ICON 2023 Ford F‑250/F‑350 Stage 5 Coilover Conversion Kit with Expansion Packs

Replace worn factory suspension with precision-valved coilovers calibrated to stabilize your 2023 Super Duty through heavy loads, high-speed impacts, and technical off-road terrain.

• Specified 2.5–3 Inch Lift Profile: Restores proper CV angularity and thrust alignment on the 4WD gas chassis while providing secure clearance for up to 35-inch tires without trimming.
• Remote Reservoir Dual-Chamber Valving: Isolates nitrogen gas from damping fluid to prevent cavitation and heat fade during sustained desert running or towing, delivering consistent shock response at highway and crawl speeds alike.
• Expansion Pack Progressive Bump Stops: Channels bolt alongside rear shocks to absorb last-percent deflection, dissipating violent compressions before they transfer to the frame and preserving interior NVH levels.
• CNC Billet Aluminum Shock Housings: Finned thermal masses paired with hard-chrome alloy shafts shed operating temperature rapidly and resist road salt, sand, and moisture corrosion significantly longer than stamped steel units.
• Direct-Factory Mounting Geometry: Uses existing knuckle towers and lower A-arm pads to complete swap without cutting, drilling, or aftermarket control arms; drops straight into the OE bay with standard socket sets.
• Super Duty Payload Calibration: Spring rates and shim stacks tuned for the Gen 17 heavyweight architecture, balancing compliant daily ride quality with controlled lateral body roll when carrying gear or flat-towing trailers.

This conversion system replaces the complete front and rear spring-shock assemblies, correcting the compromised geometry that leads to premature u-joint wear and nervous steering feedback in stock trucks. Built exclusively for 2023 Ford F‑250 and F‑350 four-wheel-drive models equipped with gasoline engines; does not fit diesel applications, two-wheel-drive platforms, or cab-and-chassis variants. For 37-inch tire diameters, recommend extended brake line routing and aftermarket wheels with 6mm negative offset and 4.75-inch backspace to guarantee full wheel travel without fender contact. Professional installation, proper torque sequencing, and multi-point alignment are advised to protect driveline components and ensure safe, long-term operation.
