended service life and minimal deflection under load. The entire assembly is fully rebuildable and re-tunable, so the kit can be serviced and revalved rather than replaced when wear or a change in use case demands it.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5\" shock body with remote reservoir:\u003c\/strong\u003e increased oil volume and heat dissipation for fade resistance under hard use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCDCV with 10-position external adjustment:\u003c\/strong\u003e compression damping tunable without disassembly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1.25–3\" lift height adjustability:\u003c\/strong\u003e accommodates larger wheel and tire combinations (gasoline engine, stock vehicle weight)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e6061 aircraft-grade aluminum CNC components:\u003c\/strong\u003e CAD-plated shock bodies with 7\/8\" diameter shafts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFK rod end bearings:\u003c\/strong\u003e extended longevity and minimal deflection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully rebuildable and re-tunable:\u003c\/strong\u003e serviceable in the field or at a shop 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\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003e58795C\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2025–2026 Toyota 4Runner 4WD\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift Range\u003c\/td\u003e\n      \u003ctd\u003e1.25–3\" (gasoline engine, stock vehicle weight)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Body Diameter\u003c\/td\u003e\n      \u003ctd\u003e2.5\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShaft Diameter\u003c\/td\u003e\n      \u003ctd\u003e7\/8\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCompression Adjustment\u003c\/td\u003e\n      \u003ctd\u003e10 positions (external CDCV)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaterial\u003c\/td\u003e\n      \u003ctd\u003e6061 aircraft-grade aluminum; CAD-plated shock bodies\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBearings\u003c\/td\u003e\n      \u003ctd\u003eFK rod end\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e58 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Wheels (17\")\u003c\/td\u003e\n      \u003ctd\u003e17x8.5 with 6.32\" backspace \/ 40mm offset\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Wheels (18\")\u003c\/td\u003e\n      \u003ctd\u003e18x9 with 6.6\" backspace \/ 40mm offset\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Tires\u003c\/td\u003e\n      \u003ctd\u003e33\" x 11.50\" (larger tires may require fender trimming)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eUPC\u003c\/td\u003e\n      \u003ctd\u003e840103435176\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 kit suits 2025–2026 Toyota 4Runner 4WD owners running a gasoline engine who want 1.25–3\" of front lift with externally adjustable compression damping and remote-reservoir heat management for mixed street and off-road use.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis kit is not compatible with 4Runner models equipped with Adaptive Variable Suspension (AVS). It is length-optimized for 4WD models; 2WD owners seeking maximum wheel travel should consider ICON's 2WD-specific part numbers. The front differential drop (part #55160) is required for 4WD installation and is sold separately. ICON Delta Joint Pro front upper control arms are recommended for lifts above 2\" to maintain proper wheel alignment and are also sold separately. Advanced Driver Assistance Systems (ADAS) require recalibration after installation. Advertised lift heights apply to stock-weight vehicles; added accessories will alter the lift range.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eIs the front differential drop included with this coilover kit?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe front differential drop is not included. ICON front differential drop part #55160 is required for 4WD 4Runner installations and must be purchased separately. The coilover kit (SKU 58795C) covers the front shocks, springs, and CDCV hardware only.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDo I need new upper control arms with this kit?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eICON recommends Delta Joint Pro front upper control arms for lifts above 2\" to maintain proper wheel alignment geometry.
