The kit is compatible with factory wheels and tires and accommodates up to 37x12.50\" aftermarket tires without fender modification.\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.

When the suspension compresses further on rough terrain or under heavy load, the spring transitions to a firmer secondary rate that resists bottoming and keeps the front end composed. Buyers who run a single-rate spring typically have to choose between on-road comfort and off-road control; this kit is designed so that trade-off is not necessary.\u003c\/p\u003e\n\n\u003ch2\u003eCorrosion Resistance Built Into the Finish\u003c\/h2\u003e\n\u003cp\u003eEach spring receives a dual-stage, semi-gloss powder coat that provides a harder, more chemically resistant surface than single-stage finishes. For trucks that see road salt, mud, or regular water crossings, this matters: a spring that corrodes prematurely can lose its rated height and structural integrity before the end of its service life. The powder coat is part of why ICON backs these springs with a lifetime guarantee against sagging and breakage.\u003c\/p\u003e\n\n\u003ch2\u003eBolt-On Installation, No Cutting Required\u003c\/h2\u003e\n\u003cp\u003eThe kit is a 100% bolt-on system with no drilling, cutting, or fabrication required. An optional extended stainless brake line kit (Part #61110) is available for owners who prefer not to bend the factory steel lines or want a braided stainless upgrade, but it is not required to complete the installation.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4.5\" front lift height\u003c\/strong\u003e on non-Tremor models (3.5\" on Tremor-equipped trucks)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-rate spring design:\u003c\/strong\u003e softer initial rate for road comfort, firmer secondary rate for off-road compression resistance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-stage semi-gloss powder coat\u003c\/strong\u003e for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% bolt-on system\u003c\/strong\u003e with no cutting or fabrication required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLifetime guarantee\u003c\/strong\u003e against sagging and breakage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible with factory wheels and tires;\u003c\/strong\u003e supports up to 37x12.50\" aftermarket tires without fender modification\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\u003e64011\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2020–2022 Ford F-250 \/ F-350 Super Duty 4WD Diesel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePosition\u003c\/td\u003e\n      \u003ctd\u003eFront\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift Height\u003c\/td\u003e\n      \u003ctd\u003e4.5\" (non-Tremor) \/ 3.5\" (Tremor-equipped)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpring Design\u003c\/td\u003e\n      \u003ctd\u003eDual rate\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFinish\u003c\/td\u003e\n      \u003ctd\u003eDual-stage semi-gloss powder coat\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInstallation\u003c\/td\u003e\n      \u003ctd\u003e100% bolt-on\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e75 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Wheels\u003c\/td\u003e\n      \u003ctd\u003eICON Alloys 17x8.5\" (5\" backspace \/ 6mm offset); 18x9\" (5.25\" backspace \/ 6mm offset); 20x9\" (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\u003e37x12.50\" (larger tires may fit but require fender trimming and modifications)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOptional Accessory\u003c\/td\u003e\n      \u003ctd\u003eExtended stainless brake line kit, Part #61110 (not required for installation)\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 kit suits owners of 2020–2022 Ford F-250 or F-350 Super Duty trucks with 4WD Diesel drivetrains who want a 4.5\" front lift with improved on- and off-road ride quality, and who plan to run factory wheels or aftermarket wheels in the recommended fitments above.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis kit does not fit gas-engine Super Duty models, 2WD configurations, or model years outside 2020–2022.

Spring rates are optimized for the weight of the diesel drivetrain; gas-engine models are not a supported fitment for this kit.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eHow much lift will I get if my truck has the Tremor package?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eTremor-equipped 2020–2022 Ford F-250 and F-350 Super Duty trucks will see approximately 3.5\" of front lift height with this kit, not the standard 4.5\". The difference is due to the Tremor package's factory suspension geometry. Non-Tremor models achieve the full 4.5\" front lift.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDo I need to replace the brake lines when installing this kit?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe extended stainless brake line kit (Part #61110) is optional, not required. The ICON 64011 coil spring kit can be fully installed without it.

Larger tires may physically fit but will require fender trimming and further modifications; the extent of those modifications depends on the specific tire and wheel combination chosen.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDoes this kit include shocks or rear suspension components?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The ICON 64011 kit includes front coil springs only. Shocks, rear springs, and all other suspension components are sold separately. ICON notes that increased wheel travel from these springs is realized when used in combination with compatible ICON shocks.\u003c\/p\u003e\n\n\u003cp\u003eWARNING: This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm.\u003c\/p\u003e","brand":"ICON Vehicle Dynamics","offers":[{"title":"Default Title","offer_id":50629352980550,"sku":"64011","price":406.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2203\/1686\/files\/1a52868981be932070ca1043fbf0b6a1-sq.jpg?v=1791945897","url":"https:\/\/terrainvault.com\/products\/icon-vehicle-dynamics-2020-2022-ford-f-250-f-350-super-duty-4wd-diesel","provider":"TerrainVault","version":"1.0","type":"link"}
