About this kit
4.5-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 56740 is a 4.5-inch lift kit for 2015–2016 Ford F-250 Super Duty 4WD trucks, built around two M1 monotube shock pairs, radius arm drop brackets, front coils, and a 6.5in fabricated block and U-bolt kit. It fits only trucks with overload springs, and does not fit F-350, gas-engine, or dually models.
This 4.5-inch lift kit for the 2015–2016 Ford F-250 Super Duty 4WD covers King Ranch, Lariat, Platinum, XL, and XLT trims listed in the fitment section. The radius arm drop brackets reset caster so steering geometry stays close to factory, and the rear uses a fabricated 6.5in block with matched U-bolts. Confirm your truck has overload springs before ordering; F-350, gas-engine, and dually applications are excluded. Trucks with a two-piece rear driveshaft also need a carrier bearing drop bracket, sold separately. A downloadable Rough Country installation guide is available for planning the job.
