Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.\u003c\/p\u003e\n\n\u003ch2\u003eMore Travel, Less Bind\u003c\/h2\u003e\n\u003cp\u003eThe 2.5 Series front coilovers pair vehicle-specific valving with remote reservoirs that dissipate heat during sustained off-road use, maintaining consistent damping when stock shocks would fade. Height adjustability across the full 1.25–3\" range means the front ride height can be dialed in for the tire size and load rather than locked to a single lift figure. The front differential drop kit works alongside the coilover geometry to maximize available front suspension travel and keep CV joints within their safe operating angle, protecting driveline components on rough terrain while preserving the full range of wheel travel the coilovers are capable of.\u003c\/p\u003e\n\n\u003ch2\u003eGeometry Corrected at the Control Arm\u003c\/h2\u003e\n\u003cp\u003eThe tubular upper control arms replace the OE units with stronger steel construction and corrected front-end geometry, adding caster and improving clearance for suspension components at full travel. The ICON Delta Joint PRO (U.S. Pat. 10,731,700) replaces the OE ball joint with a serviceable, rebuildable unit offering 90 degrees of total articulation, allowing full bump and droop travel without the bind that limits OE-geometry arms at lifted ride heights. Polyurethane differential mounting bushings replace the softer OE units to reduce differential movement under load.\u003c\/p\u003e\n\n\u003ch2\u003eRear End Balanced Front to Back\u003c\/h2\u003e\n\u003cp\u003eDual-rate rear coil springs use a softer rate at ride height for on-road comfort and a firmer overload rate for bottoming resistance under load or off-road, while adding 0.75\" of rear lift for a level front-to-rear stance. Tubular rear lower links use dual-durometer greaseless bushings at one end and FK rod ends at the other, combining free articulation with effective isolation of road noise and vibration. The billet adjustable rear track bar re-centers the rear axle after the lift and allows fine length adjustment on the vehicle without removal or disassembly. The 2.0 Aluminum Series remote-reservoir rear shocks are valved to balance rear performance with the front coilovers.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5 Series front coilovers:\u003c\/strong\u003e remote reservoirs, vehicle-specific valving, CAD-plated bodies, 7\/8\" shafts, 1.25–3\" height adjustable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubular UCAs with Delta Joint PRO:\u003c\/strong\u003e corrected geometry, added caster, 90° articulation, serviceable and rebuildable (U.S. Pat. 10,731,700)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFront differential drop kit:\u003c\/strong\u003e maximizes CV operating angle and front wheel travel; includes polyurethane diff mounting bushings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-rate rear coil springs:\u003c\/strong\u003e 0.75\" rear lift, softer ride-height rate with firmer overload rate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubular rear lower links:\u003c\/strong\u003e dual-durometer greaseless bushings and FK rod ends for articulation and noise isolation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBillet adjustable rear track bar:\u003c\/strong\u003e re-centers rear axle; on-vehicle fine adjustment without removal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.0 Aluminum Series rear shocks:\u003c\/strong\u003e remote reservoirs, 5\/8\" shafts, vehicle-specific valving\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\u003eFitment\u003c\/td\u003e\n      \u003ctd\u003e2025–2026 Toyota 4Runner 4WD (gasoline engine)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront lift range\u003c\/td\u003e\n      \u003ctd\u003e1.25–3\" over stock (height adjustable)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear lift\u003c\/td\u003e\n      \u003ctd\u003e0.75\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront shock series\u003c\/td\u003e\n      \u003ctd\u003e2.5 Series remote-reservoir coilovers, CAD-plated bodies, 7\/8\" shafts\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear shock series\u003c\/td\u003e\n      \u003ctd\u003e2.0 Aluminum Series remote-reservoir shocks, 5\/8\" shafts\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eUCA joint\u003c\/td\u003e\n      \u003ctd\u003eICON Delta Joint PRO, serviceable and rebuildable, 90° articulation (U.S. Pat. 10,731,700)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear spring type\u003c\/td\u003e\n      \u003ctd\u003eDual-rate coil springs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOEM wheels and tires\u003c\/td\u003e\n      \u003ctd\u003eCompatible\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended aftermarket wheels\u003c\/td\u003e\n      \u003ctd\u003e17×8.5 with 6.32\" backspace \/ 40mm offset; or ICON Alloys 18×9 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\u003e33×11.50\" (larger tires may fit but require fender trimming and modifications)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping weight\u003c\/td\u003e\n      \u003ctd\u003e209 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK53404T\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 system suits 2025–2026 Toyota 4Runner 4WD owners running a gasoline engine who want a complete, geometry-corrected suspension upgrade with adjustable front lift, increased wheel travel, and balanced front-to-rear damping for mixed on-road and off-road use.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis system does not fit 4Runner models equipped with Adaptive Variable Suspension (AVS).

Advertised lift heights are based on gasoline-engine models at stock weight; hybrid powertrain fitment is not confirmed for this kit.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWill OEM wheels and tires still fit after installing this system?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eOEM wheels and tires are confirmed compatible with this Stage 4 Tubular system. For aftermarket fitments, ICON recommends a 17×8.5 wheel with 6.32\" backspace and 40mm offset, or an ICON Alloys 18×9 with 6.6\" backspace and 40mm offset, paired with a 33×11.50\" tire. Larger tires may fit but will require fender trimming and modifications.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat does the Delta Joint PRO do that the OEM ball joint doesn't?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe ICON Delta Joint PRO (U.S. Pat. 10,731,700) is a serviceable, rebuildable replacement for the OEM ball joint offering 90 degrees of total articulation. At lifted ride heights, the OEM ball joint can bind before the suspension reaches full bump or droop travel; the Delta Joint PRO eliminates that bind, allowing the coilovers to use their full range of travel.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDoes installing this system require recalibrating any vehicle electronics?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. Advanced Driver Assistance Systems (ADAS) require recalibration after installation of this Stage 4 Tubular system. This is a vehicle-level requirement that applies regardless of which suspension components are installed; a qualified shop with the appropriate calibration equipment should perform this step.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eAre the shocks serviceable after installation?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eAll shocks included in this Stage 4 Tubular system are fully serviceable. The front 2.5 Series coilovers and rear 2.0 Aluminum Series shocks can be rebuilt rather than replaced, which extends the usable life of the system over time.\u003c\/p\u003e","brand":"ICON Vehicle Dynamics","offers":[{"title":"Default Title","offer_id":50629898469446,"sku":"K53404T","price":5214.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2203\/1686\/files\/ab8ce81177ed4c19074349b02f057487-sq.jpg?v=1791952096","url":"https:\/\/terrainvault.com\/products\/icon-stage-4-tubular-1-25-3-lift-suspension-system-for-2025-2026-toyot","provider":"TerrainVault","version":"1.0","type":"link"}
