Springs in this system are rated for diesel engines only. The system ships in multiple boxes and includes all components listed below.\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\u003eHeight Adjustability Without Sacrificing Ride Quality\u003c\/h2\u003e\n\u003cp\u003eThe 2.5 VS RR CDCV bolt-in coilover conversion mounts in the factory coil bucket location, so no cutting or major fabrication is required during installation. Ride height can be dialed anywhere in the 4–5.5 inch lift window after the truck is built, letting the owner fine-tune stance for load, terrain, or tire size without pulling the suspension apart. Vehicle-specific shock valving is calibrated for the F-250\/F-350 platform, and all shocks are fully rebuildable and revalveable for long-term serviceability.\u003c\/p\u003e\n\n\u003ch2\u003eRadius Arm System Built for Clearance and Caster Control\u003c\/h2\u003e\n\u003cp\u003eThe fabricated, fully boxed radius arms use a sealed pivot bushing to minimize road feedback and reduce noise over the life of the system. The arm profile is optimized for tire clearance at full steering lock, allowing a 37-inch tall tire to clear without contacting the radius arm. Drop brackets provide on-vehicle caster adjustment, which is important when correcting geometry after a significant lift. The adjustable track bar with FK rod end bearing further refines front-end geometry and reduces deflection under load.\u003c\/p\u003e\n\n\u003ch2\u003eComponent List\u003c\/h2\u003e\n\u003cp\u003eThis Stage 5 system includes: front 4.5-inch box kit (64050); 4–5.5-inch 2.5 VS RR CDCV bolt-in coilover conversion kit (61721C); adjustable track bar with FK rod end (64035); radius arm system (64041); radius arm drop kit (64040); dual stabilizer kit (65000); dual opposing 2.0 VS IR stabilizers, qty 2 (36511); 5-inch rear block kit (195275); rear 17-inch U-bolt kit (37002); and rear 2.5 VS PB CDCV pair (37701CP).\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEibach coil springs:\u003c\/strong\u003e guaranteed for life against sagging or breakage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorrosion-resistant shock body:\u003c\/strong\u003e CAD-plated coilover body with 7\/8-inch shaft; rear shocks use one-piece impact-extruded aluminum cylinders\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFK rod end bearings:\u003c\/strong\u003e extended longevity and minimal deflection on the adjustable track bar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully rebuildable shocks:\u003c\/strong\u003e all shocks are rebuildable and revalveable for long-term use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoilover conversion:\u003c\/strong\u003e allows addition of a secondary shock (options available separately)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt-in front fitment:\u003c\/strong\u003e mounts in 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\u003eFitment\u003c\/td\u003e\n      \u003ctd\u003e2008–2010 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 over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shock Diameter\u003c\/td\u003e\n      \u003ctd\u003e2.5 inches (coilover conversion)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shock Type\u003c\/td\u003e\n      \u003ctd\u003e2.5 VS PB CDCV (pair included)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eStabilizers\u003c\/td\u003e\n      \u003ctd\u003e2.0 VS IR dual opposing (qty 2)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Block\u003c\/td\u003e\n      \u003ctd\u003e5-inch block kit\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpring Rating\u003c\/td\u003e\n      \u003ctd\u003eDiesel engines only\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOEM Wheel\/Tire Fitment\u003c\/td\u003e\n      \u003ctd\u003eYes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Tire\u003c\/td\u003e\n      \u003ctd\u003e35 x 12.50 inches (larger requires fender trimming)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK63125R\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e297 lb (ships in multiple boxes)\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 2008–2010 Ford F-250 and F-350 4WD owners running diesel engines who want 4–5.5 inches of adjustable lift, improved front and rear ride dynamics, and the ability to run up to a 35-inch tire without fender modification.

It does not fit 2WD models or model years outside 2008–2010. A carrier bearing drop bracket kit (part 33700) may be required and is sold separately. Tires larger than 35 x 12.50 inches may fit but will 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 a gas-engine F-250 or F-350?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The coil springs in this Stage 5 coilover conversion are rated for diesel engines only. A gas-engine F-250 or F-350 requires a different spring specification; this system should not be used on gas-powered trucks.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat lift height does this system provide?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThis Stage 5 coilover conversion provides 4–5.5 inches of lift over stock on a stock-equipped 2008–2010 Ford F-250 or F-350 4WD. The coilover allows end-user ride height adjustment anywhere within that range after installation.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eIs a carrier bearing drop bracket included?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eA carrier bearing drop bracket kit (part 33700) may be required for this Stage 5 coilover conversion but is not included in the system.

The recommended aftermarket tire size is 35 x 12.50 inches without fender modification; larger tires may fit but will require fender trimming and additional modifications.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eAre the shocks rebuildable?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. All shocks included in this Stage 5 coilover conversion are fully rebuildable and revalveable, supporting long-term serviceability and the ability to retune damping as the truck's use or tire load changes over time.\u003c\/p\u003e","brand":"ICON Vehicle Dynamics","offers":[{"title":"Default Title","offer_id":50631239565382,"sku":"K63125R","price":8359.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2203\/1686\/files\/f04bf1fc342e0ce39972a5464c98dfb2-sq.jpg?v=1791964873","url":"https:\/\/terrainvault.com\/products\/icon-stage-5-coilover-conversion-with-radius-arm-for-2008-2010-ford-f","provider":"TerrainVault","version":"1.0","type":"link"}
