6 Inch Lift Kit | Ovlds | D/s | Ford F-250/f-350 Super Duty 4wd (2017-2022)

Built for Super Duty diesel owners who want factory-smooth ride quality with 6 inches of ground clearance — this lift kit combines precision-engineered radius arm drop brackets, fabricated anti-wrap rear blocks, and N3 shock absorbers to preserve suspension geometry while letting you run 35–37 inch tires without sacrificing drivability.
