The complete kit is engineered for on-road driving, towing, and mild off-road use including job-site and washboard gravel roads. Lift height is based on a 4WD Crew Cab Gas configuration; trucks with the Tremor package will see approximately 1.5 inches of front lift over stock.\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\u003eTuned as a Complete Package\u003c\/h2\u003e\n\u003cp\u003eBecause the coil springs and shocks are developed and tested together, the Stage 1 system delivers a consistent, predictable ride rather than the compromises that come from mixing unmatched components. The dual-rate spring design transitions between a softer initial rate for everyday comfort and a firmer rate under load, which matters when the truck is hauling a payload or pulling a trailer. ICON 2.0 Aluminum Series shocks carry vehicle-specific valving, so the damping is calibrated for the F-250\/F-350 platform rather than a generic heavy-duty tune.\u003c\/p\u003e\n\n\u003ch2\u003eApproximately 25% More Front Wheel Travel\u003c\/h2\u003e\n\u003cp\u003eThe Stage 1 system provides approximately 25 percent more front wheel travel over the factory suspension. That additional travel keeps the front tires in contact with uneven terrain longer, reducing the jarring that transfers into the cab on rough job-site roads or gravel. For daily drivers and work trucks, the practical result is less fatigue on long days and better steering feel when the road surface changes.\u003c\/p\u003e\n\n\u003ch2\u003eRebuildable Shocks and Long-Term Guarantees\u003c\/h2\u003e\n\u003cp\u003eICON 2.0 Aluminum Series shocks feature corrosion-resistant anodized bodies and 5\/8-inch shafts. The shocks are fully rebuildable and revalvable, so the system can be serviced and retuned rather than replaced outright. The coil springs carry a lifetime guarantee against breakage or sag, and fabricated components carry a lifetime guarantee against breakage or manufacturer defect.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-rate coil springs:\u003c\/strong\u003e optimized for gasoline-engine F-250\/F-350 trucks; lifetime guarantee against breakage or sag\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eICON 2.0 Aluminum Series shocks:\u003c\/strong\u003e vehicle-specific tune, anodized bodies, 5\/8\" shafts, front and rear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAlignment cams included:\u003c\/strong\u003e front cams supplied with the spring kit for post-lift alignment\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApproximately 25% more front wheel travel:\u003c\/strong\u003e over factory suspension\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully rebuildable and revalvable shocks:\u003c\/strong\u003e serviceable without full replacement\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOEM wheels and tires compatible:\u003c\/strong\u003e factory fitment works with this lift\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\u003eK62591\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2023 Ford F-250 \/ F-350 Super Duty 4WD Gas\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift Height\u003c\/td\u003e\n      \u003ctd\u003e2.5\" (4WD Crew Cab Gas); 1.5\" over stock with Tremor package\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shock Compatibility\u003c\/td\u003e\n      \u003ctd\u003e0–2\" rear lift over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Series\u003c\/td\u003e\n      \u003ctd\u003eICON 2.0 Aluminum Series (VS IR)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Shaft Diameter\u003c\/td\u003e\n      \u003ctd\u003e5\/8\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSystem Components\u003c\/td\u003e\n      \u003ctd\u003e62513: Front 2.5\" Gas Dual Rate Spring Kit w\/ Cams (×1); 66512: Front 2.0 VS IR Shocks (×2); 66516: Rear 0–2\" 2.0 VS IR Shocks (×2)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Tires\u003c\/td\u003e\n      \u003ctd\u003e35\" × 12.50\" (larger tires may fit but require fender trimming)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Wheels\u003c\/td\u003e\n      \u003ctd\u003eICON Alloys 17×8.5\" (5\" backspace \/ 6mm offset); 18×9\" (5.25\" backspace \/ 6mm offset); 20×9\" (5.25\" backspace \/ 6mm offset)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eKit Weight (shipped)\u003c\/td\u003e\n      \u003ctd\u003e81 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 system suits owners of a 2023 Ford F-250 or F-350 Super Duty 4WD with a gasoline engine who want a 2.5-inch front lift, improved ride quality, and a shock-and-spring package tuned for on-road, towing, and light off-road use.

Trucks with the Tremor package will achieve approximately 1.5 inches of front lift over stock rather than 2.5 inches. Advanced Driver Assistance Systems (ADAS) require recalibration after installation. An adjustable track bar may be needed to realign the axle; ICON track bar bracket (part 64039) is sold separately.

It does not fit 2024 or later model-year Super Duty trucks. A separate ICON system would be required for 2024 applications.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWill this system work with a diesel engine?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The dual-rate coil springs in this Stage 1 kit are rated for gasoline-engine F-250\/F-350 trucks. A diesel-rated spring kit is a different product; this system should not be installed on diesel-powered Super Duty trucks.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat is included in the kit?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Stage 1 kit includes one front 2.5-inch gas dual-rate spring kit with alignment cams (part 62513), two front ICON 2.0 VS IR shocks (part 66512), and two rear ICON 2.0 VS IR shocks (part 66516). The optional track bar bracket and braided stainless brake line kit are sold separately.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDo I need to recalibrate my truck's safety systems after installation?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. The ICON Stage 1 Suspension System requires recalibration of Advanced Driver Assistance Systems (ADAS) after installation. This applies to any Super Duty equipped with features such as lane-keep assist, automatic emergency braking, or adaptive cruise control that rely on sensors affected by ride-height changes.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eCan I keep my factory wheels and tires?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. OEM wheels and tires are compatible with this 2.5-inch Stage 1 lift. For owners upgrading to aftermarket tires, ICON recommends a 35-inch by 12.50-inch tire; larger sizes may fit but could require fender trimming or other modifications.\u003c\/p\u003e","brand":"ICON Vehicle Dynamics","offers":[{"title":"Default Title","offer_id":50629599395910,"sku":"K62591","price":1288.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2203\/1686\/files\/13b9f992aad33bf3e1d872a19a1be5e0-sq.jpg?v=1791948162","url":"https:\/\/terrainvault.com\/products\/icon-stage-1-suspension-system-for-2023-ford-f-250-f-350-super-duty-4w","provider":"TerrainVault","version":"1.0","type":"link"}
