About this kit
6-Inch Vertex Lift Kit, fitment-checked
Rough Country 56550 is a 6-inch lift kit for the 2011-2014 Ford F-250 Super Duty 4WD, built around front and rear Vertex 2.5 shocks, upper and lower arm kits, coils, and a fabricated rear block with U-bolts. It does not fit F-350, gas-engine, or dually models, and it fits only trucks equipped with rear factory contact overload springs.
This 6-inch lift kit for the 2011-2014 Ford F-250 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, and Platinum trims in the fitment list. The boxed kit pairs a Vertex 2.5 shock at each corner with a 6-inch upper arm kit, lower arms, front coils, and a fabricated rear block and U-bolt package that takes the place of the factory block. Radius arm drop brackets are part of the arm hardware so caster can be set correctly after the lift. Confirm your truck has rear factory contact overload springs, then work from the downloadable Rough Country installation guide.
