Trucks equipped with the Tremor package will see a front lift of approximately 1.5 inches over stock rather than the full 2.5 inches.\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 for Diesel Weight\u003c\/h2\u003e\n\u003cp\u003eDiesel-powered Super Dutys carry significantly more weight over the front axle than their gas counterparts, and a spring rate calibrated for that load makes a measurable difference in both daily driving and trail behavior. The dual-rate design opens with a softer initial rate for composed highway and pavement ride, then transitions to a firmer secondary rate as the spring compresses further, resisting bottoming on rough terrain without transmitting harshness at low inputs. The result is a front end that behaves predictably whether the truck is loaded or empty.\u003c\/p\u003e\n\n\u003ch2\u003eGeometry Corrected from the Start\u003c\/h2\u003e\n\u003cp\u003eLifting a solid-front-axle truck changes caster angle, which affects steering return-to-center and stability at speed. The included caster cam kit addresses that geometry change at installation rather than leaving it as a follow-up item. One application note applies: the included cams are not compatible with models that have a manual locking front hub on the driver side only. Those configurations require aftermarket radius arms, a 4-link conversion, or an upgrade to a passenger-side manual locking hub before the cams can be used.\u003c\/p\u003e\n\n\u003ch2\u003eBolt-On Installation, No Cutting\u003c\/h2\u003e\n\u003cp\u003eThe kit installs without cutting or welding. A dual-stage semi-gloss powder coat provides corrosion resistance for long-term durability in road-salt and off-road environments. After installation, Advanced Driver Assistance Systems (ADAS) require recalibration, and this applies to all equipped trucks regardless of installer. An adjustable track bar (ICON part 64039) is separately recommended to correct bump steer geometry and realign the axle laterally; a braided stainless brake line kit (ICON part 61111) is optional for owners who prefer not to bend the factory steel lines.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5\" front lift height:\u003c\/strong\u003e based on 4WD crew cab diesel configuration\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-rate spring design:\u003c\/strong\u003e softer initial rate for on-road comfort, firmer secondary rate for off-road bottoming resistance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaster cam kit included:\u003c\/strong\u003e corrects caster angle for the new ride height\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-stage semi-gloss powder coat:\u003c\/strong\u003e corrosion-resistant finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% bolt-on system:\u003c\/strong\u003e no cutting or welding required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLifetime warranty:\u003c\/strong\u003e against sagging and 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, Diesel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift Height\u003c\/td\u003e\n      \u003ctd\u003e2.5\" (based on 4WD crew cab diesel; Tremor package yields approx. 1.5\" over stock)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpring Design\u003c\/td\u003e\n      \u003ctd\u003eDual rate, front coil springs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFinish\u003c\/td\u003e\n      \u003ctd\u003eDual-stage semi-gloss powder coat\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eIncluded Hardware\u003c\/td\u003e\n      \u003ctd\u003eCoil springs, caster cam kit\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003e62512\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e64 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 kit suits owners of 2023 Ford F-250 or F-350 Super Duty trucks with 4WD and a diesel engine who want 2.5 inches of front lift, improved on- and off-road ride quality, and the ability to run larger tires. Factory wheels and tires are compatible; recommended aftermarket fitments include 17x8.5-inch wheels with 5-inch backspace, 18x9-inch with 5.25-inch backspace, and 20x9-inch with 5.25-inch backspace, paired with up to 35x12.50-inch tires (larger tires may require fender trimming).\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis kit does not fit F-450 or F-550 models, 2WD configurations, or gas-engine Super Dutys. The included caster cams are not compatible with trucks that have a manual locking front hub on the driver side only; those vehicles require aftermarket radius arms, a 4-link conversion, or an upgrade to a passenger-side manual locking hub as an alternative alignment solution. ADAS recalibration is required after installation on all equipped trucks. An adjustable track bar and extended brake lines are not included and may be needed depending on the build.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes this kit fit a gas-engine F-250 or F-350?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The ICON Dual Rate Coil Spring Kit (SKU 62512) is rated for diesel engines only. The spring rates are calibrated for the additional front-axle weight of a diesel powertrain; a gas-engine Super Duty requires a different spring kit.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWill this kit work on a 2023 F-250 with the Tremor package?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes, but the front lift height on a Tremor-equipped truck will be approximately 1.5 inches over stock rather than the full 2.5 inches, because the Tremor package already raises the factory ride height. All other kit components and installation steps remain the same.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eAre shocks included, or do I need to purchase them separately?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eShocks are not included in this kit. The ICON Dual Rate Coil Spring Kit supplies the front coil springs and caster cam kit only. ICON notes that increased wheel travel is realized when these springs are paired with compatible ICON shocks, which are sold separately.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDo I need an adjustable track bar after installing these springs?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eAn adjustable track bar is not included but is recommended. Lifting the front axle can shift it laterally, and ICON recommends their track bar bracket (part 64039) to correct bump steer geometry and restore proper axle alignment after the coil spring installation.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDo my truck's driver-assistance systems need to be recalibrated after installation?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. Trucks equipped with Advanced Driver Assistance Systems (ADAS) require recalibration after installing the ICON Dual Rate Coil Spring Kit. This applies regardless of who performs the installation and should be completed before returning the truck to normal use.\u003c\/p\u003e\n\n\u003cp\u003eWARNING: This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm (California Proposition 65).\u003c\/p\u003e","brand":"ICON Vehicle Dynamics","offers":[{"title":"Default Title","offer_id":50628476731462,"sku":"62512","price":495.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2203\/1686\/files\/05e62d181e33be8101eff7379a3611ec_78c52475-2325-4e9e-a885-7dd-sq.jpg?v=1791944446","url":"https:\/\/terrainvault.com\/products\/icon-vehicle-dynamics-2023-ford-f-250-f-350-super-duty-4wd-diesel-2-5","provider":"TerrainVault","version":"1.0","type":"link"}
