Restore factory steering precision and eliminate front-end wallow with the ICON Stage 4 Coilover Conversion Kit featuring upgraded radius arms for 2011–2016 Ford F-250 and F-350 platforms.

This engineered suspension solution replaces rigid stock coilovers with high-displacement monotube shock assemblies and custom progressive springs, delivering controlled articulation without compromising highway stability or payload limits.

• Direct OEM Mounting Designed specifically for 2011 through 2016 Ford F-250 and F-350 4x4 trucks, matching exact chassis mounting points to prevent bracket binding, speed up installation, and preserve factory crash safety structures.
• Measured Lift & Fine Tuning Provides a secure 4–5.5 inch front elevation, achieved through multi-threaded collar adjustments that let you dial in stance, tire clearance, and approach angles without modifying brake lines or sway bar mounts.
• Geometry-Stabilizing Radius Arms Replaces torsion-prone factory upper arms with reinforced units that correct lost caster angles, eliminate bump steer, and maintain consistent wheel alignment under heavy acceleration and rough terrain.
• Corrosion-Resistant Construction Built with 6061-T6 aluminum spring perches and grade-8 stainless fasteners, the system fights fatigue cracking and salt degradation while holding torque specifications consistently after years of washboard exposure.
• Heat-Dissipating Damping Uses large-volume monotube chambers and precision-tuned piston valving to pull heat away from the fluid faster than conventional twin-tube shocks, preventing compression fade during consecutive trail descents.
• OEM Load Compatibility Calibrated to match factory spring rates, allowing owners to tow trailers, haul toolboxes, and carry fifth-wheel payloads without inducing rear chassis sag or hitch-dive instability.
• Manufacturer Protection Backed by a comprehensive warranty against defects in materials and workmanship, ensuring long-term reliability for commercial route vehicles and off-road builds alike.
