What's included

• 6-inch lift kit box — complete foundation for the suspension raise, precision-engineered for your Super Duty.
• N3 Shock Kit — factory-valved absorbers tuned for balanced on- and off-road performance.
• 6.5-inch block U-bolt kit with overloads — fabricated rear blocks prevent axle wrap and binding while maintaining stock ride quality.
• Front CV driveshaft — diesel-rated front driveshaft accommodates the lifted geometry without binding or vibration.
• 6-inch coil box — precision-fit lifted coil springs work with radius arm drop brackets to keep suspension angles as close to factory as possible.
• Radius arm drop brackets — allow proper caster correction to preserve factory handling and driveability after the lift.

Important notes

• Fits 4WD F-250 Super Duty (2017–2022) only — does NOT fit F-350 dually models or F-350 single-rear-wheel models.
• Requires factory-equipped rear contact overload springs — will not work on models without them.
• Does NOT fit manual shift transfer cases, gas engine models, or models with 4-inch rear axle tubes.
