About this kit
4.5-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 47840 is a 4.5-inch lift kit for compatible 2008–2010 Ford F-250 and F-350 Super Duty 4WD trucks, built around two M1 monotube shock pairs, front coils, and fabricated anti-axle-wrap rear blocks with U-bolts. It does not fit V-8 gas or dually models. V-10 gas trucks need exhaust modification for front driveshaft clearance, and factory rear overload leafs have to come out.
This 4.5-inch lift kit for the 2008–2010 Ford Super Duty 4WD covers F-250 and F-350 trims from XL and XLT up through Lariat, King Ranch, FX4, Cabela's, and Harley-Davidson Edition, plus 2008–2009 F-250 XL and XLT applications listed in the fitment section. The bolt-on package pairs front coils with a 6.5-inch fabricated block and U-bolt set, and radius arm drop brackets keep caster where the factory geometry wants it. Confirm your engine and rear-axle configuration against the exclusions first, then work from the downloadable Rough Country installation guide.
