The system ships as a matched set of twelve component assemblies and replaces the factory front coil and rear leaf arrangement with a fully adjustable, rebuildable coilover platform.\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 Compromise\u003c\/h2\u003e\n\u003cp\u003eThe front coilovers bolt directly into the OEM coil bucket location (no cutting or custom fabrication required) and allow on-vehicle ride height adjustment across the full lift range. That adjustability matters in practice: a truck used for towing one week and trail running the next can be tuned for each role without pulling the suspension apart. All front and rear shocks in this system use ICON's Continuous Damping Control Valve (CDCV) technology, giving 10 distinct compression settings from soft to firm that can be changed on the vehicle.\u003c\/p\u003e\n\n\u003ch2\u003eRadius Arms Built Around 37-Inch Tires\u003c\/h2\u003e\n\u003cp\u003eThe fabricated, fully boxed radius arms replace the factory links and are profiled specifically for tire clearance at full steering lock, allowing a 37-inch tall tire to clear without contacting the arm. A sealed pivot bushing reduces road noise and is designed for long service life. On-vehicle caster adjustment is built into the radius arm system, so alignment can be corrected after the lift without separate eccentric bolts or cam kits.\u003c\/p\u003e\n\n\u003ch2\u003eRear Compliance and Reduced Axle Wrap\u003c\/h2\u003e\n\u003cp\u003eThe rear of the system pairs 2.5 Aluminum Series CDCV piggyback reservoir shocks with leaf spring expansion packs, 1-inch cast blocks, and 12-inch U-bolts. The expansion packs add compliance to the factory leaf stack and reduce axle wrap under acceleration, a meaningful benefit on a truck that sees loaded towing or off-camber terrain. On F-250 models the blocks add approximately 0.5 inches of rear lift over stock; on F-350 models the same blocks lower rear ride height by approximately 0.5 inches compared to stock.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt-in front coilovers:\u003c\/strong\u003e fit OEM coil bucket location; coil centering cup removal required before installation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCDCV shock technology:\u003c\/strong\u003e front coilovers, front secondary shocks, and rear shocks all carry 10-setting compression damping adjustment\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual 2.0 Aluminum Series steering stabilizer kit:\u003c\/strong\u003e paired opposing stabilizers for smooth steering control\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOn-vehicle adjustable track bar:\u003c\/strong\u003e corrects axle placement after lift; bump steer bracket (part 64039) separately recommended\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eICON-engineered coil and leaf springs:\u003c\/strong\u003e guaranteed against sagging or breakage; FK Rod End bearings throughout\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully rebuildable and revalveable shocks:\u003c\/strong\u003e corrosion-resistant CAD-plated coilover bodies with 7\/8-inch shafts; aluminum-cylinder secondary and rear shocks\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\u003eItem\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\u003eK63205RL\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFitment\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\u003eFront lift range (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 range (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 range (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 range (gas, Tremor)\u003c\/td\u003e\n      \u003ctd\u003e2–2.5\" over stock\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\u003eFront shock series\u003c\/td\u003e\n      \u003ctd\u003eICON 2.5 VS Remote Reservoir CDCV (coilover) + 2.5 Aluminum Series CDCV (secondary)\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 CDCV Piggyback Reservoir\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSteering stabilizers\u003c\/td\u003e\n      \u003ctd\u003eDual ICON 2.0 Aluminum Series (opposing)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCoilover shaft diameter\u003c\/td\u003e\n      \u003ctd\u003e7\/8\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear block height\u003c\/td\u003e\n      \u003ctd\u003e1\" cast\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear U-bolt length\u003c\/td\u003e\n      \u003ctd\u003e12\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended OE tire fitment\u003c\/td\u003e\n      \u003ctd\u003e35\" x 12.50\" (37\" x 12.50\" may fit; fender trimming and modifications required)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping weight\u003c\/td\u003e\n      \u003ctd\u003e441 lb\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 2023–2026 Ford F-250 and F-350 Super Duty 4WD owners (single rear wheel configuration only) who want a complete, matched front-and-rear suspension upgrade with adjustable ride height, on-vehicle damping tuning, and fitment for tires up to 35 inches without modification.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis system does not fit F-350 Cab \u0026amp; Chassis models, dual rear wheel Super Duty trucks, or two-wheel-drive variants.
