6 Inch Lift Kit | 4-link | No Ovld | Vertex | Ford F-250/f-350 Super Duty (17-22)

Built for F-250 Super Duty owners who demand a commanding stance with factory-correct geometry, this 6-inch 4-Link lift kit raises your truck while preserving handling and drivability. You get 6 inches of ground clearance, support for 35–37 inch tires, and properly set caster maintained through radius arm drop brackets — the kind of engineering that keeps your Super Duty feeling like a Super Duty, not a compromised platform.

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

• Box Kit — Ford Super Duty (17-22) — Structural foundation for the 4-Link conversion, engineered to handle the forces of lifted operation.
• 4.5–6in Up Arm Kit — Ford Super Duty (17-22) — Fixed upper control arms calibrated for the 6-inch lift, maintaining geometry across the entire travel range.
• 4.5–6in Lower Arms — Ford Super Duty (17-22) — Adjustable lower control arms that allow fine-tuning of suspension geometry and caster angle during install.
• 4.5 In Block U-Bolt Kit (No Overloads) — Fabricated rear lift blocks that replace factory equipment, stronger and longer-lasting than cast alternatives.
• Transfer Case Clocking Kit — Ford Super Duty (17-24) — Re-indexes the transfer case to maintain proper driveline angles and prevent vibration.
• Vertex 2.5 Front Shocks (qty 2) — 6 In — Nitrogen-charged N3 series shocks tuned for balanced on and off-road performance on your lifted F-250.
• Vertex 2.5 Rear Shocks (qty 2) — 6 In — Matched rear shocks that work with the anti-wrap blocks to maintain ride quality while eliminating binding.
• 6 Inch Coil Box — Ford Super Duty (05-22) — Lifted coil spring perches that support the 6-inch raise without sacrificing factory ride characteristics.

Important notes

• Does NOT fit F-350 models, gas engine models, manual shift transfer cases, dually models, or models with 4-inch rear axle tubes.
• Does NOT fit vehicles equipped with rear factory contact overload springs or the Tremor Factory Trim Package.
• New fabricated lift block replaces the factory-equipped block — part of the conversion to 4-Link geometry.
• Radius arm drop brackets are critical to maintaining proper caster angle; professional alignment after install ensures correct drivability.
