6 Inch Lift Kit | Diesel | Ovld | Ford F-250 Super Duty 4wd (2011-2014)

Built for F-250 Super Duty owners who want more ground clearance and tire capacity without sacrificing ride quality, this 6-inch Rough Country lift kit transforms your diesel truck for serious off-road performance. You'll gain up to 37-inch tire clearance while preserving factory handling through properly-set caster geometry — no binding, no compromises.

What's included

• 6-inch D-Coil springs — lifted coil springs engineered to support your truck's weight while delivering the full 6-inch rise.
• Radius arm drop brackets — allow caster to be set correctly, maintaining factory handling and driveability on pavement and trail.
• Fabricated anti-wrap rear blocks — stronger and longer-lasting than cast alternatives; specially designed to prevent axle wrap and binding while preserving stock ride quality.
• N2.0 series shock absorbers — nitrogen-charged for balanced on-and-off-road performance and a smooth highway ride.
• Extended stainless steel brake lines and brackets — ensure proper brake function after the lift without stress on factory hoses.

Important notes

• Diesel engines only — does not fit gas F-250 models.
• Does not fit F-350 or dually configurations.
• Not compatible with factory rear contact overload springs — those must be removed or swapped for this kit.
• Recommended tire range is 35–37 inches to maintain proper geometry and clearance.
