Rough Country 55058 is a 4.5-inch lift kit for diesel 2017-2022 Ford F-250 and F-350 Super Duty 4WD models, built around adjustable Vertex 2.5 front coilovers, a V2 monotube shock pair, a front CV drive shaft, and fabricated rear blocks with U-bolts. It does not fit gas engine, dually, manual shift transfer case, or Tremor Factory Trim Package trucks, and only works with rear factory contact overload springs.

This 4.5-inch lift kit for the 2017-2022 Ford F-250/F-350 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, Platinum, and Limited diesel trims listed in the fitment section. The coilover conversion uses left and right Vertex 2.5 adjustable front units rated across a 4.5IN-6.IN range, paired with a V2 monotube shock set out back and radius arm drop brackets that keep caster where the factory set it. Rear blocks are fabricated and designed to resist axle wrap. Trucks with the 10-speed transmission need the dial pin removed. A downloadable installation guide is available.
