4.5 Inch Lift Kit | C/o Vertex | Ford F-250/f-350 Super Duty 4wd (2017-2022)

Built for Super Duty owners who want maximum ground clearance without sacrificing ride quality, this 4.5-inch coilover conversion lift kit replaces the factory independent coil-shock setup with premium Vertex 2.5-inch adjustable coilovers. You'll run up to 35-inch tires while maintaining factory-like suspension geometry through precision radius arm drop brackets — the key to preserving handling and driveability.
