About this kit
6-Inch Lift Kit with Vertex Shocks, fitment-checked
Rough Country 53659 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 Vertex 2.5 rear shocks, heavy-duty radius arms, an add-a-leaf, and a 3-inch block and U-bolt package. It does not fit dually models, and the factory rear contact overload springs come out during installation.
This 6-inch lift kit for the 2005–2007 Ford F-250/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 rated across a 4.5-in to 6-in range, while the rear uses an add-a-leaf with fabricated blocks and new U-bolts. Replacement radius arms with rubber bushings hold factory geometry, and an axle-end alignment cam allows caster adjustment. Assembly is bolt-on, and a downloadable installation guide is available. Confirm your truck is not a dually before ordering.
