About this kit
4-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 49540 is a 4-inch lift kit for the 1999-2004 Ford F-250 and F-350 Super Duty 4WD. Front height comes from a pair of 4-inch leaf springs; the rear rides on a 3-inch block and U-bolt kit. Two pairs of M1 monotube shocks are included. Not for V-8 gas engine trucks, dually trucks, or units built before 3-1-1999.
Height on this 4-inch lift kit for the 1999-2004 Ford Super Duty 4WD is split front to rear: 4-inch front leaf springs pair with a 3-inch rear block and U-bolt kit, which brings the nose up level with the back of the truck and adds ground clearance. Also boxed are a universal U-bolt kit, a hardware box kit, and two pairs of M1 monotube shocks valved for this application. Fitment covers F-250, F-250 Super Duty, and F-350 Super Duty in XL, XLT, Lariat, King Ranch, and Harley-Davidson Edition trim. A downloadable Rough Country installation guide is available for the bolt-on work.
