Note that PowerBoost hybrid models achieve a lift range of 2.5–3.25 inches and Power-Stroke diesel models achieve 2.25–3 inches over stock.\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.

We email tracking as soon as your order ships.\u003c\/p\u003e\n\n\u003ch2\u003eMore Damping Capacity Where It Counts\u003c\/h2\u003e\n\u003cp\u003eThe 2.5-inch shock body provides greater piston area than stock front shocks, which translates directly to more consistent damping force across a wider range of terrain and speed. Whether the road surface is smooth pavement or a corrugated trail, the larger piston resists fade and maintains control in conditions that overwhelm smaller-diameter units. The internal nitrogen reservoir supports that consistency, keeping the shock fluid aerated and performing predictably under sustained hard use with no fade-out mid-run.\u003c\/p\u003e\n\n\u003ch2\u003eVehicle-Specific Valving for Street and Trail\u003c\/h2\u003e\n\u003cp\u003eICON tunes the valving for the F-150's specific weight, geometry, and suspension travel rather than applying a generic calibration. The result is a sport-tuned feel that works on paved roads without the harshness that often accompanies a lifted truck, and enough off-road compliance to handle uneven terrain confidently. FK rod end bearings at the lower mount reduce deflection and extend service life compared to rubber bushings, keeping the suspension geometry consistent over time.\u003c\/p\u003e\n\n\u003ch2\u003eLift Range That Opens Up Wheel and Tire Options\u003c\/h2\u003e\n\u003cp\u003eThe 2.75–3.5-inch adjustable lift range (on standard-engine models) creates clearance for larger wheel and tire combinations. Aftermarket wheels with lower offset and less backspace than typical OE fitments are recommended: 17x8.5-inch at 5-inch backspace\/6mm offset, 18x9-inch at 5.25-inch backspace\/6mm offset, or 20x9-inch at 5.625-inch backspace\/16mm offset. Tire size up to 34x12.50 inches is recommended; larger tires may require fender trimming or other modifications.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5-inch shock body:\u003c\/strong\u003e larger piston area than stock for improved damping capacity\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal nitrogen reservoir:\u003c\/strong\u003e maintains consistent performance under sustained hard use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable lift height:\u003c\/strong\u003e 2.75–3.5 inches over stock (standard engine); varies by powertrain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFK rod end bearings:\u003c\/strong\u003e extended longevity and minimal deflection at the lower mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e6061 aircraft-grade aluminum components:\u003c\/strong\u003e CNC machined; corrosion-resistant CAD-plated shock body with 7\/8-inch shaft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% bolt-on installation:\u003c\/strong\u003e no drilling, cutting, or welding required\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\u003e91724\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock body diameter\u003c\/td\u003e\n      \u003ctd\u003e2.5 inches\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShaft diameter\u003c\/td\u003e\n      \u003ctd\u003e7\/8 inch\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eReservoir type\u003c\/td\u003e\n      \u003ctd\u003eInternal nitrogen\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift range (standard engine)\u003c\/td\u003e\n      \u003ctd\u003e2.75–3.5 inches over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift range (PowerBoost hybrid)\u003c\/td\u003e\n      \u003ctd\u003e2.5–3.25 inches over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift range (Power-Stroke diesel)\u003c\/td\u003e\n      \u003ctd\u003e2.25–3 inches over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaterial\u003c\/td\u003e\n      \u003ctd\u003e6061 aircraft-grade aluminum; CAD-plated shock body\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eQuantity\u003c\/td\u003e\n      \u003ctd\u003ePair (2 shocks)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle fitment\u003c\/td\u003e\n      \u003ctd\u003e2021–2026 Ford F-150 4WD (standard, PowerBoost, Power-Stroke)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDoes not fit\u003c\/td\u003e\n      \u003ctd\u003eF-150 Tremor, F-150 Raptor, factory electronic suspension, 2WD models\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\"\u003eThese coilovers suit 2021–2026 Ford F-150 4WD owners who want a meaningful lift with improved front damping for mixed on-road and off-road driving, and who are prepared to install ICON Delta Joint Pro upper control arms and have their Advanced Driver Assistance Systems recalibrated after installation.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThese coilovers do not fit F-150 Tremor or F-150 Raptor models, any F-150 equipped with factory electronically controlled suspension, or 2WD F-150 variants.

On Power-Stroke diesel models, the lift range is 2.25–3 inches. Standard-engine F-150 4WD models achieve the full 2.75–3.5-inch range.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eIs ADAS recalibration required after installation?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. Installing the ICON V.S. 2.5 Series Front Coilovers on a 2021–2026 Ford F-150 requires recalibration of the vehicle's Advanced Driver Assistance Systems (ADAS) after installation.
