Transform How Your Super Duty Handles The Road

If you’re ready to give your Super Duty the ride and control it deserves, the ICON Stage 6 2.5" Suspension System with 4-Link and Expansion Packs is built to impress from every angle. This system doesn’t just lift your 2023-2025 Ford F-250 or F-350, it completely changes how it feels behind the wheel. The 4-Link setup replaces the factory radius arms, freeing up the front end for better articulation and a smoother ride across uneven ground. Whether you’re towing heavy loads, navigating rough job sites, or exploring trails on the weekend, the system’s intelligent damping technology automatically adjusts to the terrain so you can focus on driving. The dual-rate coil springs and CDEV-equipped shocks work together to deliver exceptional comfort and stability, even when the truck is under stress. You’ll also enjoy reduced axle wrap and a more compliant rear suspension thanks to the leaf spring expansion packs. From work to play, this is a setup that gives your truck both the stance and performance to handle anything in its path.

Engineered For Precision Control And Lasting Strength

The ICON K65918L Stage 6 Suspension System combines advanced engineering with premium materials to create a balanced, high-performance upgrade for the modern Super Duty. Its 4-Link design eliminates the binding found in factory radius arm setups, allowing smoother suspension movement and consistent caster angles throughout travel. Up front, dual-rate coil springs are specifically tuned for diesel-powered trucks, improving ride quality while maintaining load capacity. The CDEV remote reservoir shocks continuously adapt damping levels using real-time feedback from the ICON Intelligent Control system, which you can fine-tune wirelessly through a smartphone app. Rear expansion packs, blocks, and U-bolts are included to improve ride compliance and minimize axle wrap for better traction and comfort. A heavy-duty adjustable track bar and bump steer correction bracket maintain precise steering geometry, while the Centerline stabilizer enhances control over rough or uneven terrain. Every shock body is crafted from corrosion-resistant anodized aluminum and built to be fully rebuildable, making this suspension system as durable as it is refined.
