The Fabtech component box provides parts for a 4-inch basic lift on 2017–2020 Ford F-250 and F-350 4WD models. As a kit component it aligns with Fabtech part numbers for that lift height and supplies essential suspension hardware. Fabtech underscores extensive R&D and quality construction; other complementary parts are generally required to assemble the full lift.
