ICON Stage 8 Suspension System for 2023+ Ford F250/F350 (Gas) – 4.5" Lift

Deliver a precise 4.5-inch lift over stock on 2023 and newer Ford F250 and F350 gasoline Super Duty trucks, engineered to accommodate aggressive tire sizes while preserving driveline geometry, payload capacity, and daily drivability.

• Critical Gas-Only Compatibility: Calibrated specifically for Ford F250/F350 models powered by gasoline engines; this kit will not fit diesel variants due to distinct frame structures, engine packaging, and clearance requirements unique to the diesel powertrain options.
• Expansion Pack Thermal Management: Features integrated expansion packs that increase internal fluid volume and separate the damping oil from the nitrogen charge, preventing horsepower loss and fade during sustained high-cycle off-road running or heavy towing applications.
• Factory Geometry Preservation: Stage 8 performance tuning maintains correct lower control arm angles and pinion operating parameters across the full 4.5-inch lift range, reducing U-joint stress and minimizing steering wander compared to traditional block-lift methods.
• Bolt-On Installation without Drilling: Replaces front struts and rear shocks directly at factory attachment points; utilizes existing bearing surfaces, sway bar links, and brake line routing to eliminate cutting, welding, or structural modification to the Super Duty chassis.
• Heavy-Duty Shock Body Construction: Built around robust shock bodies with precision-welded mounting tabs and corrosion-resistant finishes, designed to withstand the severe torsional loads, rock impacts, and vibration characteristics inherent to dually and Super Duty pickups.
• Fine-Tune Adjustable Perches: Includes spring collars that allow iterative height adjustments within the 4.5-inch range, enabling accurate leveling of rake, optimization of approach/departure angles, and compensation for suspension sag under varying payload conditions.

This suspension kit targets owners seeking maximum travel and clarity over rough terrain without sacrificing the structural integrity of their workhorse trucks. The direct-fit design ensures compatibility with stock wheel bearings and hub assemblies, while the inclusion of expansion packs addresses the primary weakness of basic lift shocks—heat accumulation—making this setup suitable for demanding environments ranging from desert runabouts and rock crawling trails to mixed day-to-day highway use. Proper alignment and torque verification are recommended after installation to ensure optimal component longevity and safe operation.
