ICON 2023-2025 Ford F-250/F-350 Super Duty 4WD 2.5-3" Lift Stage 6 Coilover Conversion System with 4-Link & Expansion Packs (K63206L)
The ICON Vehicle Dynamics Stage 6 Coilover Conversion System for the 2023–2025 Ford F-250/F-350 Super Duty is a top-tier suspension upgrade engineered for maximum articulation, precise damping control, and superior ride quality. Built around ICON’s 2.5 Series remote reservoir coilovers with CDCV adjustability, this system includes a full 4-link conversion and expansion packs to eliminate suspension bind, improve geometry, and deliver unmatched performance both on and off-road. This is a complete, race-inspired solution for serious off-road enthusiasts and heavy-duty truck owners.
Adjustable 2.5–3” Lift for Optimized Performance
This system provides adjustable front lift from 2.5 to 3 inches, allowing you to fine-tune ride height for improved ground clearance, larger tire fitment, and optimized suspension geometry. The adjustability ensures ideal performance for both daily driving and aggressive off-road use.
2.5 Series Remote Reservoir Coilovers with CDCV
ICON’s 2.5 Series coilovers feature remote reservoirs for increased oil capacity and improved heat dissipation, ensuring consistent damping under extreme conditions. The CDCV (Compression Damping Control Valve) provides 10 levels of external compression adjustment, allowing you to dial in ride quality for towing, highway driving, or off-road terrain.
4-Link Conversion for Maximum Articulation
The included 4-link conversion replaces the factory radius arm system, eliminating suspension bind and maintaining proper caster throughout the suspension cycle. This results in dramatically improved articulation, smoother ride quality, and increased control in demanding off-road environments.
Expansion Packs for Complete Suspension Enhancement
This Stage 6 system includes ICON expansion pack components such as billet rear links, adjustable track bars, and additional hardware designed to further improve axle control, suspension geometry, and overall system performance. These upgrades ensure the suspension operates as a fully integrated system.
Dual-Rate Coil Springs for Balanced Ride Quality
ICON-engineered dual-rate coil springs provide a soft initial ride for comfort and a firmer secondary rate for bottom-out resistance. This design enhances both daily drivability and off-road capability while maintaining excellent load-handling performance.
Precision Geometry and Steering Correction
An adjustable front track bar is included to properly center the axle after lifting, while additional components ensure correct steering and suspension geometry. This results in improved handling, reduced wear, and long-term durability.
Engineered for Extreme Durability
Constructed from CNC-machined 6061 aluminum and premium materials, this system is built to withstand the harshest conditions. ICON shocks are fully rebuildable and revalvable, providing long-term serviceability and consistent performance.
Complete Bolt-On High-Performance System
This Stage 6 kit is a comprehensive bolt-on upgrade that transforms your Super Duty into a high-performance off-road machine without requiring major modifications. It is ideal for overlanding, towing, and high-speed off-road driving.
