Icon 4-5.5″ Coilover Conversion System For 2017-2025 Ford F-250 4WD (Stage 4)

ICON 2017–2022 Ford F-250/F-350 Stage 4 4-5.5 inches Suspension System

Part Number: K63154

Summary: The ICON Stage 4 suspension system provides a high-performance coilover conversion for the 2017–2022 Ford F-250 and F-350 Super Duty. This system offers a significant upgrade in ride quality and off-road capability by replacing the factory coil springs with height-adjustable 2.5 Series coilovers, allowing for 4–5.5 inches of front lift (model year dependent). This stage is distinguished by the inclusion of a dual steering stabilizer kit and CDCV (Compression Damping Control Valve) technology for precise external tuning of your suspension’s damping characteristics.

Features

• Coilover Conversion: 2.5 Series Remote Reservoir coilovers with CDCV provide adjustable damping and ride height to ensure superior control across varied terrain.
• CDCV Technology: External Compression Damping Control Valve provides 10 distinct damping settings to ensure optimal performance for specific loads or environments.
• Radius Arm Drops: Included drop brackets correct caster geometry to ensure factory-like handling and alignment specs at increased lift heights.
• Dual Steering Stabilizers: Opposing 2.0 VS Series stabilizers provide increased steering damping to ensure reduced feedback and improved tracking with larger tires.
• System Durability: CAD-plated shock bodies with 7/8 inches shafts and Eibach coil springs provide maximum corrosion resistance to ensure a lifetime of reliable performance.
• Installation: Bolt-in design for OE coil bucket locations provides a streamlined setup to ensure a precise fitment (requires removal of factory coil centering cup).
