6 Inch Lift Kit | 4-link | Ovld | C/o Vertex | Ford F-250 Super Duty (11-14)

Built for Ford F-250 Super Duty owners who want a full 6-inch lift with coilover ride quality and adjustable geometry, this 4-Link Coilover Conversion Lift Kit replaces your factory independent coil setup with Rough Country's durable Vertex 2.5-inch monotube coilovers. You'll gain increased ground clearance, the ability to fit 35–37 inch tires, and proper caster geometry maintained through radius arm drop brackets — all while preserving the factory handling and driveability your truck deserves.

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

• Block U-Bolt Kit — Heavy-duty hardware to secure the rear lift blocks and distribute clamping load evenly across the axle housing.
• Box Kit — Mounting brackets and support structure for the new coilover conversion setup.
• 6-inch Upper Arm Kit — Fixed upper control arms engineered to maintain proper suspension geometry at the new lift height.
• 6-inch Lower Arms — Adjustable lower control arms that work with the radius arm drop brackets to preserve caster and driveline angles.
• Coilover Conversion Box — Fabricated mounting points and brackets for the Vertex coilover installation.
• Vertex 2.5 Adjustable Front Coilovers (pair) — 8-stage damping-adjustable monotube shocks with 2.5-inch pistons and external reservoirs; 56% greater fluid capacity than typical reservoir shocks for superior damping control and ride quality.
• Vertex 2.5 Rear Coilovers (pair) — Matching rear monotube coilovers tuned to work with the 4-Link front setup and anti-axle-wrap rear blocks.
• Radius Arm Drop Brackets — Maintain proper caster angle and driveline geometry, crucial to factory handling and durability.
• Anti-Axle-Wrap Rear Blocks — Specially designed fabricated blocks eliminate common lift-block problems while preserving stock ride quality.

Important notes

• Does NOT fit F-350 models, gas engine models, or dually configurations — confirm your truck is a 2011–2014 4WD F-250 Super Duty diesel before ordering.
• Installation requires cutting and drilling to the frame. Plan 6–10 hours for a complete install; professional installation at Road Runner is strongly recommended.
• You must confirm whether your rear leaf springs are equipped with a factory contact overload spring — this affects block selection and final ride height.
• The new fabricated lift block replaces your factory lift block; bring your VIN and suspension details to your consultation so we source the correct hardware.
• Radius arm drop brackets maintain proper caster; improper installation will affect handling and tire wear. Road Runner's in-house alignment — performed as part of every lift install — ensures caster is set correctly.
