About this kit
6-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 584.20 pairs a 6-inch lift with application-valved N3 series shocks for 2008-2010 Ford F-250 and F-350 Super Duty 4WD trucks. The box carries front coils, upper and lower radius arm drop brackets, an add-a-leaf, and a 3-inch block and U-bolt kit for the rear. Diesel single-rear-wheel trucks only — dually and gas engine models are not covered.
N3 shocks are the story on this 6-inch lift kit for the 2008-2010 Ford F-250 and F-350 Super Duty 4WD: they arrive valved for this application and damp both ends of the truck once the new front coils, upper and lower radius arm drop brackets, rear add-a-leaf, and 3-inch block and U-bolt kit are bolted in. The drop brackets restore caster so steering feel stays close to stock. Trucks with rear overload leafs need those leafs pulled during the build. Fitment covers XL through Harley-Davidson Edition. A downloadable installation guide is available.
