Rough Country 55057 is a 4.5-inch lift kit for 2017–2022 Ford F-250 and F-350 Super Duty 4WD models with a diesel engine. The kit is built around adjustable Vertex 2.5 front coilovers and Vertex 2.5 rear reservoir shocks, plus fabricated rear blocks, U-bolts, and a transfer case clocking kit. It does not fit gas engine, dually, manual-shift transfer case, or Tremor Factory Trim Package trucks.
