About this kit

6-Inch Lift Kit with M1 Shocks, fitment-checked

Rough Country 49740 is a 6-inch lift kit for 1999-2004 Ford F-250 and F-350 Super Duty 4WD trucks, built around front and rear leaf springs and two pairs of M1 monotube shocks. It does not fit V-8 gas engine trucks, dually models, or trucks built before 3-1-1999. Trucks with a 2-piece rear driveshaft also need a carrier bearing drop bracket, which is not part of this kit.

This 6-inch lift kit for the 1999-2004 Ford F-250/F-350 Super Duty 4WD ships as a bolt-on package: 6-inch front and rear leaf springs, a pitman arm, a box kit shared with the Excursion application, two universal u-bolt kits, and two pairs of application-valved M1 monotube shocks tuned for street and trail use. Coverage runs from XL and XLT through Lariat, King Ranch, and Harley-Davidson Edition trims. Confirm your engine, rear axle, and build date against the exclusions first, then work from the downloadable Rough Country installation guide.
