About this kit
6-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 594.20 is a 6-inch lift kit for 2008-2010 Ford F-250 and F-350 Super Duty 4WD trucks, built around front D-Coils, an add-a-leaf, a 3 inch block and U-bolt set, and N3 series shocks. Gas engine trucks and dually models are not covered. Trucks with rear overload leafs require those leafs to come out during the build.
This 6-inch lift kit for the 2008-2010 Ford F-250 and 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 kit bolts on and pairs front D-Coils with a rear add-a-leaf and 3 inch block and U-bolt kit, so the front sits level with the rear. Radius arm drop brackets keep caster where the factory geometry wants it. Application-valved N3 shocks handle damping on and off pavement. A downloadable Rough Country installation guide is available before you start.
