Dominate Every Mile With Confidence And Control

If you're looking to lift your Super Duty and actually improve how it rides and handles, the ICON Stage 6 Suspension System is the top-tier solution that delivers. This system isn’t just for show, it’s built to perform under real-world pressure, whether you're towing heavy loads, pushing through rocky terrain, or cruising to work. The 4.5 inches of front lift paired with heavy-duty 5-inch rear blocks gives your truck a powerful stance while maintaining full functionality. Where it really sets itself apart is the addition of ICON’s 4-Link system, which enhances suspension articulation and keeps caster stable through the entire travel range. The result is a smoother, more controlled ride with better traction and reduced frame bind when the terrain gets uneven. CDCV-equipped shocks offer 10 external compression settings, letting you dial in your ride for different loads or conditions with the turn of a knob. Add in the dual steering stabilizers and you get a truck that stays planted and predictable, no matter what you're hauling or where you're headed.

Full Link Suspension Geometry Tuned For Heavy Duty Use

The Stage 6 system is ICON’s most refined suspension setup for 2023-2025 diesel Super Duty trucks, featuring performance-focused components designed to work together as a complete system. At its core is the ICON 4-Link system, replacing factory radius arms with front upper and lower links to improve articulation and eliminate bind under movement. This setup also maintains proper caster angle through the full range of travel, improving steering feel and straight-line stability on and off road. Dual-rate coil springs up front balance soft ride quality with the firmness needed for loaded conditions, while rear lift is handled by 5-inch fabricated blocks built for towing and hauling. The 2.5 Aluminum Series remote reservoir shocks include ICON’s CDC Valves, allowing 10-position external adjustment for compression damping, ideal for switching between highway, worksite, and trail driving. A track bar drop bracket and adjustable track bar ensure proper axle alignment and bump steer correction. Stainless braided brake lines, aluminum bump stop spacers, and sway bar drop brackets round out a package that offers both capability and confidence with every mile.
