Give Your Super Duty The Suspension It Deserves

If you want to take your truck from capable to unstoppable, the ICON Stage 6 Suspension System with Expansion Packs is the upgrade that makes it happen. This setup lifts the front of your Super Duty 4.5 inches and adds 2 inches of rear lift with expansion packs, giving your truck the stance and clearance for larger, more aggressive tires. The dual rate coil springs smooth out the bumps on the road but stiffen up under load, so whether you are towing a trailer or hitting uneven trails, you stay in control. The ICON 2.5 shocks with remote reservoirs are designed to handle heat and heavy use, keeping performance consistent mile after mile. Expansion packs improve rear ride quality and reduce axle wrap compared to standard block lifts, which makes a noticeable difference when hauling or off-roading. With the addition of ICON’s 4-Link system, your truck gains better articulation and stability while keeping steering geometry dialed in. Add in the dual steering stabilizers and stainless steel brake lines, and this kit not only looks the part but also delivers confidence every time you get behind the wheel.

Built For Strength Control And Consistency

The ICON K64536L Stage 6 System is engineered as a complete suspension solution for 2023–2025 F-250 and F-350 gas 4WD trucks. At the front, dual rate coil springs provide 4.5 inches of lift while balancing comfort and load support, and the 2.5 Aluminum Series shocks with remote reservoirs are tuned specifically for Super Duty applications. Remote reservoirs increase oil volume and cooling capacity, preventing shock fade during extended use or heavy off-road driving. ICON’s 4-Link system replaces the factory setup to eliminate binding during articulation, while maintaining proper caster across the suspension’s full range of travel. The adjustable track bar keeps the front axle properly centered, reducing bump steer and improving overall stability. Out back, expansion packs deliver a 2 inch lift with improved compliance and control over standard block lifts. Stainless steel braided brake lines, sway bar drop brackets, and heavy-duty bump stop spacers are included to maintain reliability under added height. With fully rebuildable shocks and a lifetime warranty on springs and fabricated parts, this system is built to last and designed to perform in any environment.
