About this kit
6-Inch Vertex Lift Kit, fitment-checked
Rough Country 59450 is a 6-inch lift kit for 2008–2010 Ford F-250 and F-350 Super Duty 4WD models with a diesel engine. The kit pairs 6-inch front coil springs and a rear add-a-leaf with a 3-inch block and U-bolt kit, plus Vertex 2.5 shocks front and rear. It does not fit gas-engine or dually trucks.
This 6-inch lift kit for the 2008–2010 Ford Super Duty 4WD covers F-250 and F-350 trims from XL and XLT through Lariat, King Ranch, FX4, Cabela's, and the Harley-Davidson Edition. Front height comes from a 6-inch D-coil; the rear uses an add-a-leaf with a 3-inch block and U-bolt kit, and rear overload leafs must come out during the build. Radius arm drop brackets keep caster where it belongs for factory-style steering feel. Gas-engine and dually trucks are excluded. Work through the downloadable Rough Country installation guide before you start.
