About this kit
6-Inch Lift Kit with Vertex 2.5 Shocks, fitment-checked
Rough Country 58450 is a 6-inch lift kit for 2008-2010 Ford F-250 and F-350 Super Duty 4WD diesel models. The kit pairs Vertex 2.5 front and rear shocks with radius arm drop brackets, lower arms, coil springs, an add-a-leaf, and a 3-inch block and U-bolt package. It does not fit dually or gas-engine trucks, and rear overload leafs must come off during the build.
This 6-inch lift kit for the 2008-2010 Ford F-250 and F-350 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, FX4, Cabela's, and Harley-Davidson Edition trims. Front lift comes from coil springs with upper and lower radius arm drop brackets that keep caster set where the factory intended, while the rear uses an add-a-leaf with a 3-inch block and U-bolt kit. Vertex 2.5 shocks are matched front and rear. Confirm your truck is a diesel single-rear-wheel model before ordering, then work from the downloadable Rough Country installation guide.
