Icon Vehicle Dynamics K65890R Stage 1 Suspension Lift Kit Lift 2.5" Ford F-250/F-350/F-450 23-26

ICON Vehicle Dynamics

This Stage 1 2.5" suspension system is engineered for 2023–2025 Ford F-250 / F-350 Super Duty 4WD diesel trucks. Designed for on-road and light-duty off-road use, the package improves ride quality, increases wheel travel, and maintains towing capacity while providing increased tire clearance and long-term durability.

• 2.5" front lift using ICON-engineered dual-rate coil springs (Tremor-equipped trucks see a 1.5" front lift)
• Vehicle-specific tuned internal-reservoir 2.0 Aluminum Series shocks — fully serviceable, rebuildable and re-tunable
• Fabricated, fully boxed radius arms with sealed pivot bushings for reduced road feedback, on-vehicle caster adjustment, increased strength, and improved tire clearance at full steering lock
• Tire clearance optimized to clear up to 37" tall tires without contacting the radius arm (37" may require minor fender trimming in some configurations)
• Improved ride and handling — increased wheel travel, reduced body roll versus stock
• Durability and serviceability — springs backed by a lifetime guarantee against sagging or breakage; shocks fully serviceable
• 100% bolt-on installation — no drilling, cutting or welding required; no driveshaft modifications required
