Take Your Super Duty From Stock To Serious

If you're ready to unlock the full potential of your 2023-2025 Ford F-250 or F-350 Super Duty 4WD, the ICON Stage 6 Suspension System is built to deliver. This kit doesn’t just lift your truck 2.5 inches, it transforms how it handles both on the pavement and in the dirt. Whether you're hauling a heavy trailer, working job sites, or heading off-road for the weekend, this system is designed to handle it all with confidence. The remote reservoir shocks equipped with CDEV tech constantly adapt to the terrain, giving you a smoother, more controlled ride without needing to mess with settings mid-drive. Plus, the ICON Intelligent Control app puts the power of fine-tuning right in your hands, literally. You’ll also gain clearance for up to 37-inch tires without rubbing at full steering lock, thanks to high-clearance, boxed radius arms. From the moment you bolt this kit on, you’ll feel the difference every time you turn the wheel, hit a bump, or load up the bed. It's not just a lift, it's a serious upgrade for how your Super Duty performs in the real world.

Engineered To Handle Whatever You Throw At It

The ICON K65918RL Stage 6 system brings together precision-engineered components to create a suspension that performs as a complete, well-balanced package. Dual-rate coil springs up front are specifically tuned for diesel-powered trucks, providing improved compliance and wheel travel without compromising control under load. The 2.5 Series CDEV shocks use electronic valves to respond to changing terrain in real time, actively adjusting damping forces based on vehicle movement, G-forces, and driver-defined settings. At the rear, leaf spring expansion packs paired with cast blocks and U-bolts help reduce axle wrap and smooth out rougher roads. A heavy-duty adjustable track bar and drop bracket help correct geometry and reduce bump steer after lifting, improving overall steering response. The fully boxed radius arms come with sealed pivot bushings that reduce road feedback while still allowing for on-vehicle caster adjustment. From the shock bodies to the rod ends, every component is built for durability, longevity, and serviceability, making this one of the most advanced suspension systems available for the modern Super Duty platform.
