About this kit
8-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 591.20 is an 8-inch lift kit for 2005-2007 Ford F-250 and F-350 Super Duty 4WD models with a diesel engine. The kit pairs radius arm drop brackets with 6in upper and lower arms, fabricated rear blocks with a U-bolt kit, and application-valved N3 series shocks. It does not fit gas engine models or dually models.
This 8-inch lift kit for the 2005-2007 Ford F-250 and F-350 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, and Harley-Davidson Edition trims listed in the fitment section, in diesel form only — gas engine and dually trucks are outside the fitment. Radius arm drop brackets let you reset caster so steering feel stays close to factory, and the fabricated rear blocks are designed to resist axle wrap. It installs as a bolt-on job, and a downloadable Rough Country installation guide is available before you start.
