This system fits single rear wheel models only and is not compatible with F-350 Cab and Chassis configurations.\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\u003eEngineered Lift Without Sacrificing Tow Capability\u003c\/h2\u003e\n\u003cp\u003eThe ICON dual rate coil springs provide 2.5 inches of front lift over stock without requiring driveshaft modifications or any cutting, drilling, or welding. Towing capacity is unchanged from stock, making this system a practical choice for trucks that haul regularly. Application-specific alignment cams are included to restore proper caster geometry after the lift, a step that many aftermarket systems leave to the owner to source separately.\u003c\/p\u003e\n\n\u003ch2\u003eMatched Front and Rear Shock Tuning\u003c\/h2\u003e\n\u003cp\u003eICON 2.0 Aluminum Series internal reservoir shocks are included for both the front and rear axle, tuned as a matched set with the springs. The internal reservoir extends shock stroke before fade sets in, which matters on washboard roads and rough construction-site terrain where repeated small hits accumulate heat quickly. The result is increased wheel travel and reduced body roll compared to stock, with a highway ride character that does not feel stiff or punishing.\u003c\/p\u003e\n\n\u003ch2\u003eRear Compliance and Axle Wrap Reduction\u003c\/h2\u003e\n\u003cp\u003eThe rear of the system uses ICON leaf spring expansion packs, a 1-inch cast block kit, a 2-inch rear bump stop spacer kit, and a 12-inch U-bolt kit. On F-250 models, this combination adds approximately 0.5 inches of rear lift over stock. On F-350 models, the rear ride height sits approximately 0.5 inches below stock due to differences in the OEM rear spring setup, a fitment-specific detail worth confirming before ordering. The expansion packs are designed to reduce axle wrap under acceleration and improve compliance on uneven surfaces.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5-inch front lift:\u003c\/strong\u003e ICON dual rate coil springs engineered for 2011–2016 F-250\/F-350 4WD Diesel applications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.0 Aluminum Series shocks:\u003c\/strong\u003e Match-tuned internal reservoir shocks front and rear for increased wheel travel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAlignment cams included:\u003c\/strong\u003e Application-specific cams correct caster geometry without additional parts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRear expansion packs:\u003c\/strong\u003e Leaf spring expansion packs, blocks, and U-bolts reduce axle wrap and improve rear compliance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% bolt-on installation:\u003c\/strong\u003e No drilling, cutting, welding, or driveshaft modification required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLifetime spring guarantee:\u003c\/strong\u003e Springs carry a lifetime guarantee against sag or 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\u003e2011–2016 Ford F-250 \/ F-350 Super Duty 4WD Diesel, single rear wheel models only\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift\u003c\/td\u003e\n      \u003ctd\u003e2.5 inches over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lift (F-250)\u003c\/td\u003e\n      \u003ctd\u003eApproximately 0.5 inches over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lift (F-350)\u003c\/td\u003e\n      \u003ctd\u003eApproximately 0.5 inches below stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shocks\u003c\/td\u003e\n      \u003ctd\u003eICON 2.0 Aluminum Series internal reservoir, qty 2, part 66512\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shocks\u003c\/td\u003e\n      \u003ctd\u003eICON 2.0 Aluminum Series internal reservoir, qty 2, part 36508\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Spring Kit\u003c\/td\u003e\n      \u003ctd\u003eDual rate coil spring kit, qty 1, part 62510\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Components\u003c\/td\u003e\n      \u003ctd\u003eLeaf spring expansion packs (qty 2, part 168507), 12\" U-bolt kit (part 67004), 1\" cast block kit (part 191201), 2\" rear bump stop spacer kit (part 61002)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eAlignment Cams\u003c\/td\u003e\n      \u003ctd\u003eIncluded; application-specific for caster correction\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOEM Wheel Fitment\u003c\/td\u003e\n      \u003ctd\u003eYes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Wheels\u003c\/td\u003e\n      \u003ctd\u003eICON Alloys 17x8.5\" (5.00\" backspace \/ 6mm offset); 18x9\" (5.25\" backspace \/ 6mm offset); 20x9\" (5.25\" backspace \/ 6mm offset)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Tires\u003c\/td\u003e\n      \u003ctd\u003e35x12.50\" (larger tires may fit but require fender trimming)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e272 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK62581\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 2011–2016 Ford F-250 or F-350 Super Duty 4WD Diesel trucks with single rear wheels who want a bolt-on 2.5-inch front lift that preserves towing capacity and improves ride quality on rough terrain and highway alike.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis system does not fit F-250 or F-350 gas engine models, dual rear wheel configurations, F-350 Cab and Chassis models, or any Ford Super Duty outside the 2011–2016 model years.
