ICON ICON 2011–2016 Ford F-250/F-350 Super Duty 4–5.5 inches Lift Stage 3 Coilover Conversion System

Part Number: K63133

Summary: The ICON Stage 3 Coilover Conversion System provides a high-performance, height-adjustable suspension solution for the 2011–2016 Ford F-250 and F-350 Super Duty 4WD. This system transitions the factory coil spring front end to a 2.5 Series Remote Reservoir Coilover, allowing for 4–5.5 inches of lift while significantly increasing wheel travel and damping capacity. Engineered for diesel applications, this stage includes an adjustable track bar with FK Rod End bearings and radius arm drop brackets to maintain proper suspension geometry and superior on-road and off-road ride dynamics.

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 control.
• System Geometry: Radius arm drop brackets and an adjustable track bar provide corrected caster and axle alignment to ensure precise handling and steering response.
• Performance Springs: Eibach coil springs provide a lifetime guarantee against sagging to ensure consistent ride height and load support.
• System Durability: CAD plated shock bodies with 7/8 inches shafts provide superior corrosion resistance to ensure long-term reliability in harsh environments.
• Installation: Bolt-in design fits into OE coil bucket locations (with removal of factory centering cup) to provide a straightforward upgrade path for Super Duty owners.
