Product Description

The ICON K93142L Stage 2 Suspension Lift Kit is a comprehensive suspension upgrade engineered for 2021-2023 Ford F‑150 4WD owners who want serious lift, improved suspension travel, and durability for both on‑road comfort and off‑road performance. The adjustable front coilovers deliver 3.5-4.5″ of lift — enough to accommodate larger wheels and aggressive tires while improving ground clearance for trail work or heavy‑duty use. Billet upper control arms with Delta Joint PRO ball joints and heavy‑duty knuckles maintain proper suspension geometry under load and lift, ensuring stable handling and improved articulation.

At the rear, the multi‑rate leaf pack gives owners flexibility to customize spring stiffness and ride height depending on load — whether you run light, daily driving, or carry heavy cargo or towing loads. The tuned rear shocks and leaf‑pack configuration enhance load‑handling, reduce axle wrap, and improve ride quality compared to stock leaf springs. The 20% increase in front wheel travel further improves suspension compliance and off‑road capability. Designed as a bolt‑on system using factory mounting points, installation is straightforward without the need for cut/weld modifications. For F‑150 owners wanting a balanced over‑landing/off‑road-ready suspension system with lift, strength, and customizability — ICON K93142L is a well-rounded, high-performance solution.
