3-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 43640 is a 3-inch lift kit for compatible 2023–2024 Ford F-250 Super Duty 4WD models, built around front 3.0-inch coils, radius arm drop brackets, a rear block and U-bolt kit, and two M1 monotube shock pairs. It is a diesel-only application: gas, F-350, dually, and Tremor package trucks are excluded.
This 3-inch lift kit for the 2023–2024 Ford F-250 Super Duty 4WD covers King Ranch, Lariat, Limited, Platinum, XL, and XLT trims shown in the fitment section. Front 3.0-inch coils lift the nose to even out factory rake, while the radius arm drop brackets bring caster back into range for predictable steering. Rear blocks and U-bolts finish the height, and M1 monotube shocks damp both ends. Trucks with a factory top-mounted overload spring need longer U-bolts, SKU 7669. Bolt-on installation with standard hand tools; a downloadable Rough Country installation guide is available.
