6 Inch Lift Kit | 4 Link | Ovld | C/o Vertex | Ford F-250 Super Duty (15-16)

Built for F-250 Super Duty owners who want a 6-inch lift with coilover ride quality and proper geometry, this 4-Link Coilover Conversion Lift Kit replaces your factory independent coil setup with adjustable Vertex Coilovers and a purpose-built control arm geometry. You'll gain up to 37" tire clearance while radius arm drop brackets maintain proper caster — the foundation of factory-like handling after the lift.

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 fastening for the fabricated lift blocks, engineered for strength and longevity.
• 6" Up Arm Kit — fixed upper control arms that work with the 4-Link geometry.
• 6" Lower Arms — adjustable lower control arms for ride height tuning and proper suspension geometry.
• 589 Box Kit & 6" Kit Box (Coilover Conversion) — top-mounted reservoir brackets and coil-over mounts fabricated from 1/4-inch steel.
• Vertex 2.5 Adjustable Front Coilovers (Left & Right, 4.5"–6" range) — monotube design with external reservoir, 56% greater fluid capacity than average reservoir shocks, 8-stage adjustable damping.
• Vertex 2.5 Rear Coilovers (6", qty 2) — matched pair for balanced rear support and ride quality.
• Radius Arm Drop Brackets — maintain proper caster geometry and allow for precise caster angle correction.
• Anti-Axle Wrap Rear Blocks — fabricated design eliminates binding and preserves stock ride feel while handling lift loads.

Important notes

• Does not fit F-350 models, gas-engine trucks, or dually configurations.
• New fabricated lift block replaces factory lift block — not compatible with OEM block.
• Installation requires cutting and drilling; estimate 6–10 hours for full completion.
• Radius arm drop brackets are critical to caster correction — professional installation and in-house alignment strongly recommended.
