The system ships as seven matched components tuned together as a package.\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.

On a loaded tow rig or a truck running rough construction-site roads, shock fade from heat buildup is a real problem; the added reservoir capacity keeps fluid temperatures lower and damping behavior more predictable mile after mile. Shocks are fully serviceable, so they can be rebuilt rather than replaced when they eventually wear.\u003c\/p\u003e\n\n\u003ch2\u003eFront Geometry Corrected, Not Just Lifted\u003c\/h2\u003e\n\u003cp\u003eLifting a Super Duty without addressing front geometry shifts caster and throws axle centering off. The Stage 3 system includes an adjustable track bar with an FK rod end for on-vehicle axle centering and application-specific alignment cams to restore proper caster after the lift. Correcting these angles matters for straight-line stability, tire wear, and steering feel, particularly on a truck used for towing where handling predictability is not optional.\u003c\/p\u003e\n\n\u003ch2\u003eRear Suspension Tuned for Compliance and Axle Control\u003c\/h2\u003e\n\u003cp\u003eThe rear of the system uses leaf spring expansion packs, U-bolts, a 1-inch cast block kit, and a 2-inch rear bump stop spacer kit to improve compliance and reduce axle wrap under acceleration. On an F-250, the rear block adds 0.5 inches of rear lift over stock. On an F-350, the same block lowers rear ride height by 0.5 inches compared to stock. Towing capacity is not reduced compared to stock, and springs carry a lifetime guarantee against sagging or breaking.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable front lift:\u003c\/strong\u003e 2.5 Series remote reservoir coilovers provide 2.5–3 inches of ride-height adjustment over stock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGeometry correction included:\u003c\/strong\u003e adjustable track bar with FK rod end and application-specific alignment cams ship with the kit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRear compliance package:\u003c\/strong\u003e leaf spring expansion packs, U-bolts, 1-inch cast blocks, and 2-inch bump stop spacers address axle wrap and ride quality\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eNo driveshaft modifications required\u003c\/strong\u003e\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOEM wheels and tires fit\u003c\/strong\u003e without modification\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully serviceable shocks:\u003c\/strong\u003e front and rear units can be rebuilt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProp 65 Warning:\u003c\/strong\u003e this product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm\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\u003eK63193\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2011–2016 Ford F-250 \/ F-350 Super Duty, 4WD, single rear wheel only\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eEngine Compatibility (springs)\u003c\/td\u003e\n      \u003ctd\u003eDiesel engines only\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift Range\u003c\/td\u003e\n      \u003ctd\u003e2.5–3 inches over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lift Effect: F-250\u003c\/td\u003e\n      \u003ctd\u003e+0.5 inch over stock (replaces OE rear blocks)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lift Effect: F-350\u003c\/td\u003e\n      \u003ctd\u003e−0.5 inch vs. stock (replaces OE rear blocks)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shock Series\u003c\/td\u003e\n      \u003ctd\u003eICON 2.5 Series remote reservoir coilovers\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shock Series\u003c\/td\u003e\n      \u003ctd\u003eICON 2.5 Aluminum Series piggyback reservoir shocks\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e304 lb\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 (5.00\" 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\u003eRecommended Max Tire Size\u003c\/td\u003e\n      \u003ctd\u003e35×12.50 (larger 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 4WD 2011–2016 Ford F-250 or F-350 Super Duty trucks with single rear wheels and diesel engines who want 2.5–3 inches of front lift, improved ride compliance on rough terrain, and geometry correction, including trucks used regularly for towing.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis system does not fit F-350 Cab and Chassis models, two-wheel-drive Super Duty trucks, or dual rear wheel configurations.
