Description
Zone Offroad 4-Inch Lift Kit | Fox Adventure Shocks | 2021–2026 Ford F-150 4WD | SKU: F91F
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 Fox Adventure Series shocks. 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. If your F-150 has factory CCD (Continuously Controlled Damping), order F103 instead. If you want Nitro shocks at a lower price point, order F91N.
The Result
The Zone Offroad F91F 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. Fox Adventure Series shocks are included front and rear — Fox’s entry-level performance shock, valved specifically for the lifted F-150 geometry with improved damping consistency over Nitro shocks. Clears 35-inch tires per manufacturer specification.
