Zone Offroad 4-Inch Lift Kit | Nitro Shocks | Ford F-150 4WD | 2021-2026

Zone Offroad 4-Inch Lift Kit | Nitro Shocks | 2021–2026 Ford F-150 4WD | SKU: F91N

Is This for You?

This kit is for the 2021–2026 Ford F-150 4WD owner who wants 4 inches of front lift with corrected suspension geometry and Nitro gas shocks at the entry price point. Clears 35-inch tires per manufacturer specification. If your F-150 is 2WD, this kit will not fit — see the 2WD-specific kits instead. If your F-150 is a Raptor or Tremor, this kit will not fit — those trims require platform-specific kits. If your F-150 has factory CCD (Continuously Controlled Damping), order F103 instead. If you want Fox Adventure Series shocks, order F91F.

The Result

The Zone Offroad F91N delivers 4 inches of front lift on the 2021–2026 F-150 4WD platform with corrected caster, camber, and scrub radius geometry via heavy-duty crossmembers and steering knuckles. Differential drop brackets correct CV axle angles at lifted height to reduce vibration and premature wear. Nitro gas shocks are included front and rear, valved for the lifted F-150 geometry. Clears 35-inch tires per manufacturer specification — verify clearance with your specific wheel offset before ordering.
