6 Inch Lift Kit | Diesel | 4 Link | Ovlds | C/o V2 | Ford F-250/f-350 Super Duty (05-07)

Built for Ford Super Duty 4WD owners who want aggressive lift with ride-quality tuning, this 6-inch 4-Link Coilover Conversion transforms your first-generation Super Duty into a capable, adjustable platform. The conversion replaces your factory independent coil-shock setup with Rough Country's 2.5-inch Vertex Coilovers — nitrogen-charged monotubes with external reservoirs that deliver 56% greater fluid capacity than standard shocks. You'll accommodate 35"–37" tires while maintaining proper caster geometry through radius arm drop brackets that keep factory handling and driveability intact.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.
