Built for F‑150 owners who demand maximum control, predictable handling, and increased suspension capability under real‑world load. ICON’s Stage 4 Billet CDXS System delivers a fully engineered 3.5–4.5" lift using CDXS coilovers, billet upper control arms, Tremor‑geometry steering knuckles, and a full replacement leaf pack designed for stability, articulation, and weight management.
This system is tuned for trucks that tow, haul, and see mixed terrain. The CDXS coilovers increase wheel travel and damping precision, while the billet UCAs maintain alignment and ball‑joint angles at lift height. The full leaf pack improves load support and rear‑end composure without sacrificing ride quality.
