6 Inch Lift Kit | 4-link | No Ovld | D/s | C/o V2 | Ford F-250/f-350 Super Duty (17-22)

Built for Super Duty owners who demand a 6-inch lift without sacrificing ride quality, this 4-Link Coilover Conversion Kit replaces your factory independent coil-shock setup with adjustable Vertex 2.5-inch monotube coilovers. You get increased ground clearance, proper caster geometry through radius arm drop brackets, and the ability to fine-tune ride height and dampening — all while maintaining factory handling characteristics. The kit accommodates 35–37 inch tires.
