Icon Vehicle Dynamics K64553R Stage 4 Suspension Lift Kit Lift 4.5" Ford F-250/F-350 08-10

ICON Stage 4 4.5" System for 2008–2010 Super Duty

This 4.5" Stage 4 suspension system is engineered with high-quality materials and components to deliver improved ride performance and durability. It combines dual-rate front coil springs with ICON 2.5 Aluminum Series CDCV shocks and includes front coils, shocks, radius arm drop-down brackets, rear blocks and U-bolts, a patented adjustable track bar, and a 4-link kit for advanced shock and suspension control.

The ICON Vehicle Dynamics Ford Super Duty Radius Arm System features a sealed pivot bushing to minimize road feedback and ensure long life and quiet operation. The fabricated, fully boxed design provides strength and a profile optimized for tire clearance at full steering lock, allowing up to a 37" tall tire to clear the radius arm without contact.
