The kit is a 100% bolt-on replacement and is covered by a lifetime guarantee against sagging and breakage.\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\u003eProgressive Rate Where It Counts\u003c\/h2\u003e\n\u003cp\u003eThe dual-rate coil design uses a softer initial spring rate during everyday driving, which smooths out pavement imperfections without the harsh, oversprung feel common to lifted trucks. As the suspension compresses further under load or rough terrain, the spring transitions to a firmer secondary rate that resists bottoming out. The result is a front end that rides comfortably on the highway and stays composed on washboard or rocky trails without requiring a compromise between the two.\u003c\/p\u003e\n\n\u003ch2\u003eCorrosion Resistance Built In\u003c\/h2\u003e\n\u003cp\u003eEach spring receives a dual-stage, semi-gloss powder coat finish that protects against road salt, mud, and moisture. Suspension components that see regular off-pavement use are especially vulnerable to corrosion, and the finish is applied before the springs ship, so no additional prep or coating is needed at install.\u003c\/p\u003e\n\n\u003ch2\u003eBolt-On Installation\u003c\/h2\u003e\n\u003cp\u003eThe kit is designed as a direct replacement for the factory front coil springs with no cutting or welding required. Caster correction is required for this lift height and must be sourced separately: appropriate caster cams, an aftermarket radius arm kit, or a 4-link conversion are all options. An adjustable track bar is also recommended to realign the front axle laterally. Advanced Driver Assistance Systems (ADAS) require recalibration after installation.\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 gas configuration\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-rate spring design\u003c\/strong\u003e: softer initial rate for comfort, firmer secondary rate for bottoming resistance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-stage semi-gloss powder coat\u003c\/strong\u003e: corrosion-resistant finish applied at the factory\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% bolt-on fitment\u003c\/strong\u003e, direct replacement for factory front coil springs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLifetime guarantee\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\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003e62517\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift Height\u003c\/td\u003e\n      \u003ctd\u003e2.5\" (4WD crew cab gas; Tremor package: 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\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\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e62 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2023-2026 Ford F-250, F-350, F-450, F-550 Super Duty, 4WD, gasoline engine only\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFactory Wheels\/Tires\u003c\/td\u003e\n      \u003ctd\u003eCompatible\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Tire\u003c\/td\u003e\n      \u003ctd\u003e35\" x 12.50\" (larger tires may require 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 kit suits owners of 2023-2026 Ford F-250, F-350, F-450, or F-550 Super Duty trucks with 4WD and a gasoline engine who want 2.5 inches of front lift with improved on- and off-road ride quality over the factory springs.
