The ICON 2.5 Series Coilover Kit (Part #K93133) upgrades 2021–2024 Ford F-150 4WD suspensions with a 2.75–3.5-inch adjustable front lift, integrated upper control arms, and bypass-shock valving for predictable handling on technical terrain.

• Material composition: Shock bodies, external reservoirs, and mounting hardware are machined from 6061-T6 billet aluminum with a hard anodic layer, while internally polished bores and Teflon-coated piston shafts limit metal wear and block particulate contamination.
• Lift range and capacity: Front coilovers allow mechanical preload adjustment across a 2.75-to-3.5-inch stroke window, matching rear unit spacing to preserve track width, differential pinion angles, and OEM-rated payload distribution.
• Valve architecture: Flow-controlled internals react to impact frequency rather than pure compression depth, maintaining wheel traction over loose rocks and rutted washes while stabilizing chassis oscillation on graded dirt and asphalt.
• Fitting compatibility: Precision spherical joints replicate factory steering knuckle pickup points, enabling direct bolt-up using existing axle brackets, brake rotors, and CV u-joints without cutting, grinding, or swapping lower control arms.
• Sealed maintenance design: Double-lip polymer wipers hold lubricant inside the shock tube and prevent water migration during stream crossings, extending rebuild intervals well past open-boot suspension architectures.
• Structural warranty: Manufactured to automotive OEM dimensional tolerances with a three-year limited guarantee covering material defects and seal failure under standard off-road operating loads.
