About this kit
6-Inch Lift Kit with Vertex Shocks, fitment-checked
Rough Country 59659 is a 6-inch lift kit for 2005-2007 Ford F-250 and F-350 Super Duty 4WD trucks. It pairs adjustable Vertex 2.5 front coilovers (4.5 in to 6 in) with a pair of Vertex 2.5 rear shocks, an add-a-leaf, and a 3-inch block and U-bolt kit. Dually models are not covered, and trucks with rear overload leafs require those leafs to come out during the build.
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 applications listed in the fitment section. The Vertex 2.5 front coilovers are handed left and right and adjust across a 4.5 in to 6 in range, while rear height comes from the add-a-leaf and the 3-inch block and U-bolt kit. Radius arm drop brackets let you set caster back where the factory geometry wants it, so steering feel stays predictable. Confirm your truck is not a dually and check for rear overload leafs before you start.
