6 Inch Lift Kit | Gas | Ovld | C/o Vertex | Ford F-250 Super Duty (15-16)

Built for Ford F-250 Super Duty owners who want a commanding 6-inch lift without sacrificing ride quality, this Rough Country Coilover Conversion Lift Kit replaces your factory independent coil-shock setup with precision-engineered Vertex 2.5-inch monotube coilovers. You'll gain up to 37-inch tire clearance while maintaining factory-like suspension geometry through radius arm drop brackets that preserve proper caster angles and smooth, predictable handling.
