About this kit
6-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 537.20 lifts 2005-2007 Ford F-250 and F-350 Super Duty 4WD trucks 6 inches. The box ships as a complete package: N3 shocks, front coils, two radius arm upgrade boxes, a rear add-a-leaf, and a 3-inch fabricated block and U-bolt kit. It does not fit dually or diesel-engine trucks, and the factory rear contact overload springs come off during the build.
Start with the parts list on this 6-inch lift kit for the 2005-2007 Ford F-250/F-350 Super Duty 4WD: application-valved N3 series shocks, a 6-inch front coil box, dual radius arm upgrade boxes, an add-a-leaf, and a fabricated 3-inch block and U-bolt kit for the rear. The replacement radius arms carry rubber bushings and preserve factory angles, while an adjustable cam at the axle handles caster. Rough Country lists the install as bolt-on, though the factory rear contact overload springs have to come out. Trims covered run XL through King Ranch and Harley-Davidson Edition — check the fitment section, then pull the downloadable installation guide.
