Built for Ford F-250 Super Duty diesel owners who want maximum ground clearance without sacrificing factory geometry, this 6-inch Coilover Suspension Lift Kit from Rough Country combines bold lift height with precision-engineered front components designed to preserve smooth, predictable handling. Run up to 37-inch tires while maintaining the truck's natural ride quality and driveline angles.

What's included

• 564s Kit Box — Ford Super Duty (11-14) structural foundation for the coilover conversion system.
• Block U-Bolt Kit overloads — Ford Super Duty rear reinforcement to maintain load-carrying capacity and rear ride quality.
• 6" Kit Box Coilover Conversion — Ford Super Duty (17-22) compatibility hardware enabling the transition from factory independent coil-shock setup to Vertex coilover suspension.
• Vertex 2.5 Adjustable Front Coilovers (Left & Right) — 2.5-inch piston, nitrogen-charged, 8-stage adjustable monotube shocks with external reservoirs offering 56% greater fluid capacity than standard reservoir shocks for superior damping control and heat dissipation.
• V2 Monotube Shock Pair (Rear) — matched rear monotube shocks for consistent damping response across the suspension.
• Radius Arm Drop Brackets — precision-fitted, fabricated brackets that bolt to factory mounts, allowing proper caster angles crucial to maintaining factory handling and driveability; stronger and longer-lasting than cast alternatives.

Important notes

• This kit does not fit F-350 models or dually configurations.
• You must confirm whether your truck's rear leaf springs are equipped with a factory contact overload spring — kit functionality depends on this detail.
• Gas-model F-250s may require exhaust modification to clear the front driveshaft during installation.
• Installation requires cutting and drilling; budget 6–10 hours for completion, though the kit is designed for home installation.

Why customers pick this at Road Runner

• Radius arm drop brackets preserve caster and factory suspension geometry — no dog-tracking, no steering wheel pulls after the lift.
• Vertex 2.5-inch monotube coilovers with external reservoirs deliver smooth, controlled damping and run cooler than standard shocks, especially under towing loads.
• Fabricated blocks outlast cast blocks and resist lift-block creep and axle wrap — the anti-axle-wrap design keeps your rig stable and predictable.
• Backed by Rough Country's lifetime warranty on manufacturer defects — honored locally at Road Runner.
• Professional alignment performed in-house as part of every lift install ensures your steering geometry and tire wear stay factory-correct.
• Our technicians install these diesel kits every week — they know the F-250 platform inside out and catch common pitfalls before they cost you downtime.
