About this kit
6-Inch Lift Kit with Vertex Shocks, fitment-checked
Rough Country 53959 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 matched 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 for front driveshaft clearance.
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 carries left and right adjustable Vertex 2.5 front coilovers, a pair of Vertex 2.5 rear shocks, an add-a-leaf, a 3-inch fabricated block and U-bolt kit, and two radius arm upgrade boxes with rubber-bushed arms that hold factory geometry. An axle-end alignment cam allows caster adjustment. Confirm dually and gas-exhaust caveats first, then work from the downloadable installation guide.
