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.

Fitment is limited to diesel models with factory rear contact overload springs; gas, dually, manual-shift transfer case, and Tremor Factory Trim Package trucks are excluded, and 10-speed transmission trucks require removal of the dial pin. Radius arm drop brackets keep caster in the factory range, and the fabricated rear blocks are shaped to resist axle wrap.
