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\u003eRemote Reservoirs Front and Rear\u003c\/h2\u003e\n\u003cp\u003eThe 2.5 Series front coilovers and 2.5 Aluminum Series rear shocks both use remote reservoirs to increase shock oil volume and heat-dissipation surface area. Under sustained hard use (repeated high-speed whoops, loaded trail runs, or back-to-back descents), that added capacity resists the overheating and cavitation that cause damper fade, so the suspension continues to perform at the end of a long day the same way it did at the start.\u003c\/p\u003e\n\n\u003ch2\u003eCorrected Geometry Through the Full Travel Range\u003c\/h2\u003e\n\u003cp\u003eThe tubular upper control arms are built with corrected front-end geometry and added caster, improving component clearance and drivability at lifted ride heights. 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 bind. The front differential drop kit combines drop brackets and polyurethane differential mounting bushings to maximize available front suspension travel and prevent CV bind at the coilover lengths this system uses.\u003c\/p\u003e\n\n\u003ch2\u003eRear Balance and On-Vehicle Adjustability\u003c\/h2\u003e\n\u003cp\u003eDual-rate rear coil springs use a softer ride-height rate for on-road comfort and a firmer overload rate for bottoming resistance off-road, producing 0.75\" of rear lift for a level front-to-rear stance. The billet adjustable rear track bar re-centers the rear axle after the lift and uses double adjuster rod end threads for fine length adjustment without removing or disassembling the bar. The 2.5 Aluminum Series rear shocks carry vehicle-specific valving tuned to balance 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, CAD-plated bodies, 7\/8\" shafts, 1.25–3\" height adjustability\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubular UCAs with Delta Joint PRO:\u003c\/strong\u003e patented (U.S. Pat. 10,731,700), 90° articulation, serviceable and rebuildable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFront differential drop kit:\u003c\/strong\u003e drop brackets plus polyurethane bushings to maximize travel and prevent CV bind\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\u003eBillet adjustable rear track bar:\u003c\/strong\u003e re-centers rear axle, on-vehicle fine adjustment without disassembly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5 Aluminum Series rear shocks:\u003c\/strong\u003e remote reservoirs, integrated bump zones, 7\/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\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 (gasoline engine models)\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\u003eICON 2.5 Series coilover, remote reservoir, CAD-plated body, 7\/8\" shaft\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear shock series\u003c\/td\u003e\n      \u003ctd\u003eICON 2.5 Aluminum Series, remote reservoir, integrated bump zones, 7\/8\" shaft\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eUpper control arms\u003c\/td\u003e\n      \u003ctd\u003eTubular, with ICON Delta Joint PRO (U.S. Pat. 10,731,700), 90° articulation\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear springs\u003c\/td\u003e\n      \u003ctd\u003eDual-rate coil, vehicle-specific\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear track bar\u003c\/td\u003e\n      \u003ctd\u003eBillet aluminum, on-vehicle adjustable\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOEM wheel\/tire fitment\u003c\/td\u003e\n      \u003ctd\u003eYes\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 sizes may fit but require fender trimming and modifications)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShocks serviceable\u003c\/td\u003e\n      \u003ctd\u003eYes, fully serviceable\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping weight\u003c\/td\u003e\n      \u003ctd\u003e192 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK53406T\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003e⚠️ California Proposition 65 Warning: This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm.\u003c\/p\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 gasoline engines who want a complete, matched front-and-rear suspension upgrade with 1.25–3\" of adjustable front lift, improved wheel travel, and the ability to run 33\" tires on recommended aftermarket wheels without geometry compromise.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis system does not fit 2WD 4Runner models, hybrid powertrains, or any 4Runner equipped with Adaptive Variable Suspension (AVS).

Adding accessories or cargo weight will reduce the realized lift height.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eAre the shocks in this system rebuildable?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. Both the 2.5 Series front coilovers and the 2.5 Aluminum Series rear shocks in this Stage 6 system are fully serviceable. The tubular upper control arm's Delta Joint PRO ball joint is also serviceable and rebuildable, extending the usable life of the entire assembly.\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 wheel and tire fitment is confirmed with this Stage 6 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.
