These springs are engineered to provide a significant increase in ride height while delivering a \"best of both worlds\" ride quality. The dual-rate design features a softer initial rate to soak up small road chatter and a firmer secondary rate that engages during deeper compression to provide excellent bottoming resistance during aggressive off-road use or heavy hauling.\u003c\/p\u003e\n\n\u003ch6\u003eFeatures\u003c\/h6\u003e\n\u003cul\u003e\n  \u003cli\u003e4.5-Inch Lift Height: Provides ample clearance for up to 37-inch tires and creates an aggressive, leveled stance.\u003c\/li\u003e\n  \u003cli\u003eDual Rate Design: Delivers superior on-road comfort without sacrificing the stability and bottoming control required for off-road performance.\u003c\/li\u003e\n  \u003cli\u003eShot-Peened \u0026amp; Pre-Set: Manufactured to the highest industry standards to prevent sagging or breakage, ensuring consistent ride height for the life of the truck.\u003c\/li\u003e\n  \u003cli\u003eIncreased Wheel Travel: Optimized to work with ICON 2.5 Series shocks to unlock maximum vertical wheel travel.\u003c\/li\u003e\n  \u003cli\u003ePremium Finish: Finished in a durable, dual-stage semi-gloss black powder coat for maximum corrosion resistance against road salts and debris.\u003c\/li\u003e\n  \u003cli\u003eLifetime Guarantee: Backed by ICON’s lifetime warranty against spring sagging or breakage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch6\u003eNotes\u003c\/h6\u003e\n\u003cul\u003e\n  \u003cli\u003eSpecifically fits 2005-2025 Ford F-250 and F-350 Super Duty 4WD models.\u003c\/li\u003e\n  \u003cli\u003e2020-2025 Models: Due to factory height changes, these springs may provide closer to 5-5.5 inches of lift on newer trucks.\u003c\/li\u003e\n  \u003cli\u003eTremor-equipped models will see approximately 3.5 inches of lift over their factory height.\u003c\/li\u003e\n  \u003cli\u003eOptimized for Diesel engine models; gas-equipped trucks will sit slightly higher than the advertised lift height.\u003c\/li\u003e\n  \u003cli\u003eRequires the use of an adjustable track bar or track bar drop bracket to ensure the front axle remains centered.\u003c\/li\u003e\n  \u003cli\u003eExtended brake lines and radius arm drop brackets or aftermarket radius arms are required at this lift height to maintain proper geometry.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ICON","offers":[{"title":"Default Title","offer_id":42991927656537,"sku":"ICO64010","price":507.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8030\/9593\/files\/4f48de6730298ec5fc978dd7f69b6cec.jpg?v=1768603199","url":"https:\/\/dirtygarage.com\/products\/icon-2005-ford-f-250-f-350-front-4-5in-dual-rate-spring-kit","provider":"Dirty Garage","version":"1.0","type":"link"}
