Springs are rated for diesel engines only. This system fits single rear wheel models only and does not fit 2024 or later model years.\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. We email tracking as soon as your order ships.\u003c\/p\u003e\n\n\u003ch2\u003eBolt-In Coilover Conversion with Adjustable Ride Height\u003c\/h2\u003e\n\u003cp\u003eThe 2.5 VS Series remote reservoir coilovers install into the factory coil bucket location (no cutting or custom fabrication required) and deliver 2.5–3 inches of front lift on a stock-equipped vehicle. Ride height is user-adjustable within that range, so the truck can be set for loaded work duty or unladen trail use without swapping components. The coilover conversion also opens the door for a secondary shock if more damping capacity is needed later; contact ICON for compatible options.\u003c\/p\u003e\n\n\u003ch2\u003eVehicle-Specific Valving and External Tunability\u003c\/h2\u003e\n\u003cp\u003eFront coilovers use Continuous Damping Control Valve (CDCV) technology with vehicle-specific valving and FK Rod End bearings. The 2.5 Aluminum Series CDCV piggyback rear shocks offer 10 externally selectable damping settings, ranging from soft to firm, so rear ride character can be dialed in without tools beyond the adjustment knob. CAD-plated coilover shock bodies with 7\/8-inch shafts resist corrosion, and the one-piece impact-extruded aluminum cylinders on the rear shocks provide a consistent finish over time. All shocks are fully rebuildable and revalveable.\u003c\/p\u003e\n\n\u003ch2\u003eSteering Stability and Rear Compliance\u003c\/h2\u003e\n\u003cp\u003eA dual steering stabilizer kit with two 2.0 Aluminum Series stabilizers in a dual-opposing configuration reduces steering wander under load and on rough surfaces. The adjustable track bar corrects axle placement geometry that shifts when the front is lifted. Rear leaf spring expansion packs with a 1-inch cast block kit add rear lift on F-250 models (the same blocks lower F-350 rear ride height by 0.5 inches compared to stock); U-bolts and a 2-inch rear bump stop spacer kit are included. ICON-engineered coil and leaf springs carry a lifetime guarantee against sagging or breakage.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5 VS RR CDCV bolt-in coilovers:\u003c\/strong\u003e install in OE coil bucket, 2.5–3\" adjustable front lift\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual 2.0 Aluminum Series steering stabilizers:\u003c\/strong\u003e dual-opposing kit for smooth wheel control\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable track bar:\u003c\/strong\u003e corrects axle placement after front lift\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5 VS CDCV piggyback rear shocks:\u003c\/strong\u003e 10 external damping settings, soft to firm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf spring expansion packs with U-bolts and blocks:\u003c\/strong\u003e more compliant rear ride, reduced axle wrap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLifetime spring guarantee:\u003c\/strong\u003e ICON-engineered coil and leaf springs guaranteed against sagging or breakage\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\u003e2023 Ford F-250\/F-350 Super Duty 4WD, single rear wheel models only\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift Range\u003c\/td\u003e\n      \u003ctd\u003e2.5–3\" (stock-equipped vehicle); 1.5–2\" on Tremor package\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shock Diameter\u003c\/td\u003e\n      \u003ctd\u003e2.5\" remote reservoir\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shock Type\u003c\/td\u003e\n      \u003ctd\u003e2.5\" Aluminum Series CDCV piggyback reservoir\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Damping Adjustment\u003c\/td\u003e\n      \u003ctd\u003e10 external settings\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Shaft Diameter\u003c\/td\u003e\n      \u003ctd\u003e7\/8\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpring Rating\u003c\/td\u003e\n      \u003ctd\u003eDiesel engines only\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Block Height\u003c\/td\u003e\n      \u003ctd\u003e1\" cast block (adds 0.5\" rear lift on F-250; lowers F-350 rear 0.5\" vs. stock)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK63164L\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e334 lb\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 Tires\u003c\/td\u003e\n      \u003ctd\u003e35\" × 12.50\" (37\" × 12.50\" may fit with fender trimming)\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 owners of a 2023 Ford F-250 or F-350 Super Duty 4WD with a diesel engine and single rear wheels who want a 2.5–3-inch front lift with meaningfully improved damping for towing, job-site use, or off-road driving.

Trucks with the Tremor package will see a reduced front lift range of 1.5–2 inches. The brake line kit, track bar bump steer bracket, and ADAS recalibration are not included and are required or recommended separately; trucks with Dynamic Bending Headlamps or Onboard Scales require additional parts not included in this kit.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes this system fit my 2024 Ford F-250 Super Duty?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe ICON Stage 4 Coilover Conversion System K63164L is confirmed for 2023 Ford F-250\/F-350 Super Duty 4WD only.

Trucks equipped with the Tremor package will see a reduced front lift range of approximately 1.5–2 inches over stock due to the Tremor's taller factory ride height.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eAre the springs in this kit compatible with a gas-engine Super Duty?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The ICON-engineered coil and leaf springs included in this Stage 4 system are rated for diesel engines only. A gas-engine 2023 F-250\/F-350 Super Duty requires a different spring specification; this kit should not be used on gas-powered trucks.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat additional parts are needed to complete the installation?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eICON recommends the track bar bump steer bracket (part 64039) to correct bump steer geometry; it is sold separately. Trucks with Dynamic Bending Headlamps or Onboard Scales require the F-Series sensor mount kit (part 611081), also sold separately. ADAS recalibration is required after installation. A braided stainless brake line kit (part 61111) is optional but not required for a complete install.\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.
