Icon Vehicle Dynamics K64531 Stage 1 Suspension Lift Kit Lift 4.5" Ford F-250/F-350 23-26

ICON Vehicle Dynamics

This 4.5" Stage 1 suspension system is designed for 2023–2025 Ford F-250 / F-350 4WD gasoline models. It provides a front lift while improving ride quality, handling, and the ability to fit larger, more aggressive wheel and tire combinations. The system is ideal for on-road driving, towing, and mild off-road use.

• 4.5" front lift via ICON engineered dual-rate coil springs — softer initial rate for on-road comfort and a firmer secondary rate for bottoming resistance and off-road performance.
• ICON 2.0 Aluminum Series internal reservoir shocks with vehicle-specific tune for improved handling and ride quality; corrosion-resistant anodized bodies with 5/8" shafts.
• Fabricated radius arm drop brackets to correct suspension geometry and maintain proper caster and alignment.
• Track bar drop bracket to center the axle under the frame and reduce bump steer and road feedback.
• Heavy-duty rear lift blocks and U-bolt kit to raise the rear approximately 2" and withstand towing/hauling and off-road stresses.
• Includes fabricated front sway bar drop brackets, heavy-duty aluminum bump stop spacers, and extended stainless steel braided front brake lines.
• High-quality fabrication: CNC-machined, laser-cut, and brake-formed components, tested and tuned as a complete system.
• Shocks are fully rebuildable and re-tunable.
• Approximately 50% increased front wheel travel over stock for improved articulation and control.
• Lifetime coverage against coil spring breakage or sagging and against fabricated component breakage or manufacturer defect.
