Part Number: K63121

Summary: The ICON Stage 1 Coilover Conversion System provides a height-adjustable suspension solution for the 2008–2010 Ford Super Duty F-250 and F-350 4WD. This system delivers a versatile 4-5.5 inches lift range, replacing the factory coil spring with a high-performance 2.5 Series Remote Reservoir coilover for superior damping. Engineered specifically for diesel applications, this system significantly improves on-road ride quality and off-road control while allowing for future expansion with secondary shocks.

Features

• Coilover Conversion: 2.5 Series Remote Reservoir coilovers provide 4-5.5 inches of adjustable ride height to ensure a level stance and improved damping performance.
• Enhanced Geometry: Radius arm drop brackets and an adjustable track bar with FK Rod Ends provide optimized axle positioning to ensure precise handling and reduced body roll.
• Premium Spring Technology: Eibach coil springs provide a lifetime guarantee against sagging to ensure consistent ride height and performance.
• System Durability: CAD plated shock bodies with 7/8 inches shafts provide maximum corrosion resistance to ensure longevity in harsh environments.
• Installation: A bolt-in design that fits into the OE coil bucket location (with removal of factory centering cup) provides a streamlined upgrade path to ensure a secure fitment.
