Experience The Ride Your Super Duty Was Missing

If you're building a 2023-2025 Super Duty that needs to handle work, play, and everything in between, the ICON Stage 8 Suspension System with Radius Arms and Expansion Packs checks every box. This isn’t just about ride height, it’s about upgrading how your truck feels behind the wheel. The 4.5" lift gives you clearance for larger tires while the leaf spring expansion packs smooth out the rear ride, especially when unloaded. On the road, it stays composed. Off the road, it stays confident. Thanks to ICON’s Intelligent Control system and CDEV shocks, your truck will react in real time to changing terrain without needing constant adjustments from the driver. You can control settings from your phone, but once it's dialed in, the system works automatically. It’s a setup designed for truck owners who want premium ride quality, tough components, and a system that performs everywhere, from job sites to backcountry trails.

Tuned Suspension With Smart Technology And Built In Strength

The ICON K65907RL Stage 8 Suspension System is engineered for diesel-powered 2023-2025 Ford F-250 and F-350 trucks, offering a refined lift solution for both on-road and off-road use. Dual rate coil springs deliver 4.5 inches of front lift while maintaining consistent control through varied terrain, and the rear expansion packs add 2 inches of lift with better ride compliance than standard lift blocks. ICON’s 2.5 Series CDEV shocks are equipped with remote reservoirs for improved heat dissipation, and they work in sync with the IIC module to actively adjust compression damping using real-time sensor input. The fabricated radius arms increase strength, improve tire clearance at full lock, and provide on-vehicle caster adjustment without the need for drop brackets. Steering geometry is refined with a dropped track bar bracket and a fully adjustable track bar, reducing bump steer and enhancing road feel. A 2.5 Centerline stabilizer with piggyback reservoir helps control larger tires and improve high-speed stability. This kit includes stainless brake lines, sway bar drop brackets, bump stop spacers, and all necessary hardware, making it a complete performance solution backed by ICON’s trusted lifetime guarantee on fabricated components.
