About this kit
3-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 48640 is a 3-inch lift kit for 2005–2007 Ford F-250 and F-350 Super Duty 4WD trucks. The kit pairs front coils and a 2-inch rear block and U-bolt package with two M1 monotube shock pairs, plus radius arm drop brackets to keep caster where it belongs. Dually models are not covered.
This 3-inch lift kit for the 2005–2007 Ford Super Duty 4WD covers F-250 and F-350 applications from XL and XLT up through Lariat, King Ranch, and the Harley-Davidson Edition, as listed in the fitment section. It bolts on with front coils, a 2-inch rear block and U-bolt kit, radius arm drop brackets for correct caster, and two M1 monotube shock pairs, which brings the front up closer to level with the rear and adds ground clearance. Dually trucks are excluded, and trucks with rear overload springs need U-bolt kit 7649. A downloadable installation guide is available.
