Springs in this system are rated for diesel engines only.\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.

That adjustability matters on a work truck or expedition rig where payload, towing tongue weight, or tire size can shift the static ride height over time. The coilover design also accepts a secondary shock, giving builders a path to a bypass or piggyback setup without replacing the primary unit.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt to Last in Harsh Conditions\u003c\/h2\u003e\n\u003cp\u003eThe coilover shock body is CAD-plated for corrosion resistance and uses a 7\/8-inch shaft. Rear shocks feature one-piece impact-extruded aluminum cylinders, which resist corrosion and maintain a consistent finish across the life of the shock. FK rod end bearings on the adjustable track bar reduce deflection and extend service intervals compared to rubber bushings. Eibach coil springs carry a lifetime guarantee against sagging or breakage.\u003c\/p\u003e\n\n\u003ch2\u003eFully Serviceable, Fully Revalveable\u003c\/h2\u003e\n\u003cp\u003eEvery shock in the Stage 4 system is fully rebuildable and revalveable, so worn seals or a valving change for a heavier tire or load does not require buying a new shock. Vehicle-specific valving is set from the factory for the F-250\/F-350 platform, reducing the break-in guesswork common with universal-valved shocks.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt-in front coilover:\u003c\/strong\u003e mounts in OEM coil bucket location; coil centering cup removal required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRide height adjustable:\u003c\/strong\u003e 4–5.5 inches of lift, adjustable at the coilover collar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEibach coil springs:\u003c\/strong\u003e lifetime guarantee against sag or breakage; rated for diesel engines only\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully rebuildable shocks:\u003c\/strong\u003e all shocks are rebuildable and revalveable in the field or at a shop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFK rod end track bar:\u003c\/strong\u003e adjustable with FK rod end bearings for minimal deflection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary shock compatible:\u003c\/strong\u003e coilover conversion allows addition of a secondary shock\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\u003eFitment\u003c\/td\u003e\n      \u003ctd\u003e2005–2010 Ford F-250 \/ F-350 4WD\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift Range\u003c\/td\u003e\n      \u003ctd\u003e4–5.5 inches (ride-height adjustable)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shock Diameter\u003c\/td\u003e\n      \u003ctd\u003e2.5 inches\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCoilover Shaft Diameter\u003c\/td\u003e\n      \u003ctd\u003e7\/8 inch\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCoilover Body Finish\u003c\/td\u003e\n      \u003ctd\u003eCAD-plated\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shock Cylinder\u003c\/td\u003e\n      \u003ctd\u003eOne-piece impact-extruded aluminum\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSprings\u003c\/td\u003e\n      \u003ctd\u003eEibach; rated for diesel engines only\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOEM Wheel and Tire 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 with 5.00\" backspace \/ 6mm offset; 18x9 with 5.25\" backspace \/ 6mm offset; 20x9 with 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 and modifications)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e279 lb (ships in multiple boxes)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK63114\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eSystem Components\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eFront 4.5\" box kit (qty 1)\u003c\/li\u003e\n  \u003cli\u003e2.5 VS RR CDCV bolt-in coilover conversion kit (qty 1)\u003c\/li\u003e\n  \u003cli\u003eAdjustable track bar with FK rod end (qty 1)\u003c\/li\u003e\n  \u003cli\u003e4-link frame bracket kit (qty 1)\u003c\/li\u003e\n  \u003cli\u003eFront upper links (qty 1)\u003c\/li\u003e\n  \u003cli\u003eFront lower links (qty 1)\u003c\/li\u003e\n  \u003cli\u003e5\" block kit (qty 1)\u003c\/li\u003e\n  \u003cli\u003eRear U-bolt kit (qty 1)\u003c\/li\u003e\n  \u003cli\u003eRear 2.5 VS PB CDCV pair (qty 1)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eCalifornia Proposition 65 Warning: This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm.\u003c\/p\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThis system suits 2005–2010 Ford F-250 and F-350 4WD owners running diesel engines who want a height-adjustable lift in the 4–5.5 inch range with a fully rebuildable, performance-valved coilover front end and upgraded rear shocks.

Owners of gasoline-powered 2005–2010 F-250 or F-350 trucks should contact TerrainVault to identify the correct ICON system for their application before purchasing.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes installation require cutting or modifying the factory coil bucket?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo cutting is required, but the coil centering cup inside the factory coil bucket must be removed before the front coilover can be installed. The coilover itself bolts into the OEM coil bucket location without further modification to the bucket.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eCan I run my stock wheels and tires after installing this system?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. The ICON Stage 4 Coilover Conversion System is confirmed compatible with OEM F-250\/F-350 wheels and tires. For aftermarket fitment, ICON recommends wheels up to 20x9 at the specific backspace and offset figures listed in the Specifications table above.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eAre the shocks serviceable after installation, or do they need to be replaced as a unit?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eEvery shock in the Stage 4 system is fully rebuildable and revalveable. Worn seals can be replaced and valving can be changed without purchasing a new shock, which reduces long-term ownership cost on a high-mileage or heavily used truck.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes this system allow for a secondary shock to be added later?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. The coilover conversion in the Stage 4 system is designed to accept a secondary shock, giving owners the option to add a bypass or piggyback unit to the front end at a later date without replacing the primary coilover.\u003c\/p\u003e","brand":"ICON Vehicle Dynamics","offers":[{"title":"Default Title","offer_id":50631061438534,"sku":"K63114","price":7980.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2203\/1686\/files\/f245822dac18a38553997cc899876838-sq.jpg?v=1791964086","url":"https:\/\/terrainvault.com\/products\/icon-stage-4-coilover-conversion-system-for-2005-2010-ford-f-250-f-350","provider":"TerrainVault","version":"1.0","type":"link"}
