About this kit

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

Rough Country 41240 is a 6-inch lift kit built around two M1 monotube shock pairs, for 2023-2026 Ford F-250 and F-350 Super Duty 4WD trucks in XL, XLT, Lariat, King Ranch, Platinum, and Limited trim. Trucks with manual-shift transfer cases, dually rear axles, or the Tremor factory trim package are not covered.

M1 monotube shocks anchor this 6-inch lift kit for the 2023-2026 Ford F-250 and F-350 Super Duty 4WD, with two application-valved pairs handling front and rear damping. Front geometry comes from a coil package plus driver- and passenger-side tubular radius arm upgrades, which allow caster to be set correctly so on-road steering feel stays close to stock. At the rear, a 6.5-inch fabricated block and U-bolt set carries the lift and is shaped to resist axle wrap. Check your transfer case, rear axle, and trim package against the exclusions first, then work from the downloadable Rough Country installation guide.
