The system is designed for on-road daily use, towing, job-site duty, and light off-road driving. OEM wheels and tires are compatible; a single rear wheel configuration is required.\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\u003eAdjustable Ride Height Without Sacrificing Daily Drivability\u003c\/h2\u003e\n\u003cp\u003eThe 2.5 VS Series remote reservoir coilovers allow user-defined ride height adjustment within the stated lift range, so the truck can be dialed in for load, tire size, or terrain without swapping springs. Vehicle-specific valving and ICON-engineered coil springs are tuned as a matched set, which means the front end responds consistently whether the truck is empty on the highway or loaded for a job site. The coilover conversion also opens the door to adding a secondary shock in the future. Contact ICON for compatible options.\u003c\/p\u003e\n\n\u003ch2\u003eRadius Arms Built Around Tire Clearance and Caster Control\u003c\/h2\u003e\n\u003cp\u003eThe fabricated, fully boxed radius arms included in this system allow on-vehicle caster adjustment and are profiled specifically to clear a 37\" tall tire at full steering lock without contact. A sealed pivot bushing reduces road noise and is designed for long service life. Note that 37\" tires may require fender trimming and modifications; 35\" x 12.50\" tires are the recommended fitment without body modifications.\u003c\/p\u003e\n\n\u003ch2\u003eRear Suspension Compliance Through Leaf Spring Expansion Packs\u003c\/h2\u003e\n\u003cp\u003eThe rear of the system uses ICON's leaf spring expansion packs with blocks and U-bolts to reduce axle wrap and improve compliance over rough surfaces. On F-250 models, the included 1\" cast block adds approximately 0.5\" of rear lift over stock; on F-350 models, rear ride height is reduced by approximately 0.5\" compared to stock. The 2.0 Aluminum Series internal reservoir rear shocks and 2\" bump stop spacer kit complete the rear package.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.5 VS Series Remote Reservoir Coilovers:\u003c\/strong\u003e adjustable ride height, FK Rod End bearings, vehicle-specific valving, CAD-plated shock bodies with 7\/8\" shafts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFabricated Radius Arms:\u003c\/strong\u003e fully boxed design, sealed pivot bushing, on-vehicle caster adjustment, optimized for 37\" tire clearance at steering lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2.0 Aluminum Series Rear Shocks:\u003c\/strong\u003e internal reservoir, 5\/8\" shafts, fully rebuildable and revalveable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Spring Expansion Packs:\u003c\/strong\u003e blocks and U-bolts included, reduces axle wrap and improves rear compliance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eICON-Engineered Springs:\u003c\/strong\u003e coil and leaf springs guaranteed for life against sagging or breakage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt-In Front Installation:\u003c\/strong\u003e fits OE coil bucket location (coil centering cup removal 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\u003eK63201RL\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 Super Duty 4WD (single rear wheel only; excludes Cab \u0026amp; Chassis)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift, Diesel, No Tremor\u003c\/td\u003e\n      \u003ctd\u003e2.5–3\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift, Diesel, Tremor\u003c\/td\u003e\n      \u003ctd\u003e1.5–2\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift, Gas, No Tremor\u003c\/td\u003e\n      \u003ctd\u003e3–3.5\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift, Gas, Tremor\u003c\/td\u003e\n      \u003ctd\u003e2–2.5\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shock Diameter\u003c\/td\u003e\n      \u003ctd\u003e2.5\" (remote reservoir)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shaft Diameter\u003c\/td\u003e\n      \u003ctd\u003e7\/8\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shock Diameter\u003c\/td\u003e\n      \u003ctd\u003e2.0\" (internal reservoir)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shaft Diameter\u003c\/td\u003e\n      \u003ctd\u003e5\/8\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lift (F-250)\u003c\/td\u003e\n      \u003ctd\u003e+0.5\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lift (F-350)\u003c\/td\u003e\n      \u003ctd\u003e-0.5\" vs. stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Tire Size\u003c\/td\u003e\n      \u003ctd\u003e35\" x 12.50\" (37\" x 12.50\" may fit with fender trimming)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e351 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSystem Components\u003c\/td\u003e\n      \u003ctd\u003eFront coilover conversion kit (61723), radius arm system (64043), rear shocks ×2 (66516), leaf spring expansion packs ×2 (168507), U-bolt kit (67004), 1\" cast block kit (191201), rear bump stop spacer kit (61002)\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 2023–2026 Ford F-250 or F-350 Super Duty 4WD trucks (single rear wheel) who want a complete front coilover conversion with matching rear hardware for improved ride quality on-road, while towing, or on light off-road terrain.

Tremor-equipped trucks achieve a reduced front lift range; diesel Tremor models see 1.5–2\" and gas Tremor models see 2–2.5\" of front lift rather than the nominal 2.5–3\" figure. Trucks equipped with OnBoard Scales require an additional sensor bracket (part 66203); trucks with Dynamic Bending Headlamps or OnBoard Scales also require part 611081. ADAS recalibration is required after installation. An adjustable track bar (sold separately) is recommended to correct axle placement and bump steer geometry.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes this system fit my F-350 dually?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe ICON Stage 1 Coilover Conversion System (K63201RL) fits single rear wheel F-250 and F-350 Super Duty 4WD models only.
