8-Inch Lift Kit with N3 Shocks, fitment-checked

Rough Country 590.20 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 6-inch upper and lower radius arm components with rear leaf springs, a universal 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 Super Duty 4WD covers F-250 and F-350 applications in XL, XLT, Lariat, King Ranch, and Harley-Davidson Edition trim. Radius arm drop brackets let you set caster back where the factory intended, which keeps steering and driveability closer to stock. Front lift is matched to the rear leaf springs so the truck sits level rather than nose-down. Confirm you have a diesel, non-dually truck before ordering, then work through the downloadable Rough Country installation guide to plan the job.
