Tuned Suspension Technology That Responds As You Drive

The ICON K64548L Stage 8 Suspension System with Expansion Packs is engineered for 2023-2025 Ford Super Duty diesel 4WD trucks, delivering a refined ride and serious trail capability. At the core of this system are ICON’s CDEV-equipped 2.5 aluminum shocks, which actively adjust compression settings based on G-force and vehicle movement using the IIC module. This gives you smooth highway handling and fast off-road response without needing to leave the cab. Dual rate coil springs provide 4.5 inches of lift in the front while maintaining control and comfort over changing terrain. In the rear, ICON’s leaf spring expansion packs add 2 inches of lift while softening unloaded ride characteristics compared to block-only setups. The 4-link front suspension improves articulation and holds caster through the full range of travel, enhancing stability under load and during off-road flex. A dropped track bar bracket, adjustable track bar, and piggyback steering stabilizer are also included to fine-tune geometry and steering response. Built with hard anodized shock bodies and stainless brake lines, this system is ready for years of hard use.
