About this kit
6-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 579.20 lifts the 2005-2007 Ford F-250 and F-350 Super Duty 4WD six inches on application-valved N3 series shocks. The box carries a 6in D-Coil set, upper and lower 6in arm kits, a rear add-a-leaf, and a 3 inch block and U-bolt kit. Diesel, single-rear-wheel trucks only; not for models running rear overload springs.
N3 series shocks are the anchor of this 6-inch lift kit for the 2005-2007 Ford Super Duty 4WD, valved for this application so on-road manners and off-road travel stay in balance. Fitment covers F-250 Super Duty and F-350 Super Duty 4WD in XL, XLT, Lariat, King Ranch, and Harley-Davidson Edition trim. Radius arm drop brackets keep caster in the correct range, and the front ride height comes up to match the rear. Gas-engine trucks, duallys, and trucks with rear overload springs are excluded. A downloadable Rough Country installation guide is available for this bolt-on job.
