All components are engineered and tuned as a matched system. Front lift range varies by powertrain and Tremor package; see the application notes in the Specifications table for your exact 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. We email tracking as soon as your order ships.\u003c\/p\u003e\n\n\u003ch2\u003eRide-Height Adjustability Without Compromise\u003c\/h2\u003e\n\u003cp\u003eThe 2.5 Series remote reservoir front coilovers bolt into the OEM coil bucket location and allow end-user ride-height adjustment across the rated lift range, so the truck can be dialed in after installation rather than locked to a fixed height. Remote reservoirs increase shock oil volume and heat-dissipation surface area, resisting the cavitation and damper fade that occur under sustained hard use on washboard roads or loaded towing runs. Coilover bodies are CAD-plated with 7\/8\" shafts for corrosion resistance, and shocks are fully rebuildable and re-tunable. The coilovers also accept secondary shocks in the stock location (effectively doubling damping capacity) when that option is needed.\u003c\/p\u003e\n\n\u003ch2\u003eGeometry Correction Built Into the Kit\u003c\/h2\u003e\n\u003cp\u003eFabricated radius arm drop brackets restore proper suspension geometry and caster with the OEM radius arms, keeping wheel alignment within spec after the lift. The fabricated track bar drop bracket re-centers the axle under the frame and eliminates bump steer. An adjustable track bar replaces the deflective OEM bushings with a rigid unit that can be fine-tuned on the vehicle for track alignment. Together these three components address the geometry compromises that a lift alone introduces, rather than leaving them for a separate alignment kit.\u003c\/p\u003e\n\n\u003ch2\u003eSteering and Rear Lift Matched to the Front\u003c\/h2\u003e\n\u003cp\u003eA dual opposing steering stabilizer kit using ICON 2.0 Aluminum Series shocks with anodized bodies and 5\/8\" shafts controls the additional steering feedback that larger tires generate. At the rear, heavy-duty fabricated 5\" lift blocks and a 15\" U-bolt kit raise the truck to match the front lift and are built to handle towing and hauling loads as well as off-road stress. ICON 2.5 Aluminum Series piggyback reservoir rear shocks carry a vehicle-specific tune for on- and off-road ride quality. The included box kit adds fabricated front sway bar drop brackets, aluminum bump stop spacers, and stainless steel extended brake lines.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5 Series remote reservoir front coilovers:\u003c\/strong\u003e bolt-in fit in OEM coil bucket, ride-height adjustable, CAD-plated bodies, 7\/8\" shafts, fully rebuildable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGeometry-correction hardware:\u003c\/strong\u003e radius arm drop brackets, track bar drop bracket, and adjustable track bar included\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual opposing steering stabilizers:\u003c\/strong\u003e ICON 2.0 Aluminum Series shocks with anodized bodies and 5\/8\" shafts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5 Aluminum Series piggyback rear shocks:\u003c\/strong\u003e vehicle-specific tune, hard-anodized bodies, 7\/8\" shafts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e5\" fabricated rear lift blocks and 15\" U-bolt kit:\u003c\/strong\u003e rated for towing\/hauling and off-road use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox kit included:\u003c\/strong\u003e sway bar drop brackets, aluminum bump stop spacers, stainless steel extended brake lines\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\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFitment Restrictions\u003c\/td\u003e\n      \u003ctd\u003eSingle rear wheel models only;

It accommodates OEM wheels and tires and fits 37\" aftermarket tires without body modifications.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis system does not fit F-350 or F-450 Cab and Chassis models, dual rear wheel configurations, or 2WD Super Duty trucks. Trucks with the Tremor package will see a reduced lift range compared to non-Tremor models. Installation requires removal of the coil centering cup from the factory coil bucket and recalibration of Advanced Driver Assistance Systems (ADAS) after install. Tires larger than 37\" 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 system fit both F-250 and F-350 Super Duty trucks?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThis ICON Stage 4 Coilover Conversion System fits 2023–2026 Ford F-250 and F-350 Super Duty 4WD models with single rear wheels.
