Restores Proper Alignment on 2023 Ford Super Duty with ICON 4.5-Inch Stage 4 Radius Arms

Solve driveline vibration and handling instability on lifted platforms with the ICON 4.5-inch Stage 4 suspension system for 2023 Ford F-250 and F-350 gas models, featuring custom radius arms that reposition the rear axle for accurate geometry and safe operation.

• Exact Model Year Application: Calibrated exclusively for 2023 Ford F-250 and F-350 gas configurations, ensuring proper clearance and structural integration without fitment conflicts associated with diesel variants or chassis revisions in other years.
• Driveline Geometry Correction: The included radius arms restore the rear spring perch location to optimal alignment levels, counteracting the forward axle shift caused by the 4.5-inch lift and preserving correct CV angles to prevent premature U-joint wear.
• Component Ecosystem Integration: System design coordinates with recommended accessories such as extended brake line kits, ensuring all critical connections remain properly sized and safely rated for the increased suspension travel and extension.
• Controlled Lift Dimensions: Delivers a measured 4.5-inch height gain that creates substantial room for larger tire diameters and improves approach angles while maintaining predictable steering response and stable highway traction characteristics.
• Heavy-Duty Strength Upgrade: Replaces weakened factory pivot components with high-tolerance aftermarket engineering built to manage Super Duty payload requirements and the torque loads generated by the 6.8-liter V8 gas powerplants.
