6-Inch Vertex 2.5 Coilover Lift Kit, fitment-checked

Rough Country 55658 lifts the 2017–2022 Ford F-250 and F-350 Super Duty 4WD 6 inches using adjustable Vertex 2.5 front coilovers and a 4.5-inch fabricated rear block with a no-overload U-bolt kit. Diesel, non-dually trucks only: gas engines, manual-shift transfer cases, dually axles and the Tremor Factory Trim Package are not covered.

A 6-inch lift kit for the 2017–2022 Ford F-250 and F-350 Super Duty 4WD, narrowed to diesel, single-rear-wheel trucks. Gas engines, manual-shift transfer cases, dually models and the Tremor Factory Trim Package all sit outside its coverage. Front height comes from left- and right-hand adjustable Vertex 2.5 coilovers rated across the 4.5-6 in range, with a V2 monotube shock pair, a radius arm kit plus two radius arm upgrade boxes, and a transfer case clocking kit. At the rear, a 4.5-inch fabricated block and U-bolt kit without overloads takes over from the factory block. Trucks with the 10-speed transmission need the dial pin removed.
