Premium Stage 1 Suspension System by ICON
Elevate your 2021-2026 Ford F-150 4WD to new heights with the ICON 3.5-4.5″ Stage 1 Suspension System, featuring innovative engineering and cutting-edge technology designed to enhance your off-road experience. The heart of this system lies in the high-strength ductile iron steering knuckles, meticulously crafted to replicate the suspension geometry of the formidable F-150 Tremor, effectively converting your F-150 into a Tremor powerhouse. A key highlight of this system is the adjustable coilovers, which offer an impressive 3.5-4.5″ of front lift height over stock, allowing you to accommodate larger, more aggressive wheel and tire combinations. Paired with ICON-engineered coil springs, these coilovers provide exceptional cooling properties with their internal reservoir design. The result is a remarkable 20% increase in front wheel travel without any compromise in towing capacity, all while delivering an improved ride quality over stock.
ICON Billet UCAs with Delta Joint Pro
Billet Upper Control Arms (UCAs) with Delta Joint Pro ball joints are at the core of this system. These UCAs offer added strength, durability, and on-vehicle adjustability while maintaining alignment spec range, making them the perfect companion for the extra lift height. On-vehicle caster and camber adjustment is a breeze, ensuring that your F-150 handles exceptionally well both on and off-road. The upper control arms in this system feature ICON’s patented Delta Joint PRO, an innovative suspension articulation joint that combines the best of both worlds – the longevity of factory-style ball joints with the strength and performance of motorsports-style joints. The Delta Joint PRO offers improved articulation with 90 degrees of movement, a 14% improvement over the original Delta Joint, ensuring maximum bind-free suspension movement through the entire range of travel. The durable chromoly ball and shaft are built to withstand the toughest conditions, and the lubrication system is designed for efficient grease distribution.
High-Quality Construction & Design
The ICON Stage 1 Suspension System is a 100% bolt-on solution, requiring no drilling, cutting, or welding during installation. To further enhance your driving experience, ICON equips this suspension system with vehicle-specific tuned front and rear shocks that provide superior damping and precise vehicle control. The corrosion-resistant CAD plated coilover shock bodies with 7/8″ shafts ensure long-lasting performance, and FK rod end bearings contribute to extended longevity and minimal deflection. The rear of the system features 2.0 Aluminum Series internal reservoir shocks with 5/8″ hardened chromed steel shafts, striking the perfect balance of performance for your truck. ICON’s commitment to quality is evident through their use of 6061 aircraft-grade aluminum CNC machined components throughout the system. With the ICON Stage 1 Suspension System, you’re not just upgrading your F-150; you’re enhancing its capabilities on and off the road.Vehicle Fitment: 2021, 2022, 2023, 2024, 2025, 2026 Ford F-150 4WD Wheel and Tire Fitment:
