About this kit
6-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 41640 is a 6-inch lift kit for 2023-2026 Ford F-250 and F-350 Super Duty 4WD trucks, built around tubular radius arms, front coils, M1 monotube shock pairs, and a 6.5 in fabricated rear block and U-bolt kit. It does not fit dually models, trucks with a manual shift transfer case, or the Tremor Factory Trim Package.
This 6-inch lift kit for the 2023-2026 Ford F-250/F-350 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, and Platinum trims listed in the fitment section. The tubular radius arms reset caster so steering behavior stays close to factory, and two M1 monotube shock pairs are valved for this application. The rear uses a fabricated 6.5 in anti-axle-wrap block with a matching U-bolt kit. Confirm your transfer case type, rear axle configuration, and trim package against the exclusions before ordering; a downloadable installation guide is available for planning the job.
