About this kit
6-Inch Lift Kit with Vertex Coilovers, fitment-checked
Rough Country 56559 is a 6-inch lift kit for the 2011-2014 Ford F-250 Super Duty 4WD in King Ranch, Lariat, Platinum, XL, and XLT trims. It pairs adjustable Vertex 2.5 front coilovers with Vertex 2.5 rear shocks, radius arm drop brackets, and fabricated rear blocks. It does not fit F-350, gas-engine, or dually trucks.
This 6-inch lift kit for the 2011-2014 Ford F-250 Super Duty 4WD converts the front to a Vertex 2.5 adjustable coilover setup rated across the 4.5 in to 6 in range, with matching Vertex 2.5 rear shocks. Radius arm drop brackets reset caster so steering behavior stays close to factory, and the fabricated rear block replaces the original block. Before ordering, confirm your truck is a diesel, single-rear-wheel F-250 and check whether the rear leaf packs carry a factory contact overload spring, since that changes what you need.
