Upgrade your 2011–2016 Ford F-250 or F-350 handling and ride authority with the ICON K63191 Stage 1 Coilover Conversion System featuring 2.5–3 inch lift height and integrated Expansion Packs.

Replace deteriorating factory coils and shocks with the ICON K63191, a purpose-built suspension upgrade engineered specifically for the 2011 through 2016 Ford F-250 and F-350. This complete coilover conversion system delivers adjustable lift capabilities between 2.5 and 3 inches while transforming the front end into a high-performance monotube setup. By incorporating ICON's signature Expansion Packs, the kit increases internal fluid capacity and damping surface area, ensuring consistent performance whether you are navigating steep trails, managing heavy cargo, or maintaining daily drivability.

• Adjustable 2.5–3 Inch Lift Range: Thread-adjustable upper perches allow independent tuning of ride height, preload, and corner leveling to achieve up to 3 inches of lift above stock without altering the frame or requiring additional geometric modifications.
• Complete Coilover Conversion Design: Eliminates the factory coil-spring and discrete shock arrangement by bundling both functions into a single compact mono-tube assembly, simplifying installation and improving packaging efficiency within the wheel well.
• Expansion Packs for Increased Travel: Each coilover ships with an integrated Expansion Pack reservoir attachment that supplements the main body fluid volume, reducing cavitation risk and extending component longevity during aggressive driving or long-travel compression events.
• Stage 1 Performance Engineering: Built around MONOTUBE hydraulic technology principles characteristic of the Stage 1 platform, these units manage heat buildup and maintain stable阻尼 forces under heavy Super Duty loads that typically overwhelm OEM dampers.
• Vehicle-Specific Mounting Geometry: Engineered exclusively for the 2011–2016 Super Duty chassis pattern, this kit bolts directly into existing locations with no cutting or welding required, preserving proper alignment parameters when installed correctly.
• Resolved Front-End Sinkage: Addresses common factory stiffness and sag issues in loaded F-250 and F-350 models by providing progressive spring rates and refined damping that balance load support with improved ride absorption.
