The kit is a 100% bolt-on system and is available for the 2023–2026 model year range only in the gas-engine, 4WD configuration.\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.

As the suspension compresses further under load or rough terrain, the spring transitions to a firmer secondary rate that resists bottoming out. That progression means the same springs that ride comfortably on the highway still have the resistance needed when the truck is loaded or the trail gets rough, without swapping hardware between uses.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt to Resist Corrosion and Sag\u003c\/h2\u003e\n\u003cp\u003eEach spring receives a dual-stage, semi-gloss powder-coat finish for corrosion resistance. ICON backs these springs with a lifetime warranty against sagging and breakage, so the lift height set at installation is the lift height the truck keeps over its service life.\u003c\/p\u003e\n\n\u003ch2\u003eBolt-On Installation, Larger Tire Clearance\u003c\/h2\u003e\n\u003cp\u003eThe kit installs without cutting or welding. When paired with ICON shocks, the added lift also increases available wheel travel and creates clearance for larger tires. ICON's technical data lists 37x12.50-inch tires as fitting without fender modification. ADAS (Advanced Driver Assistance Systems) recalibration is required after installation.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4.5-inch lift:\u003c\/strong\u003e raises ride height 4.5 inches over stock on standard Super Duty 4WD gas models (3.5 inches on Tremor package trucks)\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\u003eGas-engine-specific spring rates:\u003c\/strong\u003e spring rates are calibrated for gasoline-engine F-250\/F-350 trucks only\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-stage semi-gloss powder coat:\u003c\/strong\u003e corrosion-resistant finish on each spring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% bolt-on system:\u003c\/strong\u003e no cutting or welding required for installation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLifetime warranty:\u003c\/strong\u003e covered 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\u003e2023–2026 Ford F-250 \/ F-350 Super Duty, 4WD, Gas engine\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift Height\u003c\/td\u003e\n      \u003ctd\u003e4.5 inches over stock (3.5 inches on Tremor package trucks)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePosition\u003c\/td\u003e\n      \u003ctd\u003eFront\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpring Design\u003c\/td\u003e\n      \u003ctd\u003eDual rate\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\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003e64013\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e75 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 2023–2026 Ford F-250 or F-350 Super Duty trucks with 4WD and a gasoline engine who want 4.5 inches of front lift, improved wheel travel when paired with ICON shocks, and clearance for tires up to 37x12.50 inches without fender modification.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis kit does not fit diesel-engine Super Duty trucks, 2WD models, or any model year outside 2023–2026. Tremor package trucks will see 3.5 inches of lift rather than 4.5 inches. A braided stainless brake line upgrade requires a separate brake line kit (ICON Part 61110, sold separately). Tires larger than 37x12.50 inches may require fender trimming and additional modifications.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes this kit fit diesel-powered F-250 or F-350 trucks?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The ICON Dual Rate Front Coil Spring Kit (SKU 64013) is engineered with spring rates specific to gasoline-engine Super Duty trucks. Diesel-engine F-250 and F-350 models are not a supported fitment for this kit.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eHow much lift will a Tremor package truck get?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eOn a 2023–2026 Ford F-250 or F-350 equipped with the Tremor package, these coil springs produce approximately 3.5 inches of front lift over stock rather than the standard 4.5 inches, due to differences in the Tremor's factory suspension geometry.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDo I need to recalibrate my truck's safety systems after installing these springs?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. ICON specifies that Advanced Driver Assistance Systems (ADAS) must be recalibrated after installing these coil springs on a 2023–2026 Super Duty. This typically requires a visit to a dealer or a shop with the appropriate calibration equipment.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWill my factory wheels and tires still fit after installation?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. ICON's technical data confirms factory wheels and tires fit with this kit installed. For aftermarket fitments, ICON recommends 17x8.5-inch wheels with 5-inch backspace, 18x9-inch wheels with 5.25-inch backspace, or 20x9-inch wheels with 5.25-inch backspace, paired with tires up to 37x12.50 inches without fender modification.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eIs a brake line upgrade included with this kit?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The ICON Dual Rate Front Coil Spring Kit does not include a brake line upgrade. ICON recommends their Extended Stainless Brake Line Kit (Part 61110) as a separate purchase for buyers who want a braided stainless brake line upgrade to accompany the added lift.\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.
