Icon Vehicle Dynamics K64536 Stage 6 Suspension Lift Kit Lift 4.5" Ford F-250/F-350 23-26

ICON Vehicle Dynamics 4.5" Stage 6 Suspension System (2023–2025 Ford F-250 / F-350 4WD Gas)

This 4.5" Stage 6 suspension system lifts 4WD Ford Super Duty trucks while improving ride quality, towing performance, and off-road capability. The kit is engineered as a complete system — springs, 4-link, track bar components, shocks, steering stabilizers, and hardware — to provide better articulation, reduced bump steer, and improved steering feedback with larger tires.

The system features ICON dual-rate 4.5" front coil springs for a compliant on-road ride and firm secondary rate for bottoming resistance off-road. The ICON 4-Link kit eliminates binding from factory radius arms and maintains positive caster through travel. Remote-reservoir ICON Aluminum Series shocks are vehicle-spec tuned for consistent damping and heat dissipation under extended heavy use. Included hardware and brackets center the axle, prevent sway bar bind, and provide upgraded brake lines and bump stop spacers for a complete installation.
