6-Inch Vertex Lift Kit for Ford Super Duty 4WD (2017–2022) for Trucks with Overloads

6-Inch Vertex Lift Kit for Ford Super Duty 4WD (2017–2022), fitment-checked

Rough Country 51250 is a 6-inch lift kit for 2017–2022 Ford F-250 and F-350 Super Duty 4WD trucks, built around Vertex 2.5 coilover-style front and rear shocks, coils, radius arm drop brackets, a transfer case clocking kit, and fabricated rear blocks with U-bolts. It is limited to diesel models with factory contact overload springs. Dually, manual-shift transfer case, gas engine, 4-inch rear axle tube, and Tremor trucks are excluded.

This 6-inch lift kit for the 2017–2022 Ford Super Duty 4WD ships with Vertex 2.5 front and rear shocks, a 6-inch coil box, a radius arm kit with two upgrade boxes, a transfer case clocking kit, and a 6.5-inch block and U-bolt package. The radius arm drop brackets let you reset caster so steering behavior stays close to factory, and the anti-axle-wrap rear blocks are fabricated rather than cast. Confirm engine, axle tube, transfer case, and overload spring details against the exclusion list first, then work from the downloadable Rough Country installation guide.
