6 Inch Lift Kit | Diesel | No Ovld | C/o Vertex | Ford F-250 Super Duty (11-14)

Built for Ford Super Duty diesel owners who want 6 inches of lift without sacrificing ride quality — this Rough Country coilover conversion kit swaps your factory independent coil shocks for adjustable Vertex Coilovers, letting you run 35–37 inch tires while preserving factory-correct suspension geometry through precision radius arm drop brackets and caster-correcting design.

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

• Vertex 2.5" Adjustable Front Coilovers (Left & Right, 4.5–6 inch range) — nitrogen-charged monotube shocks with external reservoirs and 56% greater fluid capacity than standard shocks for superior damping and ride control.
• Vertex 2.5" Rear Coilovers (pair, 6 inch) — matched rear shocks with the same monotube design and adjustability as the fronts.
• Radius Arm Drop Brackets — precision-fit fabricated brackets that maintain proper caster angle and factory-like suspension geometry after the lift.
• Fabricated Rear Lift Blocks — stronger and longer-lasting than cast alternatives; anti-axle wrap design preserves stock ride quality without binding.
• Block U-Bolt Kit (no overloads) — all fasteners and hardware needed to secure the rear lift blocks.
• Complete hardware and fastener set — everything required for bolt-on installation into factory mounts.

Important notes

• This kit does NOT fit F-350 or dually models.
• Confirm whether your rear leaf springs are equipped with a factory contact overload spring — kit fitment depends on this specification.
• Gas-powered F-250 models may require exhaust modification to clear the front drive shaft after lift installation.
• Installation requires cutting and drilling; estimated 6–10 hours of labor.
