Zone Offroad 5-Inch Radius Arm Lift Kit | Fox 2.0 Shocks | F-250/F-350 4WD Gas 2-Leaf | 2023-2026

Zone Offroad 5-Inch Front / 3-Inch Rear Radius Arm Lift Kit | Fox 2.0 Shocks | 2023–2026 Ford F-250 / F-350 Super Duty 4WD Gas 2-Leaf Main Spring Pack | SKU: F125

Is This for You?

This kit is for the 2023–2026 Ford F-250 or F-350 Super Duty 4WD owner with a gas engine and a 2-leaf main spring pack who wants 5 inches of front lift and 3 inches of rear lift with Fox 2.0 shocks included. Two independent fitment gates must be confirmed before ordering: engine type (gas only — not diesel) and rear spring pack configuration (2-leaf main only — not 3-leaf). If your Super Duty has a 6.7L Power Stroke diesel, this kit will not fit. If your rear spring pack has 3 leaves, order F126 instead. If your truck is 2WD, this kit will not fit. If you want maximum lift, see F128 (7-inch/4.5-inch).

The Result

The Zone Offroad F125 delivers 5 inches of front lift and 3 inches of rear lift on the 2023–2026 Super Duty solid front axle platform. Heavy-duty replacement radius arms re-establish proper caster geometry at 5 inches of front lift — critical on the radius arm solid axle platform where factory arms create significant caster misalignment at lift height. Reinforced front crossmembers maintain structural rigidity. Front coil spacers and bump stop extensions complete the front lift. Fox 2.0 shocks are included front and rear, valved for the lifted Super Duty geometry. A 3-inch rear block spacer provides rear lift.

Radius Arm System — Why Radius Arms Are Required

• The 2023–2026 F-250/F-350 Super Duty 4WD uses a radius arm front suspension with a solid front axle.
• At 5 inches of front lift, factory radius arms create significant caster misalignment — degrading steering precision and on-road stability.
• Zone Offroad heavy-duty replacement radius arms re-establish proper caster geometry at full lift height. This is not a spacer-only kit — radius arm replacement is required for correct geometry at this lift height.
