Turn Your Super Duty Into A True Performer

If you are ready to take your truck beyond stock limitations, the ICON Stage 6 Suspension System is built to deliver serious capability and control. This kit gives your F-250 or F-350 a 4.5 inch lift up front, giving your truck the aggressive stance and clearance needed for larger tires and tougher terrain. The dual rate coil springs provide the best of both worlds, with a smooth and comfortable ride on the street and firm stability when things get rough off-road. ICON’s 2.5 remote reservoir shocks keep their cool even under heavy use, meaning consistent performance during long days on the job site or trail. The addition of ICON’s 4-Link system ensures your truck articulates better while maintaining proper geometry, keeping steering predictable and sharp. A dual steering stabilizer kit adds confidence when running oversized tires, reducing unwanted feedback through the wheel. From towing to trail rides, this suspension system transforms your Super Duty into a truck that feels as strong and capable as it looks.

Advanced Suspension Engineering For Maximum Strength And Control

The ICON K64536 Stage 6 System combines high quality materials and thoughtful design to create a suspension package tailored to 2023–2025 gas-powered Super Duty trucks. At the core are dual rate coil springs that provide 4.5 inches of lift while balancing comfort and load resistance for a well-rounded driving experience. The 2.5 Aluminum Series shocks include remote reservoirs that increase oil volume and cooling capacity, ensuring resistance to fade during extended use. ICON’s 4-Link system is designed to reduce binding during articulation while maintaining positive caster throughout the full range of suspension travel, a key advantage when driving in demanding conditions. The adjustable track bar works with the drop bracket to center the front axle and reduce bump steer, keeping handling consistent on and off road. Stainless steel braided brake lines, sway bar drop brackets, and heavy-duty rear lift blocks are included to ensure proper function and durability under added lift. Every shock is fully rebuildable and tunable, while ICON backs their coil springs and fabricated components with a lifetime warranty. This system is engineered to provide lasting performance no matter how demanding the terrain or workload may be.
