About this kit
6-Inch Lift Kit with Vertex Coilovers, fitment-checked
Rough Country 57858 is a 6-inch lift kit for 2005-2007 Ford F-250 and F-350 Super Duty 4WD trucks. The kit pairs adjustable Vertex 2.5 front coilovers with a V2 monotube shock pair, an add-a-leaf, and a 3-inch block and U-bolt kit for the rear. It does not fit dually models, and the exhaust must be modified for front driveshaft clearance.
This 6-inch lift kit for the 2005-2007 Ford F-250 and F-350 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, and Harley-Davidson Edition trims listed in the fitment section. Front height comes from left- and right-hand adjustable Vertex 2.5 coilovers, with upper and lower arms plus radius arm drop brackets to set caster back where the factory geometry wants it. The rear uses an add-a-leaf with a 3-inch block and U-bolt kit. Confirm your truck is not a dually and plan on exhaust modification for driveshaft clearance before you start.
