Rough Country 50659 is a 4.5-inch lift kit for compatible 2017-2022 Ford F-250 and F-350 Super Duty 4WD diesel models. The kit converts the front to adjustable Vertex 2.5 coilovers, pairs them with Vertex 2.5 rear shocks, and adds a front CV drive shaft, fabricated rear blocks, and U-bolt hardware. It does not fit gas-engine, dually, manual-shift transfer case, or Tremor Factory Trim Package trucks.

This 4.5-inch lift kit for the 2017-2022 Ford F-250/F-350 Super Duty 4WD covers XL through Limited trims, including King Ranch, Lariat, Platinum, and XLT, as listed in the fitment section. Front lift comes from a pair of adjustable Vertex 2.5 coilovers rated across a 4.5 in to 6 in range, with radius arm drop brackets to keep caster where the factory geometry wants it. The rear uses two Vertex 2.5 shocks and fabricated anti-axle-wrap blocks with new U-bolts. Trucks must have rear factory contact overload springs. A downloadable installation guide is available.
