About this kit
6-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 58940 is a 6-inch lift kit for the 2015–2016 Ford F-250 Super Duty 4WD in XL, XLT, Lariat, King Ranch, and Platinum trims. Two pairs of M1 monotube shocks, upper and lower arm kits, a coil set, and a fabricated rear block with U-bolts make up the package. It does not fit F-350, gas-engine, or dually trucks, and the truck must have factory rear contact overload springs.
This 6-inch lift kit for the 2015–2016 Ford F-250 Super Duty 4WD bolts on with radius arm drop brackets that let you set caster back where the factory intended, so steering feel and driveability stay familiar. Front lift brings the nose level with the rear and opens up ground clearance, while the fabricated rear block replaces the factory unit and is shaped to resist axle wrap. Confirm your truck has rear factory contact overload springs and is not an F-350, gas, or dually application, then work through the downloadable Rough Country installation guide before you start.
