Icon Vehicle Dynamics K64535 Stage 5 Suspension Lift Kit Lift 4.5" Ford F-250/F-350 23-26

ICON Vehicle Dynamics 4.5" Stage 5 Suspension System

The ICON Vehicle Dynamics 4.5" Stage 5 suspension system lifts 4WD 2023–2025 Ford F-250 / F-350 Super Duty trucks while improving ride quality, towing capability, and off-road performance. It combines dual-rate lift coils, fabricated geometry-correcting brackets, adjustable track bar components, and high-performance remote-reservoir shocks for a balanced on-road comfort and rugged off-road response.

The system includes engineered coil springs that provide a compliant initial rate with a firmer secondary rate for bottoming resistance, fabricated radius arm and track bar drop brackets to correct suspension geometry and reduce bump steer, and ICON 2.5 Aluminum Series CDCV remote-reservoir shocks tuned for this application. The Centerline steering stabilizer with a piggyback reservoir improves steering damping for larger tires. Heavy-duty rear blocks, stainless braided front brake lines, bump stop spacers, and extended brake lines are included for durability and safety under load.
