Premium Stage 4 Suspension System by ICON

For the uncompromising and dedicated driver of the 2021-2024 Ford F-150 4WD, ICON introduces the epitome of suspension systems – the 3.5-4.5" Stage 4 Suspension System, meticulously engineered for supreme performance and precision, both on and off the beaten path. ICON Vehicle Dynamics' unwavering commitment to excellence shines through in this exceptional suspension system, designed to elevate wheel travel and damping ability, delivering unparalleled vehicle control and ride quality. At its core, this extraordinary system features high-strength CNC machined ductile iron steering knuckles, thoughtfully designed to replicate the suspension geometry of the formidable F-150 Tremor. These knuckles essentially transform your F-150 into a Tremor powerhouse, ready to conquer any terrain. The adjustable coilovers are a standout feature, providing an impressive 3.5-4.5" of front lift height over stock, facilitating the use of larger, more aggressive wheel and tire combinations. These advanced shocks, combined with ICON-engineered coil springs, ensure superior vehicle "feel" throughout the entire range of travel. Height-adjustable coilovers allow for a significant 20% increase in wheel travel compared to other ICON F-150 coilover kits, without compromising towing capacity.

ICON Tubular UCAs with Delta Joint Pro

Tubular Upper Control Arms (UCAs) with Delta Joint Pro ball joints are at the core of this system. These UCAs offer added strength, durability, and caster correction all while maintaining alignment spec range, making them the perfect companion for the extra lift height. 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.

ICON CDCV Shock Technology

The Hallmark feature of these front and rear shock absorbers is ICON's CDCV (Compression Damping Control Valve) Technology which allows you to fine-tune your shocks with ease. With 10 levels of compression damping force ranges at your fingertips, you have the power to customize your suspension to match your driving style and terrain. Whether you're navigating rocky trails, tackling uneven surfaces, or cruising down city streets, ICON's CDCV Technology ensures your ride remains smooth and controlled.

High-Quality Construction & Design

The Stage 4 Suspension System also includes vehicle-specific tuned front and rear shocks, ensuring superior damping and precise vehicle control. All shock absorbers are equipped with ICON's innovative CDC Valves, externally adjustable valves that restrict oil flow into the reservoir. This technology creates 10 levels of compression damping force ranges, allowing you to fine-tune your suspension according to your driving preferences. Furthermore, this complete package is 100% bolt-on, guaranteeing a hassle-free installation without any need for cutting or welding. The Stage 4 Suspension System is more than an upgrade for your F-150; it's a transformation that elevates your pickup's capabilities both on and off the road. With the ICON Vehicle Dynamics 2021-2024 F150 4WD Stage 4 suspension system, you're not just enhancing your F-150; you're embracing a new level of performance, precision, and control.
