ICON 2.5‑Inch Series Dual Remote Reservoir Shock Upgrade for 2023–Present Ford F250/F350 (Gas) | 4.5‑Inch Stage 8 Lift System

Delivers a precisely controlled 4.5‑inch lift with industry-leading heat dissipation and load-matching valving, transforming heavy-duty Super Duty ride quality without sacrificing factory towing capacity or requiring frame fabrication.

• 2.5‑Inch Monotube Architecture with 6061‑T6 Aluminum Reservoirs: A larger primary tube and twin TIG-welded aluminum remote reservoirs drastically increase piston surface area and oil volume, eliminating siphon cavitation and damping fade during extended desert runs or steep mountain descents.
• Factory-Mount Bolt-On Compatibility: Directly replaces the OEM front and rear struts/shocks using existing chassis holes, preserving ride height sensors and electronic stability calibration while upgrading internal valving to match progressive spring rates.
• 16-Click External Compression Adjustment: Allows on-vehicle tuning of initial stroke compliance versus high-speed impact absorption so you can dial out squat under acceleration, stiffen for loaded hauling, or soften for rock crawling without disconnecting components.
• Geometry-Correcting Stage 8 Hardware Bundle: Includes precision-machined track bar relocation brackets and alignment spacers that restore proper pin angle and caster, neutralizing steering wandering, bump steer, and tire scrub common on oversized lifts.
• Corrosion-Resistant Construction & Nitrogen Pre-Charge: Hardened chromoly piston rods, low-friction double-lip shaft seals, and a stabilized helium-nitrogen gas charge ensure consistent damping across extreme temperature swings while resisting road salt, mud ingestion, and UV degradation.
• Load-Rated Durability Backed by Manufacturer Guarantee: Engineered to support maximum factory GVWR and payload ratings without bottoming out, with a limited lifetime warranty covering structural fatigue, seal failure, and finish defects under normal operating conditions.
