About this kit
6-Inch Lift Kit with Vertex Shocks, fitment-checked
Rough Country 57859 is a 6-inch lift kit for 2005-2007 Ford F-250 and F-350 Super Duty 4WD trucks, built around adjustable Vertex 2.5 front units and matched Vertex 2.5 rear shocks. It does not fit dually models, and the exhaust must be modified for front driveshaft clearance.
This 6-inch lift kit for the 2005-2007 Ford Super Duty 4WD covers F-250 and F-350 applications from XL and XLT through Lariat, King Ranch, and Harley-Davidson Edition, as listed in the fitment section. The kit pairs left- and right-hand adjustable Vertex 2.5 front units with two Vertex 2.5 rear shocks, and adds upper and lower arm assemblies, a rear add-a-leaf, and a 3 inch block and U-bolt kit. Radius arm drop brackets set caster back toward factory geometry for handling. Confirm the dually exclusion and plan the exhaust modification before you start.
