Ride Higher With Confidence And Real Comfort

When you’re lifting your Super Duty, you want more than just a tall stance, you want a suspension that works just as hard as your truck does. The ICON Stage 4 Coilover Conversion System with Expansion Packs gives your 2023-2025 F-250 or F-350 the clearance to run larger tires while delivering a smoother, more controlled ride in every condition. With front lift adjustability from 4 to 5.5 inches and 2 inches of rear lift from ICON’s leaf spring expansion packs, this kit gives you a balanced, functional setup built for towing, hauling, and weekend trail runs. The expansion packs ride better than standard lift blocks and help minimize axle wrap when you’re under load. You’ll feel more confident behind the wheel too, thanks to the dual steering stabilizers and an adjustable track bar that improves front-end tracking and steering response. Whether you're headed out to the job site or exploring rough terrain, this system delivers performance and comfort that factory suspension just can’t match. It bolts on cleanly, holds up to real-world abuse, and transforms how your truck handles the road ahead.

Suspension Control Tuned For Real World Duty

The Stage 4 kit with expansion packs is designed to correct suspension geometry and deliver dependable performance across varied terrain. ICON’s 2.5 Series coilovers with remote reservoirs mount directly into the factory coil buckets and provide both lift adjustability and fade-resistant performance under demanding use. In the rear, 2.5 Series piggyback reservoir shocks pair with expansion leaf packs to offer improved compliance, greater articulation, and reduced axle wrap compared to traditional lift block systems. The radius arm drop brackets maintain proper caster and suspension geometry, while the track bar drop bracket and adjustable track bar ensure the axle stays centered and bump steer is kept to a minimum. ICON includes stainless steel braided brake lines and heavy-duty U-bolts, ensuring all supporting components match the strength of the core system. The dual steering stabilizer kit features 2.0 shocks to reduce steering feedback, especially useful when running oversized tires. Every piece is engineered to work together as a system, delivering precise handling and improved ride quality on and off the road.
