Rough Country 58858 is a 6-inch lift kit for 2008-2010 Ford F-250 and F-350 Super Duty 4WD trucks. The kit pairs Vertex 2.5 adjustable front coilovers with a V2 monotube shock pair, radius arm drop brackets, upper and lower arms, an add-a-leaf, and a 3 inch block and U-bolt kit. It does not fit dually models.
This 6-inch lift kit for the 2008-2010 Ford Super Duty 4WD covers F-250 and F-350 trims from XL through King Ranch, plus the 2008-2009 F-250 4WD listings shown in the fitment section. Vertex 2.5 adjustable front coilovers and a V2 monotube shock pair handle damping, while the radius arm drop brackets keep caster set close to factory geometry.
