6 Inch Lift Kit | Gas | 4 Link | Ovld | C/o Vertex | Ford F-250/f-350 Super Duty (05-07)

Built for Super Duty owners who want a coilover suspension upgrade with true ride height adjustability and factory-correct geometry, this 6-inch 4-Link Coilover Conversion Lift Kit replaces your factory independent coil setup with a dual-stage adjustable Vertex Coilover system. You'll gain 6 inches of front lift, level stance, and the ability to dial in your ride quality — all while maintaining proper caster geometry for factory handling and driveability. Supports 35"–37" tires.
