About this kit

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

Rough Country 54040 is a 6-inch lift kit for the 2011-2014 Ford F-250 Super Duty 4WD in King Ranch, Lariat, Platinum, XL, and XLT trims. The kit pairs front D-Coil springs and upgraded radius arms with two M1 monotube shock pairs. It does not fit F-350, dually, or gas-engine trucks, and the truck must have rear factory contact overload springs.

This 6-inch lift kit for the 2011-2014 Ford F-250 Super Duty 4WD is a bolt-on package built around front D-Coil springs, two M1 monotube shock pairs, and a pair of radius arm upgrade boxes that keep front geometry close to factory angles and add an adjustable cam at the axle for caster correction. Out back, fabricated anti-axle-wrap blocks and a U-bolt kit handle the rear height. Confirm your truck has factory contact overload springs and a diesel engine before ordering, then work through the downloadable Rough Country installation guide.
