About this kit
6-Inch Lift Kit with Vertex 2.5 Shocks, fitment-checked
Rough Country 57950 is a 6-inch lift kit for 2005-2007 Ford F-250 and F-350 Super Duty 4WD trucks, built around four Vertex 2.5 shocks, radius arm drop brackets, front coils, and a rear block and add-a-leaf package. It does not fit gas engine trucks, dually axles, or trucks running rear overload springs.
This 6-inch lift kit for the 2005-2007 Ford F-250 and F-350 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, and Harley-Davidson Edition trims. The kit ships with upper and lower 6-inch arm assemblies, front D-Coils, an add-a-leaf, and a 3-inch block and U-bolt set for the rear, plus two front and two rear Vertex 2.5 shocks. Drop brackets let you reset caster so steering feel stays close to factory. Confirm your truck is diesel-powered, single rear wheel, and free of rear overload springs before ordering, and pull the downloadable installation guide first.
