6 Inch Lift Kit | 4-link | No Ovld | C/o Vertex | Ford F-250 Super Duty (11-14)

Built for Ford F-250 Super Duty owners who want a commanding 6-inch lift with coilover adjustability and factory-corrected geometry, this 4-Link Coilover Conversion Lift Kit replaces your factory independent coil setup with Rough Country's Vertex 2.5-inch monotube coilovers. You'll gain up to 37 inches of tire clearance while maintaining proper caster and handling through radius arm drop brackets—a critical upgrade that sets this kit apart from basic block lifts.

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 (No Overloads) — Secures the rear blocks to your axle housing without factory contact overload springs.
• Box Kit — Fabricated steel frame reinforcement rated for 6-inch lift loads.
• 6-Inch Upper Arm Kit — Fixed upper control arms engineered for geometry correction.
• 6-Inch Lower Arms (Adjustable) — Allow fine-tuning of caster and ride height post-install.
• Coilover Conversion Box — Top-mounted 1/4-inch steel brackets for the new coilover mounts.
• Vertex 2.5-Inch Front Coilovers (Pair, Adjustable 4.5"–6") — Nitrogen-charged, 8-stage adjustable monotube design with external 56%-larger-capacity reservoir for superior damping control.
• Vertex 2.5-Inch Rear Coilovers (Pair, 6-Inch Fixed) — Matched rear monotube units delivering consistent ride quality and eliminating common axle wrap issues.

Important notes

• Does not fit F-350 models, gas engine models, or dually configurations.
• The new fabricated lift block replaces your factory block; confirm whether your rear leaf springs are equipped with a factory contact overload spring before ordering.
• Installation requires cutting and drilling; plan 6–10 hours for completion.
• Radius arm drop brackets preserve factory caster geometry and handling; proper alignment is essential after install.
