About this kit
6-Inch Lift Kit with Vertex Shocks, fitment-checked
Rough Country 53859 is a 6-inch lift kit for 2008–2010 Ford F-250 and F-350 Super Duty 4WD trucks, built around adjustable Vertex 2.5 front coilovers and Vertex 2.5 rear shocks. It does not fit dually models. The factory rear contact overload springs come out during the build, and gas trucks may need exhaust work to clear the front driveshaft.
This 6-inch lift kit for the 2008–2010 Ford F-250/F-350 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, FX4, Cabela's, and Harley-Davidson Edition trims listed in the fitment section. The box pairs left- and right-hand adjustable Vertex 2.5 front coilovers with a pair of Vertex 2.5 rear shocks, two radius arm upgrade boxes, an add-a-leaf, and a 3-inch fabricated block and U-bolt kit. Rough Country calls the installation bolt-on, with an adjustable cam at the axle for caster. Check the dually and overload-spring notes first, then work from the downloadable installation guide.
