ICON K62564L Stage 4 Susp for 2023 Ford F250/F350 Diesel - 2.5" Lift & Expansion Packs

Built specifically for the increased mass of Super Duty diesel platforms, the ICON K62564L Stage 4 Suspension System provides 2.5 inches of front lift with up to 2 inches of rear capability, engineered to maintain precise steering response and payload support where standard lift kits fail. Utilizing dual-velocity damping technology and integrated expansion packaging, this assembly manages high-energy impacts and sustained off-road loading while preserving daily drivability for 2023 Ford F250 and F350 4WD diesel trucks.

• Dual-Velocity Damping Valving: Delivers seamless adjustment between two compression tunings automatically; low-speed inputs yield compliant ride comfort on pavement, while high-speed impacts engage firm support to control bounce and protect frame components.
• Diesel-Specific Spring Rates: Calibrated shocks and springs account for the heavyweight diesel engine and transmission, ensuring proper front-end stance and rear axle tracking without excessive compression under normal payloads or towing loads.
• Integrated Expansion Packaging: Front shock absorbers include dedicated nitrogen expansion chambers to increase total fluid capacity, reducing temperature rise and extending component durability during repeated articulation or high-mileage trail use.
• Lift Measurements & Tire Clearance: Achieves a firm 2.5-inch front raise allowing clearance for tires up to 35x12.50R on stock rims, or accommodates larger 37x12.50R tires with minor inner-fender modification; rear suspension permits up to a 2-inch max lift for balanced geometry.
• Wheel & Mounting Compatibility: Optimized for aftermarket wheels with 6mm offset and 5.25-inch backspace to prevent rubbing and extend wheel-bearing lifespan; includes all required bolts, spacers, and end-links for direct replacement of factory mounting points.
• Installation Requirements & Limitations: Demands extended brake lines (Part Number 61111 recommended for single-rear-wheel models) to reach full travel; may require an adjustable track bar for lateral axle alignment; excluded from cab-and-chassis platforms and Tremor-equipped vehicles which utilize a baseline 1.5-inch lift geometry.
