Complete 2023 Ford F-250/F-350 4–5.5‑Inch Stage 9 Coilover Suspension Conversion Kit

Replacing factory torsion bars with adjustable 2.5‑inch coilovers, custom radius arms, and expansion‑pack reservoirs, this ICON Stage 9 system delivers progressive, high‑travel suspension performance that remains stable on paved roads and predictable during aggressive off‑road use.

• Exact 2023 Super Duty Fitment: Catalog‑matched to 2023 F‑250 and F‑350 spindle heights and upper control arm bolt patterns, ensuring direct installation without cutting or welding.
• Controlled 4–5.5 Inch Lift: Raises the front ride height uniformly while providing accessible compression and rebound tuning, properly supporting heavier bumpers, winches, and aftermarket accessories.
• Expansion Pack Air Bypass: Utilizes progressive internal air chambers to absorb consecutive trail strikes smoothly, eliminating the harsh bottoming feel common with rigid basic shock setups.
• Billet Aluminum & Chromoly Construction: Built with hard‑anodized forged shock bodies, nitrogen‑charged monotube internals, and precision‑turned steel pivot hardware to resist impact deformation and road salt corrosion.
• Driveline Geometry Correction: Includes reinforced replacement radius arms that restore proper track bar linkage and differential pinion angles, protecting CV joints and steering components from accelerated wear.
• 37‑Inch to 39‑Inch Tire Ready: Extended shock stroke and calibrated bump stops clear large tread blocks with minimal fender trimming, maintaining safe ground clearance and articulation limits.
