Icon Vehicle Dynamics K64543L Stage 3 EXP Suspension Lift Kit Lift 4.5" Ford F-250/F-350 23-26

ICON Vehicle Dynamics 4.5" Stage 3 Suspension System

This Stage 3 suspension system for 2023–2025 Ford F-250 / F-350 Super Duty 4WD diesel applications provides significant lift and improved ride quality for on-road, towing, and off-road use. The kit combines dual-rate coil springs, tuned internal reservoir shocks, and geometry-correcting brackets to allow larger tire fitment while maintaining control and comfort over varied terrain.

• Fitment: 2023–2025 Ford F-250 / F-350 4WD diesel applications.
• Front lift: 4.5" over stock (standard); 3.5" with certain factory off-road packages.
• Rear lift: Approximately 2" via leaf spring expansion packs.
• Coil springs: ICON engineered dual-rate design optimized for diesel trucks — softer initial rate for on-road comfort and firmer secondary rate for bottoming resistance and off-road performance.
• Shocks: ICON 2.5 Aluminum Series internal reservoir front and rear shocks with vehicle-specific tuning for improved handling and ride quality; corrosion-resistant anodized bodies; fully rebuildable and re-tunable.
• Steering control: Fabricated track bar drop bracket to reduce bump steer and center the axle; dual opposing steering stabilizer kit improves steering damping for larger tire setups.
• Geometry correction: Fabricated radius arm drop brackets correct suspension geometry and caster for proper alignment.
• Rear performance: Leaf spring expansion packs provide rear lift with improved ride quality and reduced axle wrap compared to lift blocks.
• Included hardware: Front sway bar drop brackets to prevent bind, heavy-duty aluminum bump stop spacers, and stainless steel braided extended brake lines.
• Durability: High-quality CNC-machined, laser-cut, and brake-formed components with lifetime guarantees against spring breakage or sagging and against fabricated component defects.
• Travel improvement: Approximately 50% increased front wheel travel over stock for enhanced off-road capability.

Key specifications and recommendations: Supports fitment of up to 37" x 12.50" tires (larger tires may require fender trimming or modifications). Recommended aftermarket wheel offsets are approximately 6 mm; commonly compatible wheel sizes include 17x8.5, 18x9, and 20x9 (verify fitment for specific wheel/backspace combinations).

Notes

• Only fits 4WD models; does not fit F-350/F-450 cab & chassis models.
• Springs are rated for diesel-engine applications only.
• Lift heights indicated are for a stock-equipped vehicle and are based on typical 4WD crew cab diesel configurations; actual lift may vary with vehicle options and equipment.
• Fits single rear wheel (SRW) models only.
• Requires recalibration of Advanced Driver Assistance Systems (ADAS) after installation.
• Vehicles equipped with dynamic bending headlamps, onboard scale systems, or similar factory options may require additional components or modifications.
• Reduction in rear spring rate may reduce accuracy of onboard scale systems, if equipped.
• Shocks are fully serviceable.
• OEM wheels and tires will fit; aftermarket tire and wheel combinations should be verified before purchase and may require trimming or other modifications.
• Use with an adjustable track bar (sold separately) is recommended to ensure proper axle centering and alignment after installation.
