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

Built for Ford F-250 Super Duty diesel owners who want commanding ground clearance and tire capacity without sacrificing factory ride quality, this 6-inch coilover suspension lift kit replaces the factory independent coil-shock setup with ultra-durable Vertex 2.5-inch adjustable coilovers. You'll clear up to 37-inch tires while maintaining smooth, balanced on- and off-road performance through precision-engineered radius arm drop brackets that preserve proper caster geometry.

What's included

• Vertex 2.5 Adjustable Front Coilovers (Left & Right, 4.5"–6" range) — Nitrogen-charged monotube design with external reservoir delivers 56% greater fluid capacity than standard shocks, providing optimal damping control and balanced performance both on and off the road.
• Vertex 2.5 Rear Coilovers (qty 2, 6" fixed) — Match the front lift while maintaining factory-like ride geometry and anti-axle wrap performance.
• Radius Arm Drop Brackets — Precision-fit to factory mounts and engineered to maintain proper caster angles, critical for factory handling and driveability.
• Fabricated Rear Lift Blocks with U-Bolts — Stronger and longer-lasting than cast blocks; specially designed to eliminate common lift-block issues while preserving stock ride quality.
• All Hardware & Installation Components — Complete bolt-on kit with everything needed for a full suspension transformation.

Important notes

• ONLY fits 2015–2016 F-250 Super Duty models equipped with rear factory contact overload springs. Does NOT fit F-350, dually, or gas-engine variants.
• Installation requires cutting and drilling; estimated 6–10 hours to complete. Professional installation recommended to ensure proper geometry and safety.
• Radius arm drop brackets must be precisely installed to maintain correct caster — improper installation will compromise handling and driveability.
