Replace your collapsed factory struts with a fully load-rated coilover system engineered for extreme articulation and heavy payload retention

The ICON K63178RL Coilover Conversion Kit removes the stock 2023 Ford F250/F350 strut assembly and installs a 4-to-5.5-inch adjustable lift package built around CNC-machined aluminum shocks, high-cycle progressive-rate springs, and reinforced lower radius arms. This complete removal-and-rebuild architecture restores proper suspension geometry instead of stacking metal spacers on top of worn OEM components.

• Dual remote expansion packs on the monotube shocks increase oil-and-gas fluid capacity for rapid heat dissipation during sustained trail running or towing near GVWR limits.
• Preloaded coil springs feature a spring rate calibrated to support unloaded Super Duty weights while resisting bottoming when equipped with aftermarket bump-out fenders and larger tires.
• CNC-aluminum radius arms maintain correct pinion angles and tie-rod alignment, preventing the accelerated CV shaft and ball joint wear typical of rigid-block lifts.
• Bronze-lined spherical joints and hard-anodized bump cushions absorb repeated rock strikes that normally fracture factory rubber mounts and cause steering kickback.
• Direct bolt-in architecture aligns with existing 2015–2023 Super Duty mounting points, utilizing standard hardware and requiring zero frame modification or crossmember removal.
• Constructed from aircraft-grade aluminum housings, chromoly internals, and corrosion-resistant powder coatings, covered by ICON’s limited lifetime warranty against seal failures and structural finish defects.
