Part Number: K63143

Summary: The ICON Stage 3 Coilover Conversion System provides a significant performance upgrade for 2017–2023 Ford F-250/F-350 Super Duty 4WD trucks, offering a lift range of 2.5-3 inches depending on the specific model year. This system replaces the factory coil spring with a 2.5 VS Series Remote Reservoir bolt-in coilover, allowing for user-defined ride height adjustment and superior damping. The Stage 3 system is specifically valved for diesel engines and features 2.5 Aluminum Series piggyback rear shocks for consistent fade-free performance during heavy use.

Features

• Coilover Conversion: 2.5 VS Series Remote Reservoir coilovers provide user-defined ride height adjustment and increased damping ability to ensure superior control on and off-road.
• Remote Reservoir Design: External reservoirs provide increased oil capacity and cooling surface area to ensure consistent damping performance during extended use.
• FK Rod End Bearings: PTFE-lined FK Rod End bearings provide minimal deflection and extended longevity to ensure precise suspension cycling.
• System Durability: CAD plated shock bodies with 7/8 inches shafts and anodized impact-extruded aluminum rear bodies provide maximum corrosion resistance to ensure long-term reliability in harsh environments.
• Installation: A 100% bolt-in design fits directly into OE coil bucket locations to ensure a straightforward installation without major structural modification.
