4.5 in. Vertex Coilover Lift Kit, fitment-checked
Rough Country 400359 is a 4.5-inch lift kit for 2023-2025 Ford F-250 and F-350 Super Duty 4WD models, built around left- and right-hand Vertex 2.5 adjustable front coilovers, a pair of Vertex 2.5 rear shocks, a secondary V2 monotube front shock pair, tubular radius arms, and a rear block and U-bolt kit. It does not fit gas-engine, Tremor Off-Road Package, or dually trucks.
This 4.5-inch lift kit for the 2023-2025 Ford F-250 and F-350 Super Duty 4WD covers XL through Limited trims, including King Ranch, Lariat, Platinum, and XLT. The front end converts to Vertex 2.5 adjustable coilovers on 1/4-inch fabricated mounts with a reservoir bracket, and 2-inch outer diameter tubular radius arms restore caster and keep suspension angles closer to factory. Fabricated rear blocks and matched U-bolts handle axle wrap out back. Rough Country lists the install as bolt-on with no cutting or drilling, and a downloadable installation guide is available. Confirm your engine and package against the exclusions first.
