6 Inch Lift Kit | Diesel | Fr D/s | C/o V2 | Ford F-250/f-350 Super Duty (17-22)

Built for diesel Super Duty owners who want to dominate trails without sacrificing ride quality, this 6-inch coilover conversion lift kit combines aggressive ground clearance with factory-like handling geometry. You'll run 35–37 inch tires while Rough Country's radius arm drop brackets and Vertex 2.5-inch monotube shocks preserve the suspension angles that keep your truck driving smooth.

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

What's included

• 6-inch lift kit box — structural core of the suspension system, engineered to work with the coilover conversion.
• Coilover conversion kit — replaces the factory independent coil-shock setup with a complete coilover platform.
• Vertex 2.5-inch adjustable front coilovers (pair) — nitrogen-charged monotube design with 8-stage damping adjustment and 56% greater fluid capacity than standard shocks for superior oil cooling and control.
• Vertex 2.5-inch monotube shock pair — matched rear shocks tuned for the 6-inch lift geometry.
• Radius arm drop brackets — precision-fit to factory mounts and machined to maintain proper caster angle, preserving factory handling and driveability.
• CV front driveshaft (diesel 4WD) — engineered for the geometry change and optimized for diesel torque.
• 4.5-inch fabricated rear blocks with u-bolts — stronger and longer-lasting than cast alternatives; anti-axle wrap design maintains stock ride feel.

Important notes

• Diesel models only — does not fit gas-engine Super Duty trucks.
• 4WD only — not compatible with 2WD configurations.
• Requires vehicles equipped with rear factory contact overload springs — will not work on models without them.
• Does not fit dually models.
• Does not fit manual shift transfer cases.
• Does not fit trucks equipped with the Tremor Factory Trim Package.
• Installation requires cutting and drilling; plan 6–10 hours for completion.

Why customers pick this at Road Runner

• Radius arm drop brackets maintain factory caster angles — corrected geometry means your truck handles like stock, not like a lifted truck.
• Vertex 2.5-inch monotube coilovers with external reservoir deliver 56% greater damping capacity than typical shocks — less fade, better control on rough terrain.
• Rough Country lifetime warranty backed by local in-house service — no mail-in hassles.
• Professionally installed by technicians who set up these kits every week — the difference shows in handling and tire wear.
• Professional alignment performed in-house as part of every lift install — caster, camber, and toe dialed in before you drive.
